Looking for some info on installing rocker cover gaskets so they dont leak.I have not yet used the new rocker cover gaskets because I am still setting this motor up so it runs properly-timing and valve adjustment.How  is anyone installing these gaskets?Are you using sealer on both the cover and the head?What are you using as sealer-silicone?If I need to remove later to readjust valves do I automatically need new gaskets?I put the covers back on with the old gaskets but they are dripping a little because of the volume of oil now going to the valves.l

  

The method I was taught years ago was to clean the rocker covers with petrol, turps, etc, then apply contact cement to both the gasket surface and the rocker cover where the gasket sits.

Let them go off a bit and then press them firmly together.

Don't glue the side of the gasket going against the head.

This will keep the gaskets in place until you want to replace them and will allow you to remove the covers at a late date without having to necessarily replace the gasket.

Hope this helps.

I use a bunch of cloths pins to hold the gasket against the dome cover and glue the gasket to the dome.Usually have to let it set overnite.

Then on the cylinder head side I use Vasoline smeared  on the exposed side of the gasket.

Gasket stays adhered to the dome cover and not to the cylinder head when removing for lifter adjustment.

Has worked great for a bunch of years now with no leaks

X2, kinda. I just use silicone to hold it to the valve cover.

It's also important to ensure that the valve cover has not been warped or over tightened in the past.

I was just posting on this thread and I had the old "Lock-up" problem again.   All I wanted to say was that is the way I do mine but make sure your valve cover isn't warped from over tightening.

Insure that the valve cover gasket flange where the gasket resides is straight and true.  Also make sure that the upper part of the valve cover has not been overtightened in the past and to the point that the top of the covers have warped or pulled down too far.

Tim.  I had a similar lockup or freeze problem on my end.  Took place from 8:20-8:35AM CST.  Is this the same time frame for your problem?

I've used the "double" cork gaskets from NPD (?). Sealed to the covers only - and when seating, I placed them on the deck of my bench saw to utilize the flat milled surface. Clamped (weighted) them down enough to get a solid fit - but not overloaded.

I also found that on the inside of the covers - the gasket sticks out enough to be a "stop ledge" for oil to accumulate on. I figured this is an invitation for a leak - so all around the inside I've place a "fillet" of sealant to allow oil to run right down onto the head  - rather than follow the protruding edges.

Hey Steve!What are you using as a sealant?Must be good if you are exposing directly to hot oil and it still stays in place.
