I had both problems in mine.
Oil pressure would drop in long sweepers. New Armando pan, and problem
went away. (plus removable crossmember and I removed the e-brake cables)
I hooked up the heater, and zero water flow. Then I thought, wait a
minute I live in the South. I don¹t need no heater. It been
disconnected since. I¹d like to have a working heater again - since I
sometimes drive in the cold, but I have too many other higher priority
things to think about.
