Slant Six Oil light coming on — need a new pump?

^^^ Yep all above!!!!!
I have had many slants and many various old Mopars. A lot of slants were not well taken care of, as in oil changes and thus huge amounts of sludge can be found in the pan, and oil mist be moved thru the engine! clogged up pickup, passages, clogged up everywhere? I have mopre than a few like RRR's!
Then there is the cooling system!!!!
I also always pull the gas tank to see if clean and if the pickup still has its sock filter.
I like to add a mechanical oil pressure gauge. That way I can always see what the pressure is showing. I like a mechanical temp gauge and a volt gauge. Just 3 small gauges I add under the dash> There are reasons the idiot light s on the dash are called such!!! :thumbsup: ( Sarcastic humor!!! :BangHead:Cheap gauges because, well, I am cheap!!!!
