Thanks in advance for any advice you can render. I have benefited greatly,
as a novice AH restorer, from your past assitance.
I have cleaned and restored the Manifold for my BJ8 engine. The 6 exhaust
manifold bolts for the attachment of the front pipes
are rusted and frozen in place, although all still are their normal lengts.
Threads are shot. I'd guess that heating the manifold
and trying to unscrew then would be mosly unsuccessful.
Do I take this manifold to an expensive machine shop to have the bolts
removed and have the holes
rethreaded to the correct size, or can I cut the bolts off and drill the
holes for a slightly larger straight-through bold. (There seems to
be enough room on the manifold to allow a standard sized bolt head and
washers. (This will not be a concurs restoration.)
Second question out of curiosity. There are two small pheumatic fittings and
two thin tubes that exit the intake manifold and go out
the bottom of the engine. Purpose? Don't they screw up the manifold vacuum?
It sure looks like they're an open 'hole' in the system.
Thanks again, and I'm sure you'll hear from me again as I assemble this pile
of rubble.
