If the engine had the new modified seal installed, it was removed and was
dry, then from where does the oil come that is entering the bell housing.
It must be coming from above the crankshaft. Where is the leak is the
question? Maybe that tiny little gasket material going around the engine
plate is not sufficient?

Bob, My understanding is that they are two different things, the rear main
oil seal kit is one thing and the gasket for the rear plate is another. I
would not expect the MOSS kit would not have the rear plate gasket.
The parts diagrams shows there is only one gasket between the block and the
rear engine plate. I do not think there is any additional gasket for a "cam
drain".

Subject: [Healeys] where does the oil leak begin if the crank seal and the
new seal are not the cause
Listeners:
It has been explained by some members of this group that the rear Mounting
Plate Gasket in the Moss kit is not sufficient to contain the oil back of
the camshaft drain. Now I am not knowledgeable on the conditions of the
rear mount plate and the gasket, However, John Rowe after 10 years of living
with oil leaks even with the modified seal installed, removed the trans,
flywheel, mounting plate etc, and found it dry. Let us review what he did
find.
I fitted the modified seal 10 years ago and have always had an oil leak
since. After finally removing the gearbox for repair last month I removed
flywheel etc to have a look at it. I removed the backing plate and no leaks
were identified around the seal, it was totally dry. However, the back of
the camshaft drain was a different scenario. I then noticed there should
have been a gasket according to the books, which mine did not have. I had
used a silicone gasket maker in that area and that failed (didn't work). I
made a thick 1.6mm (1/16inch) gasket and now think I have solved the leaks
problem
Bob, The gasket I made only had a 'cutout' for the crankshaft itself. The
remainder covered the back of the camshaft opening, which runs down to drain
back into the block. It looks like an inverted teardrop.
It covers the whole machined area of the rear of the block. I put permatex
sealant all over the flat machined area especially around the camshaft
opening. This was done with the engine in- situ while the gearbox was
removed, quite easy but heavy.
What say you to those who are familiar with the rear of the engine, the rear
plate, and the overall rear mounting plate gasket. Is there are missing
gasket in the Moss Kit? Was there ever a gasket for the area? Should the
rear plate gasket be redesigned to include more coverage? Should we just
forget about the Moss gasket and construct gasket as John had done to solve
the oil leaks forever.
The reason I ask this of the Group, I will next fall have to remove the
trans etc. to install a new clutch plate and want to be prepared to do
something to stop the leaking of oil even thought the installation of PVC
system has greatly reduced the volume.
