Unfortunately I am very anal when it comes to oil leaks. :o

Wondering if anybody has had this problem?

Any fixes , gasket , sealer?

Thanks

Valve cover bolts have been one of the most common oil leak spots since the invention of the over head valve engine. It would be easier to answer knowing what type of valve covers you have since many causes of the leak are specific to the type of valve cover.

According to your sig I will assume they are centerbolt valve covers. There must be a seal of some sort under the bolt head for that purpose.

Pcv working ok?

It would be "unfortunate" if you weren't anal about oil leaks:thumbsup:.

The fastest thing you could do is to get an appropriate size washer and o-ring. Short of that, like Dennis said, they all leak to some degree, again,there is leakage and there is seepage.

Kevin,

I just went in my garage where I have a set of 062 Vortec with stock valve covers on the bench. They do not appear to have any seal under the bolt head or even between the cylinder head and valve cover bolt tube interface.

The bolt holes are blind so I'd say High Tack on the threads probably wont cure the leak.

I did notice that the heads are machined to fit the valve cover bolt tubes (or the tubes are formed to fit the head) seems like a perfect place for an o-ring.

Are your covers stock or after market?

These heads and covers are sitting on my work bench waiting to be port matched so if you need any pictures if them that's no problem.

I am running perimeter bolt MT Aluminum covers on center bolt adapters.

The oil is wicking up the header side bolts.
