Compression Test Check This Out!

Brief summary of what has happend. Had noise from the engine and serious vibration, took the car into Mazda, even had the service manager take a ride with me. He claims that there is no issue, MNAO refuses to order the dealer to look into the issue further, (compression tests etc). Finally after being told it was faulty motor mounts I was fed up with Mazda's ****. I went and had a compression test done, (and paid for it) from a rotary mechanic. We compaired the findings to the specifications in Mazda's workshop manual. See the attached results and laugh your *** off at the fact that Mazda is blaming my issue on faulty motor mounts!!!!

and the workshop specifications...

I know it's hard to see after it opens up totally on your screen so here are the results:

COMPRESSION/TEST
#1 ROTOR 111 PSI
#2 ROTOR 80 PSI

According to the workshop manual there should not be more than a 14.5PSI difference between the two rotors!

There should be three reading from each rotor.....there are three faces to each rotor. They are also very dependant on cranking RPM

The test results that you have seem to indicate a big problem with the rear rotor though

It probably is the highest reading from each rotor. It doesn't really give you much info other than things are really F**Ked in rotor 2. The extent of the damage would be easier if you had the descrete chamber readings.

It really doesn't matter much though if it's on Mazda'd dime....you definitely will need some major motor work

That's the thing, Mazda won't even look into the issue. The service manager at Hempstead All Star Mazda in NY, went with me for a ride confirmed the noise, then blamed the issue on vacuum noise coming from the intake. Also stated that it may be my clutch due to the fact that in 2nd gear (according to the service manager), I should be going 80mph not 55-60!

I have mechanical breakdown insurance with Geico, so they are most likely going to cover my problems. I also have an attorney who is building a case against Mazda for not honoring the warranty and not giving me the time of day to look into a possible engine issue.

On a side note, All Star Mazda of Hempstead NY are a bunch of shady bastards! Joe showed me the spark plugs they "updated" in my car 3 weeks ago. They put 11's all around when the car should have 7's and 9's. He said they were trying to cover up the engine issue by using hotter plugs in order for the car to seem as though it was running pretty ok again. Mazda also did not use geniune Mazda NGK plugs, just regular plugs, so when I came in again after the egine blew, they could use it against me by stating that someone else put plugs in because All Star Mazda is required to use only geniune Mazda parts. And of course void my warranty for something I did not do.

Now tell me if this makes sense; what dealer do you know on the planet earth that is going to UPDATE spark plugs, just to be good guys after 45,000 miles?!!!
It's not an update, there needs to be some issue for Mazda to just say: "ok guys, all of the RX8 owners will receive new plugs free of charge, just because we love our customers so much." spare me the b/s! Please if your reading this Mazda, just do me a favor and tell me to go F**K myself, at least i'd have some respect for you!

I really don't understand why service depts give such a run-around on warranty covered work. As long as it's valid, they get paid for it. I don't know if it's general laziness, lack of concern, or just plain stubborness that the customer can't possibly know anything about their car. I think I have a collapsed motor mount, and I bet when I go in to get new ones they'll be more than happy to help since I have almost 60k miles on the car, and will be paying out of pocket. My parts dept is horrible though, so I might have to wait a month to get them (and that's at the "good" dealership in town). I miss Tom Bush Mazda in Jax.

Hope you get it all worked out.

Cant you take the test results to mazda and prove it to them, and in turn get re-embursed since it should be coverd under warranty anyway?

I assure you this is not the way MNAO wants the dealer body to behave.

Call the Customer Relations folks. Tell them you want to meet with the DCSM and have a true rotary compression test performed. They can still do it with the WDS. We need 3 chambers per rotor and cranking speed plus the difference in high end and low end.

Tell them you want a copy of the test.

I tried to , they said they are irrelevant because the results are not from a certified Mazda service center. Then I called up MNAO and they said the same b/s.

I told MNAO that I wanted them to send a tech to test the car. MNAO exact words; "we cannot do that until the dealer has confirmed that there is an issue". "It is the dealer's discretion if they feel they need to look into a problem".

Oh and they supposedly did a compression test on my car, I have a service write up stating it was performed and this is how it read;
#2 - Customer Reports: C/S CHECK PLUGS AND PERFORM
COMPRESSION TEST.
Work performed by
SPARK PLUGS CHECK OUT FINE AT THIS TIME.
COMPRESSION TEST RESULTS: (NORMAL/AT SPECS).

I spoke to a tech at that dealer and he told me that they would never do a compression test unless MNAO authorized it, or if I paid for the work out of my pocket. The reason being is that All Star Mazda would need to eat the cost unless they had authorization, and to get authorization from MNAO, the dealer would need to state that they think there is an internal issue, and then there is a legitmate reason to run these types of tests.

And of course as you have read the service manager won't address the issue of a possible internal issue.

By the way just for ***** and giggles, when I told the service manager that the issue was very noticable after 6-7k rpms, he then told me that my car redlines only at 6k!!!!

Go to a different dealer, this one obviously is not smart enough to work on cars.

Brice gives good advice here - you need to get to a dealer that will conducted a valid and fully/properly documented compression test on your vehicle before you exit your OEM warranty (no reason to allow one bad shop to cause you to have to deal with the mechanical insurance claim).

I also had my factory motor fail at just about the same miles as you. Also had problems with run-arounds from the regional Mazda rep and MNAO (although my dealership - Werner Mazda in Manchester, NH did everything they could within their limited authority in this situation to make it right by me). Check out the following thread for some hard learned information on my similar scenario. Also, make sure you get the replacement motor (whether reman or new) tested/certified before you take delivery on it post repair.

Depending on Lemon Laws in your region, you may want to be sure you have followed the rules to keep this option open to you as well.

Good Luck!

I can't, they have black-balled me from any other dealers on Long Island, MNAO spoke with the other dealers out here and told them not to accept me for service because All Star Mazda was dealing with the issue. Talk about me getting the run around! This should all be on it's way to being resolved tomorrow after I speak with the attorney and Geico with my findings. I'll keep you guys updated, this should get really interesting.

Then it might be time for a trip off The Island to another town with a reputable dealer that can properly handle your request for service. Any relatives/friends you need to visit in towns near by dealers that have been given good "props" by folks that contribute to this site?

There is something wrong with this story,
1.a dealer does not have to get MNAO 'permission' to do diagnostic work.
2 any parts used on a repair order are shown on the invoice given to the customer.MNAO gets a copy of this in order to pay the dealer.Any parts used or supposed to be used can be traced to the dealer from MNOA parts invoices to the dealer.Putting none standard plugs in an RX-8 could easily be traced and therefore does not make sense.
3 similarly the compression test results will also be part of an invoice submitted to MNAO for warrant payment.(usually the print out from the WDS).This includes all 3 values from each rotor.
Why cover up the dealers name in your first picture?

Oh one other thing---who charges 2.1 hrs to perform a compression check?A job which might take all of 0.75hrs.

That wasn't a dealer I covered the name of it was my name address and phone number.

If Geico won't cover this, then my next step is to go out of state to a dealer who has good feedback from this forum as mentioned earlier in this thread from another member.

The labor actually did take 2hrs. The compression test wasn't the only thing he did, he pulled the plugs to check the rating of them, also double checked a few other things to make sure that the issue was only from the engine not from the clutch, motor mounts, or any other b/s All Star may blame it on.

I have asked for the compression results from All Star Mazda and they refuse to produce anything other than "Normal" as the result of the test. The insist that the tech working on the car did the test and that "Normal" was the only and final result.

I appreciate everyone's feedback and references to other dealers and threads to help me along.

I am glad to be a part of this forum for those reasons and many others. If it wasn't for forums like this, those of us with these dealer issues, would have a harder time than we already have in attempting to get Mazda to do the right thing.

Thanks guys, I'll let you know what happens this week.

You must have seriously pissed someone off...or there is more to this than it appears.

I can't believe that Mazda NA won't let you take it to another dealer if you are dissatisfied with the one you have used in the past?????

I was on the phone with MNAO and the rep. put me on hold because I was insisting on going to another dealer. He was checking with the dealer and his supervisor if I could go somewhere else. When he came back on the line I was told NO, and not to go to any other dealer but All Star because they started the work. I called another dealer to make a appt., when asked for my name and make of the car, they were aware of my situation and told me All Star is where I needed to go.

Well you see, your are right about pissing someone off. I was trying to be nice about the whole thing until I started getting blown off on three different occasions; from the service manager making me take time out of work to go for a ride with him, then when I arrive at the dealer he says, " I have a headache and can't go". "I also cannot send a tech in the car with you because you want to exceed the speed limit to prove there is an issue". He insisted that in 2nd gear I would be doing 80mph at 7k rpms! After that, I told him to his face that he was a bullshit artist. I proceeded to call MNAO and explained my problem. MNAO said they would have a supervisor call me back withing 24-48 hours and I never recieved a call. I'm not going to keep carrying on with the story, you can see where it went... around in circles until I was so fed up after 3-4 weeks that I called an attorney and Geico to see what my other options where.

I also received a call from the asst. service manager's cell phone. He told me that the head service manager was giving me the run around and knew there was an issue with the engine but did not want me in there if possilbe. He also continued to say that the service manager emailed MNAO telling them that I was a young punk kid who raced the car and wanted to do 100mph with him in it. Not in those exact words but along those lines. MNAO denies any of the above, but in all reality, would they tell me anyway?

I'm going to look at the Good dealer/Bad dealer section to see what I can find in NJ or upstate NY.

Look you have to pull 2 plugs to do the compression check anyway,the other 2 would take 1.5 minutes each,you have to work next to the driver's side engine mount to get the plugs,where is the rest of the compression test data?any ROTARY technician would never report a compression test as on your invoice,I have done enough to know.mazda dealers I know would also report full compression data on customer invoices(full data would be 6pressure readings and 2 rpm readings)

you cant compare the results of the compression check done by the mechanic with those from the service manual because they are two completley different tests.

when did this start? MNAO didnt call around to all the dealers and say "dont service Devious' car". But i bet all the long Island Mazda dealers talk to each other. Might even be connected like the Vegas dealers.

dont forget that this forum is a double edged sword. People at MNAO read this and a few other forums looking for issues AND trouble that might be cominn their way. For instance if there was videos of you drag racing or doing huge burnouts they could grab those and use them to deny warrenty claims.

you need to get an accurate compression test done with the correct procedure. check your PMs
