No PCV valve?
Have you ever run the engine without the valve covers on to adjust the valves? How much
oil is in the heads? Does the
oil drain back to the crankcase quickly?
Our engines are nothing more than an air pump and if the crankcase is not under a certain amount of vacum all that
oil spashing around. Positive Crankcase Ventilation
Do the breathers have a wire mesh under them to filter out the oil?
I am sorry for all the questions but I have been thru this before.
I hated to see even a drop of oil anywhere.
