While I have the intake off I'm going to paint
it. What is the original or close enough color of spray paint I might be
able to get from Napa or Kragen's. This in for my 67 Imperial 440.
Thx,
Chris Strohmeyer

Chris, your vacuum leak, could easily be in the crank-case area, (bottom
of port). Look at the bottom of the head intake ports for oil.If they are
oily, your on the right track.The fact that you found no sealer around the
ports, says someone did a "DRY" seal on the intake. That could be your
problem.The fact that your engine only has 30K, means little, since I
just did valve seals, and intake gasket, on my 77-440 52K, which never went
more than 3 months without running. Ya'll have a nice day, Dave

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

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.
