04 rx8 engine problem??
 

I need help,u guys/girls think i need a new engine???

I had similar symptoms, but for me it was a blown motor. Do a compression test, to me it looks like theres also a misfire but thats just me.

im dealing with the same problem still not sure what to do.

Well,
At first it sounded like the SSV rattling when the camera was on the engine bay.

But when I heard the exhaust I'm thinking MrHH hit the nail on the head.

Compression test, sounds like another one bites the dust

thank for the help! I will bring it to the dealership to have the compression test on monday. Look like I need a new engine,too bad this car is fun to drive....thank again everyone.....

Don't despair.
We could be wrong.
It's hard to diagnose via the Internet.

Have solace in that a compression test is never a waste of money. That is assuming they do it correctly.

You need 3 readings per rotor, so that is a total of 6 readings.
Those readings need to be normalized to 250 rpm.

Alright thanks for that last part so now Ill know if they even did it right.

update! got a call from dealership,said my rx8 has very low compression n I need a new engine:(

What are you plans now then? Reman engine? It would be a good idea to look at the long term goals for the car. Did u have that 8 year/100,000 mile warranty? Im sure if you posted your location a few of the more experienced members might be able to refer you to some re-builders.

warranty is up:( I am located in Toronto! I might rebuild,hopefully its cheaper then buying a new engine...

Yes, its cheaper than a new one...

It sounds like you are just losing compression, so it is very possible that many of the few engine parts in there could be reusable.

rebuild the engine :) running fine....only problem is I have to replace the front 02 sensor:banghead:

Hey Goku congrats. Did you do a compression test after the rebuild.

Just wanted to ask, where'd you got yours rebuilt from in Toronto and how much did it cost? Thanks

I am going to ask the question because no has asked it. How does your cat look?

rebuild cost about $5600 n compression test was excellent,dealership located in newmarket did the work. replace the cat too!
