On the subject of oil pressure delay . . . My MGs have this issue to
some extent, but at least I can monitor engine speed with the choke
knob, and keep RPMs very low until I see the gauge begins showing oil pressure.
I have a '01 Miata with only 18k miles on the car. If it sits for a
few days, and I start it, the engine would race and I could hear all
kinds of rattling going on. I know it's lack of oil pressure causing
this for a few moments. It was a helpless feeling because I couldn't
reduce RPMs since everything is automated. I must have had some kind
of psychic revelation or something, but I figured out a
solution. When I first crank the engine, I hold the gas pedal to the
floor for a few moments and the engine does not fire. Then I crank
the car again but with my foot off the gas pedal. It starts then,
but has had oil pressure build up from the first cranking, because I
don't get the rattling sounds now. Not sure why the engine does not
start with gas pedal to the floor, but I think this procedure will
save my engine from an early demise.
