[QUOTE="Genesiss, post: 444077, member: 22628"] The speedometer definitely needs adjustment but the gear ratio is at 3.72 and needs 5.38 for 37 tires on an automatic. The bigger problem is the oil pressure is way over 100psi when I connected a gauge to the oil pressure sending unit port. It maxed out my oil pressure gauge to what I assume is about 130psi as it buried the needle at initial turn over and 1000 rpm. I didn’t have any signs of damage or leaks or smoke so far. It’s a new rebuilt engine which could be higher psi initially but not this high. What I am gathering is something is blocked, maybe a return hole on the gasket or a blocked oil passage or bad relief valve. I sent a rather irate email to aamco since it’s the weekend over sending me home with the jeep and this issue on a rebuilt newly installed engine. Hopefully no damage yet to the seals but now it’s got to be towed back to the garage. [/QUOTE]
