I am trying to find and replace the grommets(?) that the PCV and the Air Intake go into on my valve cover as I have some oil leaking from them and end up with a very small puddle on the driveway some days. I have a 78 Chevette, 180 automatic and not having a lot of luck finding the right ones. If anyone knows what part numbers I should be looking for that would be a big help! Also on the oil leak I am replacing my valve cover and head gaskets as I know some oil is coming from there as well and figured Ii would replace the grommets as well since there is some leaking from them and I will have things opened up so might as well.
