I finally got my mark ix our on a successful family trip through the mountains. I do have one question regarding the oil pressure.
The oil pressure is right where it should be almost all the time. The only issue is when going up a long, steep mountain hill which climbs 4000 feet of elevation over a very short distance. The car had no problem maintaining a steady 65 mph up the hill, but I did notice a drop from 40 to just below 35 on my oil pressure gauge during the steepest section. It immediately returned to normal when I began the descent on the other side of the summit. Is the drop in oil pressure something to concern myself with? Why would it do this? The rpms were steady.
Thanks for everyone’s help in getting me this far!
