Make sure you get the right size.
There was a hissing sound coming from passenger valve cover.My old breather was bad.Installed this on my 305 small block engine and hissing sound stopped.Man what a relief and it looks cool.

Nice looking with a tight grommet.
It fits tightly with the supplied grommet. No worries of water entering when spraying off. It may take a little motor oil to lubricate before installing to make it go in easier.

Perfect Fit!
Fixed my Jeep CJ5 258 I6 valve cover oil leak. Every breather/grommet I tried would seep out oil. This one has a super tight fit, creating a proper seal. if you've got a aftermarket aluminum valve cover, this is the Breather/Grommet for you.
