Cam cover gasket

Yes,I think turning them would be no problem,it's the splitting and thereafter sizing that I'd struggle with...

A big thumbs up for the Cometic cam cover gasket. It may be a little expensive, but doesn't compress like cork gaskets and is re-useable.

And me.

I fitted one of these last year, & after subsequent hard driving sprinting & high speed track use I have no leaks whatsoever. The only place it is recommended to use any additional sealant is over the 4 cam bore plugs.

I can also recommend the Cometic Cam cover gasket. I have a rare animal in my leak free twin cam, as I am sure Jono will testify. My set up is (1) A clean head and cover, stoned to remove any burrs. (2) Loctite 574 (orange). Apply a light but continuous bead of 574 around the head face and under the "D" plugs. Lightly place "D" plugs and Cometic gasket into place. Apply another continuous bead of 574 and carefully place cam cover into position. Forget about useless Seloc washers, and instead use plain soft copper washers and domed or acorn nuts torqued to 7lb/ft. Incidentally, I used a competition gasket with 574 on my sump, no leaks there either.

Burtons numbers are.
Cam cover gasket FL719COM
Sump gasket FP713KC This is for a 711M block check with Burtons for yours.
I hope this helps

Anyone know where one can get the aluminium D's from?

My guess is you have to make them yourself.

Next time I have access to a lathe it is my top of the job list.

Maybe difficult to machine the little pimple that stops them moving sideways.

To get perfect semi-circles, possibly the best method would be to use square/rectangular aluminium stock and smooth two surfaces, hold them against each other and mount in a 4-jaw chuck and centre on the split between the two pieces of stock. Then cut the rectangular stock into a cylinder with the lathe, then part off appropriate widths, doing the very last cut with a hand saw. ?

Hello everyone,

many thanks for the many posts. I have a week holiday starting tomorrow. I can think then which of the sealing methods described from you I decide.
