In addition to the bad spark plugs, we found two bad oil injectors. We will be starting this soon, and we are very curious to see if the coils are bad. We doubt they have been replaced.
As usual the rotor housings needed to be replaced with new ones, in addition to new soft/hard seals. Stationary gear bearings also needed to be replaced. Surprisingly the front thrust assembly was all toast. One needle bearing fell apart while cleaning, never seen that before. The thrust plate had a lot of wear. We failed to check end play before taking the engine apart, I suspect it was out of spec. We also had to replace the oil pickup tube, a lot of junk inside it on the other side of the screen. We've seen this on a few MSP(s) lately. |
Car is finished. Recalled K&N intake threw us through a loop for a while...
|
Looks good, what is the thrust assembly?
|
That's almost what my spark plugs looked like on my first motor that had about 30,000 miles on
|
damn and i thought my plugs looked back after 20k

Another rebuild hmm ... |
so... I'm not going to have to worry about engine replacements if I keep the maintenance up right...?
what's the average life if taken care of with the Renesis? |

what's the average life if taken care of with the Renesis? Even all of the above cannot prevent the engine loosing compression over time from too much sideseal to corner seal gap during engine assembly. |
there's upgraded coils that last a little bit longer right?
sorry for all the Q's.. I just wanna know as much as I can. what's the average fail age in your experience? B4 100k miles? (so still in warranty). Supossedly the motor gets better over time... I wanna buy a car that'll last...and I love the rx8.. I'm not a 2 year buy a new car kinda guy. |
Nice photos. Any in depth pictures of the e-shaft and rotor bearings?

all this did not happen in the last 25K---so it is a testenemt to the rotary to be running at all in that kind of condition.
No wonder airplane guys like it, Is everyone SURE premix is helping this engine? OD |
ragger! havent heard from you in a while!
|
im approaching 100k ..this is worrying me!
|
Have you seen the outter control rings cracking and splitting allowing blow by? Basically you have 2 C's when removing the oil control rings. I have seen this now in the renesis I have torn down that were smoking. Nice sharing the port work in the photo.

OD http://www.jabiru.net.au/ There is nothing even remotely similar for Wankel rotaries. |
Sorry --should have clarified a little more---its the homemade small sport planes owners that are saying they like the rotory engine because of its small size and light weight. They do also mention that the engine never just quits--it may loose power but it doesnt just quit like recips do when they drop a valve, etc.
Sorry for the highjack--back to the original topic. |
Great Pics..thanks..and great assembly.
Sure looks like a Carbon Lock engine, the removed Apex Seals don't look that bad, I have seen worse at half the mileage. As we know the Apex Springs just cant keep the Apex Seals contacted to the Rotor Housings because of all the carbon build up. That spark plug is disgusting. |
When an engine is running the majority of the apex seal force is from combustion pressure; just like a piston rings. This is why its also critical to have correct apex seal to groove clearances...
Put a few hundred miles on car, runs great. It was delivered this morning. And we had a few more roll into today, next build will be much more performance orientated.. |
