Thx Dave,
Mmm, there is oily areas around the intake ports
that mystified me. Also, it appears there was no sealer used. My car
didn't smoke at all, it has 30k on it but ran erratically so maybe this is the
problem or the carb which I already had rebuilt and double checked. This
possible intake leak is all that's left.
Thx again

Subject: Re: IML: 440 intake leak?
Chris, the valley pan gasket, is a one time "crush" type gasket. After
years of engine heat- cool cycles, and the bolts loosing torque, intake leaks
are not un-common, sometimes it permits oil to be sucked in from the bottom of
the intake ports, adding to excessive oil consumption.The factory sealer on
the intake was PERMATEX AVIATION gasket sealer, and PERMATEX #2 in the
corners, and bolt threads.I still seal intakes the same way.Sometimes after a
rebuild, or valve job, the heads maybe resurfaced, then the intake will not
seat at the proper angle, the intake must also be machined to maintain the
proper angles.If your engine is stock, then a gasket, and re-seal should do
it. Just be sure gasket surfaces, are clean, clean, clean! One final note, I
don't like silicone sealers, most times it is over applied,it doesn't seal to
oily surfaces, and falls off inside the engine, then it ends up in the
oil pick-up screen adding to the restrictions.Ya'll have a nice day,
Dave.
