PCV grommet for '63 401--duplicate


Active Member
Sorry for the duplicate post--I can't see how to delete it.

After being stored in the CA Desert hear for 3 years, the PCV grommet disintegrated in my '63 Riv.

When I got the new grommet at the auto parts store, it does fit the hole in my '63's 401 valve cover, but the inner diameter is too small to accommodate the stock PCV valve.

Can I use a different PCV valve with a smaller inlet?

Or what is the correct PCV grommet to use with the correct PCV vale (which I already have)?

Thanks for any help
