PCV Valve

[WendyB73Mach1]

I have a 351C Q code I’m trouble shooting. Can you tell me where the PCV valve is? A picture would be amazing. I’m experiencing a gas smell from the engine compartment so I’d like to replace anything that may be responsible for this. Thanks!

The valve should be in the oil fill cap on the left valve cover. It should have a formed hose attached. If you smell gas, it is likely a leak at the carburetor or attaching hose section. Chuck

This is my oil fill cap. I’m not sure that I see a valve or is it the entire elbow?

Valve cover on the other side (passenger or left side) will be toward the back of the engine.

You have some custom previous owner work done there. The PCV is likely in the opposite corner on the passenger side valve cover.

Might want to take a look at the fuel tank vent line that connects to the charcoal canister as well.

Here's the PVC valve on a couple of mine. Its just pushed down into the oil cap, on the driver's side valve cover. You just pull it straight out.

For a replacement, I like the ones that come off at 90 degrees like this. I wanna say its a GM part. The original ones for our cars were straight, and used a 90 degree hose. Its a little more compact if you use the PCV valve with its own 90 degree. And if you use a universal one, it may come with 2 ports and a cap that you put on one of them.
