Used this on my 5.3 valve cover (drivers side) after fixing the oil passage in the valve cover. Added a new PCV valve and replaced this associated grommet over the old, dry and baked factory piece. Worked perfectly.

Had a vacuum leak on my 01 tahoe 5.3l and couldn't find it so I just replaced every one and no more leaks. I have the old school valve covers that is known to cause problems. It fixed my problem at this time. Was thinking to upgrading them.

This was perfect for my friend's 2001 Chevy Silverado 4.8L LS and the fit for the PCV Valve was nice and tight.

It went in pretty easy and seals the PVC valve.

For those with a failed PCV valve, Holden do not sell this part separately, and recommend instead that you replace it along with the rocker cover as a complete assembly. This is the grommet you need, and you'll most likely find that your new PCV valve fits into this much more snugly than the original.
