It’s been awhile. Decided the easiest way to deal with my broken heater was to vacation the last 3 months of winter away. Time to address some issues now. I smelled oil cooking and discovered my PCV filter was popped out of the valve cover because of a rotted grommet. And wasn’t even connected to the line running to the air filter. New grommet later today, easy fix. My question is how is everyone here running their PCV set up? Stock, catch can, delete, breather filter? Pros and cons? It seems that no one sells that filter canister in the back. Just the valve for up front. I would imagine it must be pretty junked up inside. Does it really even have a purpose?
