Perfect fit on LS valve covers
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.

Its a geomet and it did its job at keeping the pcv valve in place.

Holden LS1 owners, this is for you.
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.
