Re: Valve cover bolts backing out
Wouldn’t matter!
I’d use the same procedure. |

silicone and no leaks. My valve covers are the stamped steel cheapies with the load spreader bars, studs and nuts to hold them down. Last edited by MySons68C20; 09-27-2021 at 12:36 PM. Reason: Added info |

https://www.ebay.com/itm/25340318352...id=p5731.m3795 I don't have any photos. As mentioned before I have to use extra thick gaskets because my valve covers make contact with my intake manifold if I use gaskets that are too thin. They are aluminum valve covers. The surface that the gasket is mated to has an extra lip that runs along the edge of the gasket. They are not like the stamped steel valve covers that have a flat mating surface. |

Re: Valve cover bolts backing out
I understand what you are saying but pics of your valve cover would be a big help.

Re: Valve cover bolts backing out
Here are the ones I have except mine have a PCV and oil fill hole. I don't have a photo of the underside to show you what I am talking about.

Re: Valve cover bolts backing out
Also the radius of the corners on my valve covers always seem to be a little tighter than the radius of the gaskets. So the gaskets never quite fit correctly. They always seem to a little bit larger in the corners than the covers

Re: Valve cover bolts backing out
Just a suggestion
Have you used a straight edge to check the valve covers (Flatness).

Re: Valve cover bolts backing out
Here are some photos of how the fel pro cork gasket fits. Also some photos of the lip of my valve cover without gaskets and some photos of how the gaskets that I didn’t like didn’t fit. The mettle strip inside prevents them from tucking inside the lip. If I tuck them inside one corner then they hang out almost past the outside edge of the cover on all sides and none of the bolt holes line up. You can see in the photo the damage done to the old gasket when I tried to install them.

Re: Valve cover bolts backing out
You can also see my home made baffles that I made like in the article. They seem to help keep oil from coming out of the breather.

Re: Valve cover bolts backing out
The pvc needs to be separated from the baffle by a given amount of space. (The directions give the specific amount) then you use the adaptors (simple spacers really) around the shank of the valve in order to back it off from the baffle so as to give it the specified "breathing room ".
