this is a hard one for you guys

ok i have a dohc zc with a t25 turbo and an apexi safc2 with 450cc injectors and an msd 6a box. heres the problem all of this was in an 88 dx civic and i crashed it so i switched everything over to a 90 civic std
no the car sounds like it has a dead cylinder and is smoking bad
also the crankcase filled with gas. i have already put new injectors and spark plugs in and still the same thing any ideas?

what kind of smoke is it? what condition is the new engine in? hows the compression on the new motor?

white smoke some black when i rev
i engine has 40k miles on it
i havent had a compression test on it but it was fine when it was in the other car

white smoke usually means the head gasket is blown, as coolant is leaking into the cylinder. how is your coolant level looking? my guess as to why it seems like there is a dead cylinder, is because there is one. the gasket probably crapped out on you at that cylinder, and you have lost a lot of compression from it. do a leakdown test if possible, but a compression test would help also.

i did a compression test and i got 180psi on all four cylinders the coolent has also been fine

run the car and pull off every spark plug wire one at a time and see if the idle changes at all

i say a bad oil pump causing

with the car running i pulled off each plug wire one buy one and none of them changed it at all
but if i unplug two injectors at the same time it will run better for a few seconds

probably running rich, check your safc
