Oil leaks

Don't forget to check the crankcase breather and the PVC hose from the PVC valve to the manifold. Do this by running the engine and pulling the hose off the PVC valve and see if it is puling a vacuum. Sometimes the oily vapors will bake on the inside of the hose and eventually plug it up. Also the rubber deteriorates and collapses from the vacuum. That will basically shut off ventilation in the crankcase and the air pumping from the movement of the pistons pressurizes the crankcase and pushes oil out thru the seals.
