VALVE COVER PRESSURE!!!!!
 

I HAVE A SMALL FILTER ON ONE OUTLET OF THE VALVE COVER. AND A RUBBER HOSE RUNNING FROM THE PCV VALVE TO THE INTAKE MANIFOLD. WHEN I RACE AND THE OIL PRESSURE BUILDS ALOT OF OIL SHOOTS OUT OF THE BREATHER I PUT ON THE VALVE COVER, WHAT CAN I DO????? OIL CATCH CAN?

RE: VALVE COVER PRESSURE!!!!!
 

If your pvc valve is in good working , and at top end oil is blowing out, it may be from excessive blow by. how many miles do you have on the engine? ( since overhaul) have you done a compression check lately?The catch can will also work if you can get it to drain back into the engine crank case. Aircraftengines have this feature.
