[Healeys] Engine mounting plate gasket

[john spaur]

I have noticed the gaskets on the healey vary in thickness from 
almost paper thin to medium and then thick; however I am not meaning 
as thick as cork in this instance.

I had a somewhat medium thick gasket fail at the rear mounting plate 
below the cam oil return. I was going to install a slightly thicker 
gasket but now I am thinking a very thin gasket much like the ones at 
the rear hub should be used. The Moss catalog does not list the 
gasket so I will cut one out.

What thickness of gasket material should I use for between the rear 
mounting plate and engine?

Thank you,
