brand new h/c 360, dipstick popping out and spraying oil
Most of the pressure in the crankcase is vented through the fresh air hose that goes from the tb to the valve cover since one of the jobs of the pcv valve is to restrict flow. And the pcv never puts the crankcase in vacuum, it just pulls fresh air from the tb into the passenger side valve cover to replace the air that was pulled out of the crankcase.
well i cleaned the air filter and took it out and drove it hard for a couple cycles. still the same. there is no oil going into the intake and performance is great. i also took off the oil fill cap while the car was running and no oil puffed out, so therefore i guess the rings r good. i have pro comp magnum 1.6 roller rockers with stock valve covers with the inside braces and baffles modified so the rockers would fit. my question is would the valve covers be the problem such as a broke baffle or something. i still havent done a leak down test but its coming this week. any thoughts? thanks alot
Is it possible you crimped the baffle for the vent line in the passenger side valve cover closed?
And not to quibble.. but the only way air will move from the front of the throttle body, through the line to the valve cover, into the crankcase, and out through the PCV valve is if the PCV valve is at a lower pressure than the starting point in front of the throttle blades. Since that point is always lower than atmospheric pressure, there has to be a vacuum in the crankcase for the air to move there.... flow only occurs when there is a pressure difference.
