Regarding the oil pressure, don't take that too lightly. You should definitely put in a good oil pressure gauge, like a VDO. I also like their dual sender, that keeps the oil light working and gives you a sender for the new gauge all-in-one.

I would not drive the car if you are getting very low pressures (eg <10psi per 1000RPM, as Dave suggested). I ignored that once on an engine, thinking my gauge was bad (did not have the dual sender set-up, just a cheapy oil pressure gauge) and lived to regret it. Ate a rod bearing in the far curve at Morosso. Lucky I did not do worse, like throw the rod and puncture the case.

Now I run VDO gauges in my old cars, and believe them.

Good luck and welcome to the family!
