[Healeys] Healey Exhaust Manifold Fasteners

[Bob Spidell]

Seems to be an epidemic (or is it pandemic?)  ;)

Norman Nock suggests flat-filing the flanges on the downpipes; I think maybe the 
newer ones might be warped out of the gate (I've done this, didn't help me 
much).  The newer gaskets don't seem too sturdy, either.  I think the next time 
I have the downpipes out I might try to weld a small 'cuff' that extends the 
pipe into the manifold a bit.

BTW, I found I could check/tighten the nuts using a 1/2-inch deep socket on the 
end of two extensions--one 3-inch and one 12-inch--and a 3/8-inch ratchet.  It 
helps if at least one of the extensions is the 'wobbly' kind; e.g.

Then, you can reach the nuts by laying on your back just behind the left front 
wheel and working the extensions and socket up to the exhaust flange nuts.  At 
least you don't have to get out the floor jack and jackstands.  On a recent road 
trip I ended up doing this almost daily.
