What is the hole for and should it be covered with the clip? | | | | | Joined: Mar 2002 Posts: 9,115 'Bolter | | 'Bolter Joined: Mar 2002 Posts: 9,115 | The hole is there to stop the tube from siphoning and the clip is there to stop dirt from getting in. This is described in a GM document, I just don't know which one it is in. | | | | | Joined: Aug 2005 Posts: 6,377 Ex Hall Monitor | | Ex Hall Monitor Joined: Aug 2005 Posts: 6,377 | I'm not picturing what you're talking about. I don't recall a clip with a hole under it. Do you have a photo? How to post a photo.

You also want to keep it positioned so as to deflect the oil that'll eventually squirt out back down towards the head. The oil can squirt straight out of the center valve cover vent slot if not deflected by that clip. Been there done that LOL.
