My 93 JDM FD smokes heavily on decel only, from my research its my oil seals. My engine has no other problems and runs strong. I know that the engine has to be disassembled to replace the seals, but I am not able to afford it at the moment. I dont mind the oil consumption, its just the embarrasing smoke. Is there anything I could do to minimise it? Mabe thicker oil?



What I have been doing that helps, is to mash the clutch if decelerating from high RPMs to alow the engine to idle as the car slows.



It seems to be high vacum conditions (decel from high rpm) that sucks the oil leaked from the bad seals into the cumbustion chamber causing smoke. I think that if I could find some way to reduce vacum levels on decel, it would help.



What are your thoughts.

 

in short there is no cure except to rebuild the engine, no way around it. are you 100 percent sure its the engine and not the turbo correct? because if your car is higher in milage your turbos are a very likely culprit.

 

leaking turbos gave me the same symptoms... make sure its not your turbos before rebuilding the motor....

 

I agree with these guys on more likely culprit to be the turbos. Apply the same theory to your turbos and they would seep the majority of the oil under deceleration as the exhaust preasure and boost preasure while accelerating would hold the oil in the center section. Just a thought
