[TR] Valve Cover

[terryrs at comcast.net]

This is almost too elementary to be possible.  Which is why, of course, it mystifies me!

Chasing the oil leak on the TR3A, I had advice from the list about the potential for distortion of the valve cover.  Particularly likely since I bought it used off E-Bay years ago and it's not correct.  It has one of those threaded holes for the evacuation hose that must go to the intake for reburning, but which I plugged with a ss bolt.

Anyway, today I felt the edges for the first time and find it overlaps the head surface on the dizzy side by three-eights, maybe more, meaning the Justin Wagner seal only partially contacts the head surface.  I don't know if it's fixable.

Two questions:

1)  Is the 3 valve cover narrower than the 4 (or could it be an MGB, something like that?)?

2)  Wife gave me a pressure washer a couple of Christmases ago.  Any recommendations on the soap to use?  Cascade dishwasher?  Carwash?

As usual, thanks everyone!
