The rule of thumb is that for every 1000 rpm of engine speed you need an
additional 10 psi. So, for an engine that revs to 5000 rpm, you would need at
least 50 psi at that speed. Now, the question: how is the driver going to
know? When the cars were new, the idiot light was all you needed. If
something was wrong, it would be most likely an oil pump or low oil, both
pretty fatal. So, they installed these idiot lights that are triggered by
pressure below 5 psi or so. Now that the cars aged, you need more than that.
All 60's and many 70's Imperials had oil pressure gages in them (real low
response electrical units with no nymbers on them, just "high" and "low". My
suggestion for all is that if you are in doubt what the oil pressure is up do,
install a mechanical gage.
D^2 (2x68s) that needs to install a mechanical gage on the LeBaron (although
confident the oil pressure is fine)
