<VV> Looking for a Small Oil Leak

[N. Joseph Potts]

One non-obvious place you can get a leak is from the top of the oil-pump
shaft. This shaft passes through the rear extension housing a bit to the
left of the centerline with its end ALMOST flush with the casting. If you
clean this up thoroughly (compressed air) and then fill the depression up
with high-temperature silicone, you might be able to stanch the leak. When I
last had that shaft out, I put it back in with sealer. No leakage.

VVers:

I have a small oil leak coming from somewhere on the top of the block on
my '66/140.  It isn't a big leak, but because of it's location, it does
a pretty good job of dripping onto the fanbelt and then getting picked
up and sprayed all around the engine compartment.

The problem I have is it doesn't leak fast enough for me to be able to
pinpoint the source with certainty, so I thought I would log on and ask
everyone for a few common areas to investigate.

Right now, it looks to me like it's coming from the oil pressure switch
and I've ordered a replacement.  When I replace the switch, I'm also
going to change the oil filters and gaskets, so if those are causing the
trouble, I should get those then, too.  I'm pretty sure it's not coming
from the dipstick or filler cap, because both of those look pretty clean.

Are there any other areas I should look?

Thanks in advance.
