Thanks to all who responded! Looks like I have got some shopping to do.

>Hi Warren,
>Both tappet covers are supposed to have a cup-shaped washer and a rubber
seal
>that fits inside the washer under the bolt. If only the back cover doesn't
have
>one, that's probably because someone used the wrong gasket under the back
>cover. The two gaskets aren't the same--the back one is about half as thin
as
>the front one. Some gasket set manufacturers obviously don't know this
because
>they put two thick gaskets, whether rubber or cork, in their sets.
>I hope this solves your problem.

>Also check make sure that the tappet cover itself is not bent in. It only
calls for the >max of six ft. pound on that bolt. If you put to much
pressure on it the seals squeeze >out around the cover or you dent in the
tappet cover causing a leak at the bolt. the >MGA did not have the rubber
seal that others have told you about nor the cupped >washer. So I add a
LITTLE silicone to the bolt. This should do the trick. The cork >gaskets
seem to be easier to seal in that they do not slide out as easy. The
>neoprene however last longer. Limit the sealer on the gaskets or use none
at all. >Good luck.
