January 14, 200422 yr What is the normal oil pressure (engine at operating temp) on an 86 with a touch over 100,000 miles on engine, at idle and running down the highway?
January 14, 200422 yr middle of guage, 45 when warm 85+/- when cold, goes down when warmed up 15w40 140,250+miles
January 14, 200422 yr 2500 rpm's should be about 50 give or take a few.. idle should be 10-20... saw those #'s on every soob i have ever had.. ea81's, ea82's.. one with 290k original on it
January 14, 200422 yr The guages are known to be fairly innacurate. Basically if it's somewhere in-between the bottom, and the top, and it increases when your off-idle - then your fine. Good engines will peg the meter when cold, and settle down a bit after warm-up. GD
