Hi
i just put on a reman cylender head, and every thing went fine.I notice a littel blow by coming from the pipe that the pvc plug in to. Its expected 120.000 miles. Drove the car for about 400 miles. And now I have alot of blow by, I did a compretion test, and there all good, no smoking out of tail pipe, no oil on plugs. But alot of oil coming out of the vent on valve cover hose that gose to the air clearner. Can there be some thing wrong with the reman head? Or do I need to do the rings. My head herts from thing of what can it be? Oh I did block off egr pipe thinking it mite be blowing back thourgh the intake, but same thing. HELP ME
Thanks

Check the PCV valve is not stuck? If you are not getting oil on plug's and good compression the ring's are ok

POSITIVE CRANKCASE VENTILATION (PCV)
PCV system uses intake manifold vacuum to recycle blow-by vapors from the crankcase to the combustion chamber, where they are burned. PCV valve meters flow of blow-by vapors, according to manifold vacuum.
When high amounts of blow-by gases are produced (such as worn piston rings), excess gases flow back through crankcase vent hose into the air inlet and are burned during normal combustion.E PCV vlave is not stuck closed?
