I have beaten the snot out of this jeep for the short time I've owned it. It has treated me very well, although I wish I new as much about the jeep TJ as I do now. I would spent the extra bucks for a Dana 44 rear axle. I also think the bumper to bumper warranty should go up to 70,000 miles. I think the all the components of the TJ are weak and designed to be cheap and somewhat effective instead of strong and reliable.
I have a 2001 Jeep Wrangler that I love. However, I have experienced very similar problems with my oil pressure. Sometimes at high sustained RPM the pressure goes straight to 80 lbs. While at other times will drop to zero. Have you had any luck in fixing you issue? I can be contacted at davecounselman@trinitywoodbridge.org. Thank you.
