How is the best way to replace PVC grommet, on my 350.The intake is off ,I thought I would put A new one in.
Pull the old one out, push the new one in. It's easy with the intake off. The common problem is it can be difficult to get the PCV valve into the hole, and some end up pushing the entire grommet into the valley. That entails a fishing expedition or just leaving it there and getting another one. If the intake is off, I would do both at the same time. Replace the grommet, and then push the valve in BEFORE you install the intake.. Some silicone lubricant wouldn't hurt. http://www.v8buick.com/index.php?threads/grommet-fell-into-manifold-how-screwed-am-i.330435/
