Backpressure problem maybe? Options

[CaliJeff]

So out of my pcv valve, my catch can has caught an enormous amount of oil/gases and has nearly filled up in just 2 days. out of the top of the lil valve next to the tb, on top of the valve cover next to cylinder 4, gases are coming out of that as well. anybody kno wat is goin on ?

also, earlier this morning, my exhaust was blowing out a lot of smoke, couldnt tell what color it was.

spec is 178 PSI (or more) on all cylinders, a minimum of 142 PSI, and no greater than a 14 PSI difference across the cylinders. but blown piston rings aren't the only reason for low compression. could be loose spark plugs, blown head gasket, stuck or bent valve, etc.

if you don't have a compression checker, I've got a friend who does that would probably let me borrow it.
