Black Smoke from BOV only

skim7x · 05-03-2015, 06:17 PM

I took my car to the dyno last Friday and found out that I'm getting huge clouds of black smoke from the BOV each time it goes off. No smoke from the exhaust... I have a BMS catch can that collects some oil that I empty out every 6 months or so. PCV valve replacement time? Or could it be my turbo's going out?

Going to be replacing PCV valve... anything else I should just change while I'm doing it? PCV cap? Valve cover? Gasket?
