[Fot] Valve cover gasket sealant

[yellow04]

I did the same as Tony with one of the widely available cast aluminum 
valve covers for the TR3/4. Had my machinist cut a groove and I stuffed 
a long o-ring in. I'd bet that was 15+ years ago, never had to replace 
the o-ring and it seals perfectly after countless on/offs. On the 6 
cylinder, I use the stock cork valve cover gasket glued to a cast 
aluminium valve cover, works perfectly as well.

I do like the silicone valve cover gaskets on stock valve covers that do 
not appreciate being torqued excessively.

I'm using neoprene o ring seals in some new billet valve covers that 
I've had made and they are absolutely terrific, reseal nicely after 
multiple on / offs and no muck to get down the push rod tubes etc. I 
think that's the way forward.
