I know this has been touched on before, and I apologize for bringing it up again, but a search idn't turning up the threads.
Made my first "long-ish" trip (just 50 miles each way) in the '89 yesterday, and at hot idle, I was down to about 10 lbs of oil pressure at the lowest. It would quickly rise to about 30 pounds by 2K rpm, and then would just barely hit 35 pounds to about 2.5K. It hit 38 pounds or so a few times on runs up closer to 3K.
Sound reasonable? Or might a new oil pump keep the pressure closer to or a bit over 40 pounds?
Anyway, the good news is that the truck ran just fine and delivered my fiance, myself, and our new furniture home w/o incident!
