Crud in PCV breather cap

[BRetty]

Today I learned that GMSB is the hottest place on the Internet to discuss PCV valves and vacuum leaks...but I am still puzzled here.

My breather cap on the pass side valve cover had a bunch of pasty, oily sludge up inside it. You can see it oozing out in this pic:

So is this trapped oil and grit from the valves and crankcase? Odd, since air should be flowing the other way. Or is this the oily remains of a sponge/filter element?

Either way, I will clean it out, and get a new breather and PCV valve tomorrow. But if oil has been blowing out through the breather, I have some other problems.

Thanks,
BR

You could be right with your last statement. The PCV system is no match for an engine with blow-by. Might be time for compression and cylinder leak down tests.

There should be baffles in the valve cover under the breather element and the pcv valve.
