Can crankcase pressure affect oil pressure?
We’ll look at just a few simple ideas that may help reduce this windage issue. Over filling an engine’s crankcase can cause a loss of oil control and major increase in oil consumption when the oil- and second-rings become overworked and begin to let oil into the combustion chamber.
Can a high crankcase pressure cause an oil leak?
Manuals can be found at the manufacturers website.** An abnormally high crankcase pressure can cause oil leaks. The engine crankcase is designed to operate below atmospheric pressure, and the breather valve or pcv (positive crankcase ventilation) valve is the device used to keep crankcase pressure below atmospheric pressure.
