Oil Pump

For what its worth, I do believe that this level of oil pressure is too low.
The fact that you are not hearing strange and expensive noises makes me
think that your pump is probably flowing a sufficient amount of oil, but the
pressure relief spring has possibly failed. I haven't messed with Flathead
Fords in many years (we raced several V8-60's in midgets over 40 years ago)
and I cannot remember where this is located.

As information we ran 30 weight oil in flatheads on the street and 10 in the
winter. But, in those days, everything ran that weight oil. The race cars
ran 50 weight, but we ran extremely hot as the Offy guys would run slow
starts to overheat the Fords.

Good luck,
Jim Fahlstedt

I would most assuredly switch to a multi-viscosity oil.

The book calls for 40W in the summer, with age I figgure that 50W
can take up the slack. I forgot about the relief valve when I had the
pump out for cleaning - opps.
I have found several pumps on the net, plus a local parts house
that carrys them, to change it without pulling the engine can be done
but is a chore, may as well get the best pump that I can find if I am
going to go through the hassle..
59AB that was in car had 80# cold, 35# hot on road, and 15# hot
idle, had only 9000 miles on it but was wrong engine for car and had a
leak in the block - water in the oil, fixable but since I had to pull
it to fix the leak I changed to an original engine.
Check my page under DeWick Repairs for picture.

Gonna post it here to you Terry, in the exact words a dear friend (and
QuakerState engineer) put it to me.

"If you *really* need 50w then you're *way* past a rebuild, and if you
don't, then what makes better sense.... gettin'em wet from the start, with
whatever you can get there, or leavin' all your cold, heavy oil in the
crankcase and pushin' dry rods?."

I know, you all are about to start dickin the quakerstate, and in some
ways......... i agree (I use Castrol personaly)

but... think about it. what is better. gears, valves, etc somewhat damp
while the engine starts and revs, with lighter oil, or dry parts humping
each other waiting for the heavy oil to get there?

personaly, I don't care if my engine is cooled and lubed with dog piss, as
long as it is cooled and lubed evenly from the time the starter first
strikes, till I cut the fire. I'll take 5W10 for my machines, and piss off
pressure as long as there is enough to push it around.

Your milage may vary.
