[Healeys] Brake reservoir gasket

[Earl Kagna]

Gents:

I had one of these gaskets on my BT7 reservoir for a couple of years - got 
it from NAPA - p/n 675-1210.  Looks identical to the one Moss sells - little 
slit on the top, everything.  I say 'had' because I had a really weird 
experience with it:

The clutch m/cyl. developed a fluid leak.  Believe it of not, what started 
to happen was the fluid in the brake (outer) part of the reservoir dropped. 
Before anyone states the obvious - calls me a 'drongo' - that the reservoir 
outlet pipes were reversed, that was absolutely not the case.  It was 
checked multiple times.  For some reason, somehow, the aftermarket gasket 
caused that to happen.  We're still trying to figure that one out!  (when I 
say 'we', a couple of very knowlegeable British car professional mechanics 
were consulted).

So the clutch master cyl. was repaired with a kit, and the original reervoir 
gasket was re-installed -for now.  This was last fall, and the car has not 
been driven much since.

If any of the list members would care to hazard a guess as to why this would 
have happened, take your best shot - we are totally stumped here.
