Documented Engine tear down by Hungarian Mazda dealer
I just curious, what language this is and if anyone speaks it. I came across it randomly.

I tried chrome, it sucked, images on this site often would not load, etc. and doesn't work on several business sites I have to visit. But I guess I'll try it for this purpose.

The picture pretty much spoke for itself.
The bearing is done, e shaft looks fine. Rotor carbon normal, rotor housing has heat spot which is normal for stock engines with no fin mod plus I see chrome flaking which means it's bad.
I'm pretty sure the engine was run with thin oil cuz of the wear on bearings.
Oh btw, chrome sucks, it doesn't work with lots of sites, it crashes and all the fake fast loading annoys the crap outa me

Works fine for me. No issues on any sites I use. I also have my tweaked very heavily. Lots of plugins and settings tweaks. But, I'm also the guy with his PC overclocked as far as it will go, on everything. Nothing stays stock for long on my rig. lol

^My mind is blown.
I have a custom rig too, but it was built for me. Haven't had the time to really learn near as much as I'd like with computers, it's a shame.
I'm interested as to what plugins you're running myself. It's taking quite a bit to translate for me, as well.

It's a long article about an engine torn down after 100,000 kms so about 63K miles, with oil changes done only every 12.5K miles ...
Hungarian is my native language, so I can translate it for you if automated translation methods are not sufficient (which is probably the case) - but it will take some time
I'll try to take time tonight and do the translation.
By the way, the web site is of an official Mazda dealer / service in Hungary who are considered one of the most knowledgeable dealers over there about the RX-8.

Mazda RX-8 rotary engine disassembly.
Right in the middle of a cut in a Mazda RX-8.1 million kilometers mileage, and service documentation that, unfortunately, only very rarely, done 20,000 miles per oil change. Disassemble the engine, let's see how wearing the rotary engine parts authoritarian past ordeal!
Rarely straightforward.
Of course, before anyone would think that Mazda brand experience just in our service to collect was removed and disassembled in a Mazda RX-8 engine, I must say that the car engine problems have occurred in the past. The cold immediately after the initial warm-up wankelt could not be stopped to start the following hypothermia. The car owner had told us of "collapse" is also used catalytic converters the car, just not warm to the aforementioned issue, prior to departure. The possible consequences into account and all related options after exclusion (such as spark plugs, coils, etc ...) only the left engine failure option. This is a somewhat weak power output has been confirmed.
A breakdown of the inside of the engine before it is worth taking a look at the oil delivery system jets that make up the engine oil leaks from the ventricles (apex, corner, side) serve to cool.:
The nozzles are perfectly clear, and 100 000 km to 20,000 km by Mazda changed Dexelia 5w-30 motor oil after use. Of course it would be surprising if they were contaminated, because the engine "vacuum phase" of the trochoid houses are located, so the effect of vacuum them departing air-oil mixture to prevent deposition of dirt, oil, irrespective of quality.
They are not dirty.
It is also worth examining the breakdown of the engine before the 231-horsepower RENESIS 13B-MSP-cylinder intake control valves (APV) as well. Despite the 100,000 km mileage, remained relatively pure components, were still very far from the accumulated coke may result from dysfunction. The picture is unfortunately only after the cleaning is one of the control cylinder, so that the reader have to believe me.
The first eccentric shaft bearings.
Turning the engine start sequence, the first zárófedéllel The inner surface of one side to the first planetary piston housing when stored. More precisely, this positioning of the lid is fixed gear and the eccentric shaft bearing housing.

The house is inside the eccentric shaft can be seen in plain bearings. The plain bearings operating principle is based on the bearing pressure bejutatott oil, forming a film on the shaft and prevents metallic contact between the bearing housing.

The bearings agitated olajnyomásból the oil quantity can be inferred. More pressure = more oil. Details írásainkban MOTOR OIL, HERE and HERE.
As can be seen in the previous two pictures, unfortunately, this is a very plain bearings are worn condition. Internal combustion engines are rarely encountered such abnormal extent, even after not much more mileage. The 13B-MSP RENESIS rotary engine is often the case unfortunately. This type of wear is not really justified by any operational condition, or immediately after a Cold Start ruthless drive, or persistently low engine oil usage, inadequate cooling ... But even these exceptions are not really the truth, because one engine wear can have similar experience, and every owner is not liable to make mistakes, and the construction in this area should be protected against errors. Unfortunately, so has to be said to be primarily due to the design defects of this kind of wear problem. This is even more puzzling, as a plain bearing oil supply to non-specific "rotary thing" - such as leaks Lubrication -, "" just scale should have the lubrication system and / or components, but more about that later still more, the eccentric shaft bearings at the rear.

Nevertheless, as the following pictures show, the first planetary piston sliding surfaces of the side or apex of the orbit leaks tax trochoid surface is surprisingly good shape for the distance 100,000 km of operation, and maintenance in spite of the weak.

A 2.5-liter gasoline engine piston Mazda6 in the same calculated average values of the piston rings during this period shall be: 72000 km on the cylinder surface .. This is roughly 30% less than the load, lubrication differences (to the detriment of the rotary engine), not to mention now. 2,5 In addition, a relatively long stroke resources, a short-stroke engine has less mileage of the rings.
RENESIS-our (renezisz) in the first trochoid rotor housing ("Oval") orbits, and the sliding surface shows a rather significant wear at the edges, the edges partly be attributed to increased heat load on the side exhaust ports due. This is so despite the fact that the engine oil cooler is to arrive in larger quantities in the picture above shows two tiny black hole.
The picture shows one of the first planetary piston housing oldalfedelének exhaust openings can be seen. The previous Mazda wankeleken peripherally located after the exhaust ports, the RENESIS introduced via side-mounted slot One aim of the special shape of the lateral and corner seals éltömítéseket clean the carbon deposits. Effectiveness of the operation of the vent deposits at the narrow end is visible. Why or less carbon-like material deposited in the engine, or perhaps more long-term loads in intermittently left the deposited amount. A small deposit may also be evidence that these parts is really a gasoline combustion of hard coal deposits in the origin can be rather small compared to the volume of the unit volume of combustion of motor oil. Apart from a detailed technical explanation, if it originated from the oil deposits in the engine, the engine oil change in our more neglected in terms of deposition should be.
The first rotor (piston planet) the other side of the side exhaust port is also quite clear:
One could say that 900 degrees Celsius there is little chance of engine oil, but it seems not only to oil combustion products, but much greater quantities are generated from the combustion of gasoline-like carbon deposition can not accumulate. The picture above is clearly visible in the side sliding surface is quite normal, "porous" (right olajmegtapadás) surface.
The first planetary piston, ie, the first rotor
The authoritarian Wankel engines, so the Mazda RENESIS 13B-MSP in the planet's eccentric shaft piston trajectory of ham, and have presented in this article defines positioning gear, not the trochoid housing "oval" of his career. The planet piston (rotor) is not physically touch the surface of the sliding housing trochoid, only put into them in contact with the sealing surface trochoid or lateral ventricles side boundary with lids.
Thus, the rotor principle not kophat if the bearings, positioning the gear and the eccentric shaft bearings does not allow for "hanging out" for the incorrect path. But before megörülnénk this news, the rotor can spit, bearing still intact as well. The rotor seal is located, whichever is first apex of the leaks continued movement on the rotor vályatukban trained. The seal between the nest and the combustion products, the effect of movement of seals, gaskets and worn under the blows of the tolerance of the koptathatják tömítésfészkek width. However, after 100 000 km of the planet, this piston in this respect is re-usable state.
The rotor friction bearings (picture above) is considered in good condition, compared to the previously discussed threadbare eccentric shaft bearings. The side "oil seals" and the intake and exhaust ports together-working to prevent the sealing ring (cut off) also remained in good condition, without substantive changes, easily moved gyűrűfészkeikben.
It is because of these planets piston kokszossága not be fooled by anyone! The important points were not igazás "problem" that deposits on the rotor and the assembly during the current engine oil coke is "rondítja the photos." Although the positioning of the gear is not in place, clearly visible in the picture above (rear rotor, not the first), the importance of nearly 4 kg of rotor mass balance and precise guidance of, for example, by an eccentric shaft bearing is worn, may be affected.
Apex, heel, lateral leaks (rotor 1).
We have reached our engine piston of the first planetary éltömítéseihez apex of the corner seals and side éltömítésekhez for which data sharing is now wearing a nice reader.
A piece apex bolygódugattyúnak three leaks, which are located on the vertices of the rotor and the housing trochoid sliding ensure the tightness of the chambers, the six-cylinder corner seals, and also six éltömítéssel side together.
Mazda officially allowed to wear 1 mm thickness from the apex leaks, which they consider an average of around 240 000 km occurs. This figure is certainly not considered légbőlkapottnak as engine for the first bolygódugattyúján all three apex seals 0.5 mm et worn on the 100,000 km of use, and as you decrease the weight and thickness (a rounded crown), wear and tear slow down somewhat. Lateral surface is also measured in the up and down movement due to wear, although this is also not assumed a critical objective.
The image above lateral compression leaks size remained virtually default value 100000 km running performance after the first bolygódugattyún. Tömítésfészekbe prevent constipation caused by the deposition of the wedge-shaped éltömítéseknek training is that it seems it worked perfectly, because each of the six leaks freely moving nest.
The second planetary piston housing.
The second rotor on one side of the middle intermediate (intermediate) is bounded by housing, which is the opposite side of the rear rotor of the first timber is running. In the middle section, as opposed to two végfedéllel, not embedded in the eccentric shaft bearings.

The first planet in relatively good condition, piston against the side surface of the cover image is visible, the exhaust port is fairly worn around the second rotor side seals sliding surface of the intermediate casing. But the picture also shows that the exhaust port "deposit removal" function right corner holding a little saturated. It is seen from the first rotor.
In the meantime, the home side surface of sliding surfaces of the rotor housing trochid continued again 'dark' image as the house was the first rotor. The surface is highly uneven in some places show wear and scrapes. Yet one of the most worrisome gyertyanyílástól (Leading) the initial transverse crack.
Mazda RX-8 13B-MSP trochoid felület.
The second chamber rear wall of the sliding surface of the lid which last too many new things I can not say. Not as healthy as the first chamber, but the exhaust port deposits are also not insignificant. Overall, the wear can be stated that the second planetary piston housing is much higher thermal load has been exposed as the first, but the strong suspicion that sometimes too rapid temperature change is "suffering" components. Instead, it is not sufficiently gentle warm-up pose. Probably the trochoid housing is therefore allowed the surface of the narrowest part of it.
The second piston planet, that is, the second rotor
This writing covered Mazda rotary engine 13B-MSP-based resource bolygódugattyúja second - as the first rotor - újrafelhasznáható 100,000 km of state until after the work performed. The planet tömítésfészkeinek piston size remained within the tolerance of the seal movements have already been discussed so far have not caused excessive wear. The motion for stay, the rotor was moving freely in each nest seals, gaskets deposits due to "grab" could not be established.
The eccentric shaft csapágyazásánál much larger planet with a diameter piston sliding bearings remained in relatively good condition, but it is not so much a re-run with raknánk used motor bearings, if you were to take place. The rotor gears are also not visible signs of wear. It seems that these parts of the engine oil was able to cope with the increased heat load.
Apex, corner, side leaks, the second rotor
This is probable but greater heat load in the apex éltömítéseken clearly noticeable if we compare their wear rate of the first "triangle" of the same piston seals. The rear rotor for all three apex éltömítésének 0.1 mm smaller in height than the first rotor seals can be measured the same values.
The side virtually no measurable wear, leaks, and their distance from the corner seal is below the tolerance limit. The springs also seals remained in good condition.
The eccentric rear axle bearings.
The beginning of this article has been viewed, how worn the eccentric shaft (the main axis of the rotary engine), the first surface of the plain bearing. Unfortunately the same can be said of the other bearing axle of the rear cover which is bolted to the positioning of the gearbox. It seems eccentric to the axis of movement during the RENESIS sometimes csapágyaiból squeeze out more oil than the oil supply coming into them. The times and temperatures are in speed, or even ruthless about start-up conditions. Rádásul bearing such attrition after several replacements for oil would be needed.
The higher the temperature of the bearing, and the higher the speed, the higher the oil pressure would be required to provide sufficient quantities of motor oil can circulate through the bearing. Many people believe that a higher viscosity oil can be warm side of the gap, but the thicker the oil the same pressure, flows more slowly, so that less oil is less able to cool the bearing. Consequently, the bearing temperature increased more in the thinned engine oil, which slowly comes to succession. Thus xxw-40-inch or 50-xxw motor oil, we do not really advance.
In fact, it may be to say that the Mazda engineers have created the largest-speed rotary motor known, the lowest ever value of the maximum oil pressure (5.1 bar max.), To mention only the basic anomaly. In addition, it is just one part of the problem. Of course, we have applied some balm mean mazda auto-I Phase II and mazda-auto. phase, which is a step forward in solving complex problems. Click here to read these types.
The eccentric shaft or the rotary main shaft.
The eccentric shaft is practically the main axis of the rotary piston engine equivalent. The eccentric shaft to get the rotors sonkáinak planetary motion of the drive clutch for rotary motion. The eccentric shaft slide bearing ensures the rotors of oil supplies, but also cool the inside of the rotor away from the engine oil (oil jet) provides.
If a unit of speed, more oil flows through the center of your engine oil zási eccentric shaft, the more oil is cooled by the bolygódugattyúkat. The shaft wear is not so typical, since the bearing metal is softer, more shock to the axle should be checked, but the shaft was found to be good.
I prefer new.
The all-new car factory (Japan only) engine was assembled, because the new owner's expectations based on a minimum of 100 000 km of new power sources seamlessly meet. This is all the chances, as it is now at 10,000 per km will be replaced with engine oil, which is now a fully synthetic 0W-30 multigrade lubricant index will be. Shorter oil change intervals, or fully synthetic oil "stable" the steadfastness of the next oil change is itself a great step forward. The hypothermia less visszadermedő lower cold side labeled motor oil will also assist the eccentric shaft átolajzását faster startup, which in this case the eccentric shaft bearings the load is reduced. This further step up the mazda auto-II phase is immediately entered into the new engine.
The RENESIS resilience of matching, greater quantities of oil transportation (motor) also I. applikált mazda auto- phase provides. In addition, the engine break-in can now provide much help to the provision of life. The first 750 km up to 3000-3500's and 1000 km in some cases up to 4000 rpm-res pörgetve become the new engine.
There is also a private opinion, I note that quite a number of Hungarian Mazda RX-8 test car began his career as a serious and, unfortunately, information, raise awareness in the absence of these cars had no chance for the aforementioned gentle entrance. Respect to the exceptions of course.
Old and new.
The resulting compression of this problem is likely to warm the house back trochoid-wear damage caused by the previous engine. In addition to rapid changes in temperature cause cracks, which could cause even gyújtáskimaradás, warming harsh, or both. The trochoid housing replacement or renovation of a professional seal all necessary costs, machinery work is carried out, and the total amount of fees that kick, which is almost a complete new engine factory price. Moreover, in this case is still in a restored engine will (some of the less worn, but worn (!!!) parts), so I assume needs no explanation, that such an engine is not in the same life expectancy as a completely new wankeltől. Varga Stephen (20-9577080)
WARNING! Other rumors in Europe only in Japan, assembled in a complete new factory distributor of Mazda engines. These engines are not renewed, which is based on the engine number is clearly justified. Factory reconditioned engines exclusively for the North American distributor representing Mazda, but they can not be imported.

The second chamber rear wall of the sliding surface of the lid which last too many new things I can not say. Not as healthy as the first chamber, but the exhaust port deposits are also not insignificant. Overall, the wear can be stated that the second planetary piston housing is much higher thermal load has been exposed as the first, but the strong suspicion that sometimes too rapid temperature change is "suffering" components. Instead, it is not sufficiently gentle warm-up pose. Probably the trochoid housing is therefore allowed the surface of the narrowest part of it.
The second piston planet, that is, the second rotor
This writing covered Mazda rotary engine 13B-MSP-based resource bolygódugattyúja second - as the first rotor - újrafelhasznáható 100,000 km of state until after the work performed. The planet tömítésfészkeinek piston size remained within the tolerance of the seal movements have already been discussed so far have not caused excessive wear. The motion for stay, the rotor was moving freely in each nest seals, gaskets deposits due to "grab" could not be established.
The eccentric shaft csapágyazásánál much larger planet with a diameter piston sliding bearings remained in relatively good condition, but it is not so much a re-run with raknánk used motor bearings, if you were to take place. The rotor gears are also not visible signs of wear. It seems that these parts of the engine oil was able to cope with the increased heat load.
Apex, corner, side leaks, the second rotor
This is probable but greater heat load in the apex éltömítéseken clearly noticeable if we compare their wear rate of the first "triangle" of the same piston seals. The rear rotor for all three apex éltömítésének 0.1 mm smaller in height than the first rotor seals can be measured the same values.
The side virtually no measurable wear, leaks, and their distance from the corner seal is below the tolerance limit. The springs also seals remained in good condition.
The eccentric rear axle bearings.
The beginning of this article has been viewed, how worn the eccentric shaft (the main axis of the rotary engine), the first surface of the plain bearing. Unfortunately the same can be said of the other bearing axle of the rear cover which is bolted to the positioning of the gearbox. It seems eccentric to the axis of movement during the RENESIS sometimes csapágyaiból squeeze out more oil than the oil supply coming into them. The times and temperatures are in speed, or even ruthless about start-up conditions. Rádásul bearing such attrition after several replacements for oil would be needed.
The higher the temperature of the bearing, and the higher the speed, the higher the oil pressure would be required to provide sufficient quantities of motor oil can circulate through the bearing. Many people believe that a higher viscosity oil can be warm side of the gap, but the thicker the oil the same pressure, flows more slowly, so that less oil is less able to cool the bearing. Consequently, the bearing temperature increased more in the thinned engine oil, which slowly comes to succession. Thus xxw-40-inch or 50-xxw motor oil, we do not really advance.
In fact, it may be to say that the Mazda engineers have created the largest-speed rotary motor known, the lowest ever value of the maximum oil pressure (5.1 bar max.), To mention only the basic anomaly. In addition, it is just one part of the problem. Of course, we have applied some balm mean mazda auto-I Phase II and mazda-auto. phase, which is a step forward in solving complex problems.

The eccentric shaft or the rotary main shaft.
The eccentric shaft is practically the main axis of the rotary piston engine equivalent. The eccentric shaft to get the rotors sonkáinak planetary motion of the drive clutch for rotary motion. The eccentric shaft slide bearing ensures the rotors of oil supplies, but also cool the inside of the rotor away from the engine oil (oil jet) provides.
If a unit of speed, more oil flows through the center of your engine oil zási eccentric shaft, the more oil is cooled by the bolygódugattyúkat. The shaft wear is not so typical, since the bearing metal is softer, more shock to the axle should be checked, but the shaft was found to be good.
I prefer new.
The all-new car factory (Japan only) engine was assembled, because the new owner's expectations based on a minimum of 100 000 km of new power sources seamlessly meet. This is all the chances, as it is now at 10,000 per km will be replaced with engine oil, which is now a fully synthetic 0W-30 multigrade lubricant index will be. Shorter oil change intervals, or fully synthetic oil "stable" the steadfastness of the next oil change is itself a great step forward. The hypothermia less visszadermedő lower cold side labeled motor oil will also assist the eccentric shaft átolajzását faster startup, which in this case the eccentric shaft bearings the load is reduced. This further step up the mazda auto-II phase is immediately entered into the new engine.
The RENESIS resilience of matching, greater quantities of oil transportation (motor) also I. applikált mazda auto- phase provides. In addition, the engine break-in can now provide much help to the provision of life. The first 750 km up to 3000-3500's and 1000 km in some cases up to 4000 rpm-res pörgetve become the new engine.
There is also a private opinion, I note that quite a number of Hungarian Mazda RX-8 test car began his career as a serious and, unfortunately, information, raise awareness in the absence of these cars had no chance for the aforementioned gentle entrance. Respect to the exceptions of course.
Old and new.
The resulting compression of this problem is likely to warm the house back trochoid-wear damage caused by the previous engine. In addition to rapid changes in temperature cause cracks, which could cause even gyújtáskimaradás, warming harsh, or both. The trochoid housing replacement or renovation of a professional seal all necessary costs, machinery work is carried out, and the total amount of fees that kick, which is almost a complete new engine factory price. Moreover, in this case is still in a restored engine will (some of the less worn, but worn (!!!) parts), so I assume needs no explanation, that such an engine is not in the same life expectancy as a completely new wankeltől.

WARNING! Other rumors in Europe only in Japan, assembled in a complete new factory distributor of Mazda engines. These engines are not renewed, which is based on the engine number is clearly justified. Factory reconditioned engines exclusively for the North American distributor representing Mazda, but they can not be imported.

This is a literal translation, but some of the concepts got "lost in translation".
The ideas for the failure aren't much better than blackstone, but I think most of us have seen pics like these.
Final translation: Renesis kaput!
Owner ran the **** outta car on too long an oil change and a too light weight oil, didn't premix, and ran with misfires.
