Default 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.

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.
