Smoking
 
Changed head in march ran good for 3 days, then the car started smoking again. Did compression test all cylinders were 185. Did a leakdown test and the results were
cyl1: 14%
cyl2:14%
cyl3:23% hissing coming from exhaust
cyl4:23% hissing coming frrom intake manifold. removed vacuum line

Car does not smoke on startup, car smokes blusih-white when in boost.

Help me or buy my car!lol

you prob toasted some valves and blew the oring in the turbo. Or best case scenaro is that your blow turbo allowed oil to accumulate on the valves preventing them from sealing pulling the head is a quick way to see exactly what is up.

I did that and also bent a rod because the oil hydro locked the motor a bit. My compression test was good until I got to cyl#4 80psi.

I think im gonna take the turbo off and put a header on to see what the problem is and go from there....now only if i can find a 1.8 header..

monumentally bad idea to drive a car you know is fucked you could fuck the block as well if you havent already and then you have a 1995 paper weight.
