BNR S4 oil consumption (intermittent white smoke)

[Solarsurge]

The S4 is SUPER sensitive to crank case pressure. It doesn't take much to blow out oil. I would STRONGLY recommend a PCV plate and using Damond's OCC routing diagram pictured here. Also, check your AFRs. If you're running rich, you might see some blue smoke.

why is the check valve on the green path not after the Valve cover ? Since the right occ is vented, the intake could suck air thru the engine by the VC and occ filter ?



Fstrnyou sometimes peoples don't like the oil smell when venting out.
