Have aftermarket rear seal. After having a Healey specialist I know look at
it he seems to feel oil leaking from my valve cover is being blown around
the engine bay. Ill replace the gasket this weekend and seal it with the
Right Stuff sealant. Clean  it and sed if things improve. Thanks all fir
your comments. Drove it to Summer School today. The kids and staff loved it.
