ive got a b18c5 in my del sol and im hitting almost 100 psi lower on my inner 2 pistons, we think its a bent valves. hoping i dont have to rebuild the whole motor. anyone run into this before??

 

yeah it is bent valves. any smoke coming out from exhaust pipe? u know like bad piston rings.

 

There have been countless situations where people have been pretty sure of their diagnosis and then begin work, only to find another problem. Run a leakdown test before you make your bent valves assumption official.

 

not consistantly, ive only noticed a little smoke every once and a while

 

yeah do a leakdown test and u will find out what exactly went wrong.
