Sludged up badly. I pulled the valve covers and cleaned all the crankcase vent passages and ports. It seems like it is letting oil accumulate in this area and now, with the ports cleaned up, sucking oil into the intake. Have not gotten far enough into it yet to determine why the oil seems to accumulate in this area. Anyone have any drawings or schematics of how oil is supposed to get back into the crankcase from the ccv section on top of the valve covers? I added some AutoRx to the crankcase in an attempt to clean things up. Whenever I floor it after idling for a short period of time it blows a bunch of oil out the exhaust. It is going to be interesting to see how well the AutoRx cleans it up.

This is my first time dealing with a sludge up engine.
