[Mgs] manifold vacuum

[Max Heim]

The problem with manifold sealing is usually due to unequal clamping force,
because of the way the washers are trying to hold down both the exhaust and
intake flanges. It doesn't work unless the flanges are precisely the same
thickness. Any mixing-and-matching of parts can cause a sealing problem.
Either precise shimming, or a little machine work, is called for.

Stripped studs or nuts can also be a problem, but you'd probably have
noticed that.
