Ok,... that was easy. I found the pcv valve right away,... I disconnected the hose from it and removed the valve. I noticed oil on the end of the hose. The was oil in the hose too. I cleaned out the hose before reinstalling it,.... I boiled it to get it really clean

So anyways,... I removed the pcv valve and shook it. I could here it click so it wasn't completely clogged but it wasn't clicking all that well,... there some some crap in there. So,... I used some air intake cleaner and blasted the inside of it unitl it ran clean. I took the air compressor to it too. By time I was down,... brand new pcv valve. It was really clean. Anyways,... I noticed that the hose went from the valve to the manifold,... I dont quite understand how the valve works. We want the crankcase to be under a vaccum right? So that oil doesnt get pushed pass the rings right? Im gussing that the manifold is pressurising the head and the cylinders so that the pressure exceeds any pressure within the crank case so that the oil cant push its way though the rings? Is that right? Can someone explain that to me,...
