The engine loves the new PCV system that I just changed. It definitely couldn't have been venting the pressure correctly. I thought I had a rear main seal leak, but now it seems that it has disappeared b/c there isn't a single drop of oil under the truck. It was probably forcing the oil through the seal. There is also a noise from the engine that has disappeared when driving.

I have the pcv going to the intake right behind the carb in the middle and then the vent on the front of the valve cover is going to the air filter.
