In the attempt to get my Spitfire back on the road this year, I changed the
oil and filter. As I was pouring oil in, I noticed that oil was pouring out
at the back of the valve cover. Since I have an alloy valve cover, I
ordered a silicon gasket.

Any recommendations as to a sealant to keep the oil inside the valve cover?
Or is that gasket going to be enough?

Regards,
Doug Mitchell
