This is my first stroker build and I am dialing it in...
The last issue is that it seems I have too much pressure in the crankcase and my PCV valve is not up to the task.
The engine is a 393W with a fairly aggressive hydraulic roller cam. At idle it draws between 12 and 13 inches of vacuum.
I am using a new stock 351W PCV valve... I am beginning to wonder (particularly so after noting the vast difference in initial timing vs a stock engine) if I need to use a different PCV valve. Then again, I have no idea how the PCV valve part number relates to displacement or vacuum.
I realize that part of the issue may be that the rings have not fully seated yet too...
If you are running a 393 or 408 stroker, what did you do for a PCV valve?
Thanks in advance,
