I sympathise with Old Dave having had problems that way myself when I first got my 36 tourer and was in the process of overhauling the engine I cut a full reinforcing flange for the sump from 1/16 plate and used a similar thickness rubberised cork gasket and have had no problems.
The main oil leaks on my engine were from the tappet cover and the crankcase/block seal. I fixed the tappet cover by putting a very thick bead of silicone sealant in the groove, having first cleaned up the crappy old gasket, then a further bead of sealant over the top of the old gasket. I then covered a very flat, smooth piece of timber, with cling wrap and pressed the cover down with a piece of steel and let it set. After removing the cling wrap and cleaning up the daggy bits around the edge with a sharp blade, I was left with a lovely flat surface which no longer leaks.
The crankcase join was attacked as per a forum members suggestion (I can’t remember the name) by cleaning around the joint thoroughly with solvents and then applying a bead of the blue stuff around the join. That was 1,500 miles ago and I have not had a leak there since.
I hope this might help someone.
