[Healeys] Rocker cover gasket

[John Spaur]

The silicon gasket is worth it.

 

Use RTV to adhere the cork, or silicon gasket, to the rocker cover. Use non-hardening Hylomar for gasket to block. I did that with both gasket types and did not have any leaks. I currently have a silicon gasket installed. I have removed the valve cover several times in the last ten years and reinstalled it without removing it from the valve cover. I only used Hylomar at the block.

 

I believe the silicon gasket for the alloy cover is flat on both sides because the alloy cover is machined flat, but I am not certain.

 

Also, as other listers have stated, be certain the steel valve cover sets absolutely flat. I had to work the perimeter with metal working tools to flatten it. I also had to twist it so is would rest flat.

Thanks for all the replies.  I'm leaving my cork gasket on for now but will go with silicone when the cork gets old.  The key is using red RTV sealant.  Also the Moss silicone gasket appears to be made by Alexander Racing Enterprises.

I have the excellent Ray Juncal rocker cover with a cork gasket.  I noticed that Moss sells a silicone gasket.   So 2 questions for the list:

1.  Is the silicone gasket worth it?

2.  Moss has 2 versions, one for the original rocker cover and one for "alloy covers". No other explanation.   Anyone have an opinion on which to get?

Thanks.
