Its a 1990 Eclipse turbo. Chances are its very high mileage and the previous owner beat the crap out of it. Most likely the turbo is shot, possibly the bottom end as well.

How can I find out if that's what that is... I'm very low on cash and I have to move my car because I'm moving....what's the best way to stop it from smoking until I can take it apart??

It also has 169,xxx miles on it!!!


Does it smoke all the time or only at start up and or long periods of idling(like waiting at a traffic light)

it starts smokin when i press on the gas... When its idling its smokes a lil bit...it leaks oil as soon as i turn the car on and im not sure where its comin from??


My 91 gt was doing similar and it was a bad pcv valve. Was building up to much crank case pressure causing the oil to be pushed by the valve guide seals( causing it to smoke) and also by the valve cover gaskets( bad oil leak) I would check it first you might get lucky too.

should i buy the book for the car so i can get all the tourque specs?? or is there somewhere i can go online and download it...


Alldatadiy.com will help with info on specs


a quick way to check for turbo failure is by checking for shaft play. there should be no movement whatsoever. smoke on startup and initial accel is likely failing piston rings. do a compression test, record the numbers, then squirt some oil...not wd40, actual engine oil...into the cylinders via the spark plug bores and compression test again. if compression numbers go up by more then just a few points then youve got bad rings. a cylinder leakdown test can tell you where the leak is coming from. google how to do it...its easy and the tools can be bought for cheap at harbor freight.
