PVC Valve replacement tips? (3 Viewers)

[faalkinaey]

So just placed an order for a new pvc valve and grommet for the 2F as it’s the one tune up bit I have forgotten to replace under my ownership.. looking at other replacement threads here it seems common that the grommet will break and fall into the tube.. any tips on preventing this, I don’t need a 10min job turning into 3 hours.

Almost NEVER need to replace, remove and clean as well as replace grommet. Grommet will be as hard as a rock be careful not to drop pieces into the engine. Soak old PCV in solvent and continue to use. If it is OEM it is a quality piece.

Just be careful prying the PVC valve out. Lots of wiggling.
