I've been looking around for an answer to this question, and can't seem to
find any pertinent data:
What is "normal" oil pressure for a '73 MGB and what steps can be taken
to improve it short of a complete engine rebuild (or are there any worthwhile
steps...) If somebody wants to point me to a resource on the net I'll be
happy to do the looking up myself.
I have a '73 with approx 120k miles on it. Unknown history of any engine
rebuilds. I currently have 10W40 oil in it. When I start it cold it keeps
the oil pressure up around 60psi constantly. After it warms up, it holds
50psi for 3000RPM+, 40psi for 2000RPM, and drops to 15psi (gulp!) or so
(tough to read the guage that low...) when idling around 1000RPM.
Is this normal? Can I improve it by changing to a different weight of oil?
I don't plan to run this car in the winter, so I'm not worried about the
cold weather starting viscosity.
Another question I just thought of - I have a jack for my MG but I'm not
sure it is the correct one. It says Bilstein on the top and has a round
bar that protrudes about 7". This bar seems to fit into the jacking point
on the car, but when I try to raise the car, the top of the jack tries to
embed itself in the door. Am I missing part of the jack or do I have the
wrong one? Is there supposed to be some sort of extension bar?
Thanks,
