I have a newly rebuilt atomic 4 which recently began emitting light oil spray and smoke via the valve cover/crankcase breather. Not sure what exactly the round opening is on the valve cover, but I'm assuming its a crankcase breather. The engine has 90 psi compression and seems to run fine. how much smoke should be coming from the crankcase breather? does anyone have any ideas why it is emitting a light oil spray? The oil pressure is between 20 - 40 psi.
