When trying to start a freshly rebuilt eng. or a eng.
that has been sitting for a long time, you should
remove the plugs. Then try to start it. Then eng will
spin quite fast. This will help bring up the oil
pressure. Once you see oil pressure, it is safe to put
the plugs back in and try to fire it.
There is also a tool that will work on many cars to
get the oil pressure up the 1st time. You pull the
dist. and stick a long stick, that is made to fit, into
the oil pump. You now attach an electric drill and
spin up the pump that way.
As to the 2" that is probably right. Remember the
pressure is directly related to the eng. rpm. So when
starting the eng. the rpm is usually below a few
hundred rpm - and low pressure. Once the eng. fires
you should be getting 10-20 at idle and about 50-60
at 3000+ rpms.
Hope this helps

Subject: Low Oil Pressure Reading, Plus Four
I recently fired up the engine on the Plus Four I'm restoring. It's
probably
been 4 to 6 months since it was last run. In the past, oil pressure has
been
normal. This time, the gauge needle wouldn't budge. I shut it off right
away and tried starting it again. Still, no oil pressure reading. Then, I
disconnected the oil line leading to the gauge and started the car. Oil was
flowing through the open line, but not at any great rate. Enough to shoot
about 2 or so inches before drooping to the ground. Does it sound like I
have an oil pressure problem, or is the gauge the likely problem? Can
anyone
suggest a fix? I've considered taking the oil pressure relief valve out and
cleaning it, but my ideas peter out at that point. The engine's a fresh
rebuild by someone who knows Morgans very well and the oil level is right up
there.
