351 efi pcv valve

[bhelbling]

What are you guys doing for a pcv valve on a 351 with efi? I am using a cougar intake mated to a truck lower with a home made adapter, but the truck lower has no provisions for a pcv valve.

I ran into the same issue since my old 302 used a 5.0 EFI lower with the big PCV on the back. Now I'm running an EFI 351W with a truck lower intake. To make it work I put a pcv on the driver's side valve cover connected to a vacuum port on the upper intake manifold and a breather on the passenger side valve cover. Works good that way.

These are the only ones I have handy. There is a pcv located in the driver's side valve cover shown in the first picture, with the hose routed to the back of the upper intake. I don't really have a good picture showing the push-in breather, but it is located on the passenger side valve cover. The engine runs perfect with this setup. Without the passenger side breather it runs like crap.
