I have a set of the DeTomaso cast aluminum valve covers that require a spin in breather. My car has a throttlebody EFI system and K&N air cleaner assembly. I've searched around and am stumped on what I need to do to get the PCV valve to fit in the valve cover. Can any of you tell me what you have done to solve this? Does anyone make a PCV that fits the spin in valve covers or is ther an adapter I need?

There is a rubber grommet made for that application, it is designed to twist into the valve cover similar to a breather; the grommet has a hole in the middle that you slip the PCV valve into.

You'll find them at a parts house that stocks parts for Boss 302 & Boss 351. Perogie Enterprises normally has them.
Well, Now I seem to have run into another problem. I can't seem to find a breather that works with the cast valve covers. The old breather I had and a new Ford racing version don't work. The issue is that the internal ramp hieght of the cast valve covers is taller than the original steel valve covers. Trying to twist the breather into place results in bending the tang on the bottom and galling up the aluminum ramps.

Any ideas?
