Re: Pressure build-up in valve covers

blow by gasses in the crankcase get routed back into the intake, and then gets burned in combustion along with fresh air.

you may have excessive blow-by.....weak piston rings. but with a turbo, you'll get some excessive blow-by, especially when you drive hard.
