<VV> Loose top cover bolts

[Mark Durham]

I'm with Frank on this one. No extra parts that could fall into the
internals.
I use the original gaskets with a thin film of high temp permatex and
the shake proof bolts. They don't hurt the top cover that bad at 7-13
ft lbs of torque! Mark Durham

I've seen this done (trim baffle to fit inside) but never wanted to add
more nuts to fall off into the crank area.

It is faster to just put it back together like GM made it, even dealing
with the hard stuck on gaskets.

Of course it is even faster and cheaper to just use a gasket substitute
like "Right Stuff"  or a Permatex  product.

Isn't that what Smitty was saying?

Those two gaskets are so thin, they don't seem to shrink, just get hard
with time. The thickness of the valve cover gasket is waaayy more than
twice the combined thickness of these two gaskets. Properly installed
(another subject) valve cover gaskets seal a long time. And with only
four fasteners!

"screws won't loosen": What? Maybe if you use Locktite or lockwashers...
and proper torque, yada yada yada

Like I was saying, I don't want to add hardware that can loosen to the
inside of the engine. At least on the outside it just leaks oil when the
hardware loosens....
