Hi All,

One day the car was running fine, the next day I started it and I smoked out my neighborhood. (Note: There is so much smoke coming out of the exhaust, I would only be able to drive 1 mile before being pulled over by the police for various offenses (assuming they could catch me through the smoke screen I'd be leaving.)) Aside from the smoke, the car seems to idle fine. I haven't tried to drive it due to the amount of smoke, so I don't know how it would perform under load.

I did a compression test several months ago (prior to the incident) and the readings were about 80psi.

I'm trying to determine if the smoke is caused by burning fuel or coolant. I am leaning toward fuel.

Pulling out the plugs - they are wet with what seems to be fuel. I cleaned up the plugs, rotor, cap, etc. and verified that the MAF, TPS are working properly.

Does anyone have suggestions for how to diagnose further? I am wondering if I should just replace the fuel injectors (assuming they are just blasting fuel into the intake) or should I do further diagnostics? Any advice will be welcomed.

This is my daughter's car. I am new to rotary engines, but am extremely comfortable working on cars for I have been rebuilding/fixing my own cars for 30 years.

Boy, I really like my newer cars with OBD-II.

Thanks in advance,
Anthony

Update. I did a compression test. 85 front rotor, and 80 rear rotor.

How many miles are on your rx7. The oil seals "in the engine" tend to go bad. Your oil seals are leaking to much oil into the engine. There is one positive to this though. Even though its using an excessive amount of oil, rotarys love oil. The more oil the better really its just the smoke factor. One thing you dont ahve to worry about is damage to the internals if your burning to much oil. The more oil the more the excentric shaft and rotors are lubed up. My 13b has 60800miles on it and the oil seals are starting to go. So it just depends on the age. The only way to fix it is to open up the engine and install new seals. You might as well rebuild the engine as long as its out of the car.:smokin:
