The only reason I'm wanting to change it is because of some stumble issues I'm having. I'm sure these parts are very hard to find. I'm hoping it can be cleaned up and reused once I get it out. Thanks for the info!!It looks a LOT like the original PCV valves on the late 65 and 66 289s, some 390s and some later Fords that were actually sourced from AC / GM. I have an NOS one at home for my car when I next detail my engine, and my son's 289 still has it on there. The original rubber grommets are often so hardened up they won't flex to allow the lip to escape. Look for the AC marking or a C5ZZ or C6ZZ engineering number on it.
Looks OE to me. That's the way the assembly line item looked originally. My photo shows a NOS one for a hipo.
Yeah, the grommet is probably so hard that it won't let go of it.Looks OE to me. That's the way the assembly line item looked originally. My photo shows a NOS one for a hipo.
Might have a cir-clip on the bottom holding the guts together..... you might be able to take it apart and clean it.
Definitely better quality than what you can get today. Should be an engineering number stamped on the OD, when
you get it out of the grommet. Lip on the bottom of the valve is why it isn't coming out of the grommet easily.
