you need a baffle, i's no problem to put baffles in your covers 4speedTerror.


you can go to mr gasket and buy a pcv valve baffle grommet to go in the valve cover. just a matter of drilling a hole . used it a lot of times.

Do they make a pcv valve that does not need a baffle? I have some nice Aluminum Cal Custom valve covers I want to use, but they have no baffles, just oil drippers...?

Thats what my motor use to do. Without those baffles I was pushing oil out of the breathers and all over the headers. I said screw the PCV system and just went with 2 breathers, with baffles underneath them. No more oil in my engine bay, and my oil pan can vent those evil little fumes. TAKE THAT MOTHER NATURE AND THE EPA...lol

I have two moroso breathers, but I thought I would add a pcv valve to one cover. Each cover has two holes in them, one for a breather and one for the oil fill, so no modifications are needed... I wan't to keep my freshly painted engine nice and clean.

duh, I missed the post just above my last one. I guess I need a baffle grommet...
