Wow.  This thread has gone far afield.

Forget crankcases.  Forget oil vapor.  Forget H.P. increases.

Use the exhaust bung to SIMPLY create vacuum, regulate it, and use it to
drive your steam gages.  That's it.

IMPORTANT NOTE: This will create TOO MUCH VACUUM.  Something on the
order of 15 psi, if memory serves.  You WILL need to regulate it.

The point was that with this solution, you will not need to worry about
mechanical problems, shearing shafts, pump maintenance, pump weight, and
all the other things that go along with a mechanical solution.

Yes, smog pumps are cheap, but an exhaust bung in cheaper, more
reliable, more durable, less maintenance, and ... LIGHTER.

Vince what do you mean by an "exhaust bung"? Do you have a dwg?

Paul Lamar ...No rotor no motor.

Paul -

No, I don't.  I am googling trying to get something more substantial for
the group to reference.

Again, sorry guys, I cannot find the original, informative article that
I read a few years ago.  If anyone finds it, please, PLEASE post.

Paul, I hope the *actual* parts link (at Mr. Gasket) is better than a
drawing, and will give you an idea of what's required.  (40 bucks, it
looks like, and toss the crankcase stuff.)

I looked at that and I still can't figure out how they welded it into
the collector. I am not going to give them my email address just to
look at the patent. Why they want it is beyond me unless they are going
to sell it to a spammer.
