PCV Valve

I think I'm missing a PCV Valve off of my 77 351M if I'm correct it needs to be in the hole on the passenger side on the top of my engine correct? and does it matter which one I purchase? Thanks for your help.

They are really just a check valve, so just so it fits your grommet. Make sure to get 3/8 fuel line to connect to your vacuum source on the carb or intake.

O'Reilly has the correct pcv valve without the second port-that's where I got mine.

Oh, and tell the counter guy you have a 400. There are three different 351s, and that sometimes confuses the counter guys
