tappet chest covers please?
My 3rd attempt this year with using the original type cork gaskets has failed once again.
Rightly, or wrongly, I have always had to trim them using a craft knife to fit them into the cover
and have repeatedly had to straighten the cover to achieve a flat surface but still they don't stop
the oil seeping out, usually in the bottom corners.
Any suggestions or full proof methods will be greatly appreciated.
Thank you

Hi Graham, I will share with you what I do, they don't leak when done.
I use the standard cork gasket-untrimmed with the joint cut at an angle at the top of the cover.
The cover is fully degreased.
Put silicone gasket goo round the recess of the cover then put the cork in. Put a tiny bead of silicone onto of the cork.
wipe a tiny bit of oil around the joint face on the block.
Put the cover on gently tighten, leave for 12hrs remove any excess silicone and then "nip up the thumbscrews" do not over tighten.
For me the great thing about this, is that you can at a later stage remove the cover adjust tappets and replace cover as is (do not over tighten).
Incidentally I recommend using dowty washers on the thumbscrew shanks (much better than the useless fibre washers washers).
I hope this is successful for you.
