I just bought a 90 eclipse turbo a few weeks ago..I the original turbo was fried, so replaced it with a big16G. The car ran great for 2 days. Yesterday I was driving normal and all of a sudden the car started spuddering really bad. I went to my friends house to see what was wrong and i noticed oil all in the spark plug wells. So, i replaced the plugs, wires, valve cover gasket and oil cap today and I still have the same problem, its just not as bad. The car hardly stays alive, it sounds like its running on 3 cylinders. What should I check/replace next? Thanks

 

Pull the valve cover back off and replace the seals aroud the holes for the spark plugs. That's where the oil is coming from.

 

i did, it replaced all of the valve cover gaskets..could my ECU be messed up?

 

Do you have a check engine light?
any supporting mods for that turbo?
check for any loose intercooler piping.

 

do a compression test on all cylinders. it might mean a blown head gasket. do you know if the car has had the engine rebuilt? especially since the car has some years on it.

no check engine ligh, stock car...im gonna do a compression check today.

 

car wont even start now, it turns over, but no fire. Im thinking electrical or fuel problem? I still plan on doing a compression test. Any input would be nice. Thanks

 

do you still have oil in the spark plug wells? remove your ECU and check the condition of the CAPS. do you have a datalogger?

 

i dont have oil in the wells anymore. I checked the caps, they looked fine. I dont have a datalogger..HybridAWD is letting me borrow one of his extra CAS's to see if thats the prob. Any other solutions?

 

Do check your caps. What was it idling like before it stopped running?
