I have one question (I am in the process of replacing chain and guides on my 2.3-16 1986 car)

The upper side of the timing chain cover is pushing towards the head gasket. It looks to me that when I take the cover off, and later back together, I might get oil leaks there.

And I dont like to change the head gasket just for this.

What is the solution?

Degrease thoroughly, and put it back together with fluid gasket stuff (loctite etc.)?
