I am chasing an oil leak from the front side cover of my MGB. I have heard you state that the gasket for a side cover should be the one for a MGA which is cork. For the life of me, I can not find a cork one. Who supplies them?
I know both Moss and Engel (Kalamazoo, Michigan) have that thin cork gasket, Moss # 296-370. Use it with Ultra Black or "The Right Stuff," both by Permatex.
Hope this helps.
