PCV valve grommet
I have had no luck finding a PCV valve grommet for my 66 F100 with a 300 straight six. It mounts into my sheet mental valve cover. The old one was so brittle it just disintegrated. It was about 1 3/4” OD if I was to guess. With a 3/4” hole for the PCV valve. I have ordered 3 already and they were all too small.
Anybody have a suggestion as to where to find one?

My 1966 300 uses a 377394-S. 1 52/64" O/D 23/32" I.D (0.7 inches or almost 3/4"). Looks like a few on eBay or try the NOS vendors. Green Sales Company shows they have 56. Or take the part number into the local parts store and see if they can cross reference it. Of course, if you don't have a 1965/66 300 and it's been swapped to a later year or a rebuilt one put in that you're not sure of the year then all bets are off. Or if the valve cover itself has been changed. Buyer beware. Check all information before buying. These are just examples. I can neither confirm nor deny any parts applicability to any vehicle other than my own. All rights reserved.

Thank you very much. I do have a 66 300 with the original 66 valve cover. I went to eBay and had a few choices. One was $6 and others were as high as $50! I ordered the six dollar one today. It looks like exactly what I need.
thank you again,Rich
