Interestingly the tube came out of the old pump easily but was tight going into the new one. Yes, I primed it through the OPDA. It took a little while but once it primed it took some torque. I had the valve cover off so I was able to watch all the oil run up through the lifters. Working well...

By "get the numbers" do you mean plastigauge the clearance? I was visually impressed at how good the RM bearing surface was. Only disappointing item I found was the amount of sludge in the oil pan. Really caked on in the bottom. I got that all cleaned up now and I suppose that's normal for 130k.

How tight is the press supposed to be? I ordered a new pump. While waiting for it to come, I pulled the old one off. The tube came out of the old pump easily. I also looked at the service manual to understand the "priming" process. I could find anything in there. Just said bolt up the new one...

Thanks! I saw that post and ordered last night. What would you recommend for the cat back?

Well it turns out it was the PCM and the catalytic converter. Mark helped me a lot with the PCM replacement which got the 4wd and axle lockers working. Once the new PCM was running, it flagged P0421 & P0431 for low catalyst efficiency. Haven't had a chance to replace them. This turned out to...

Thanks. I replaced O2's with NTK. I'm thinking PCM but was looking for a way to confirm for sure it is the PCM.

Thanks for the replies. New to the group here and appreciate the feedback. This is a 2005 LJR. 138k miles. I know very little about the maintenance history of this vehicle. I will go ahead and start a new thread with all the details. I listed the 4wd issue because my understanding is the PCM...

I have this same issue with all 4x O2 sensors throwing the heater codes on my LJR. P0135, P0155, P0141 and P0161. I just got this Jeep. The previous owner just replaced the battery prior to selling to me. I replaced Bank 1 pre and post Cat O2 sensors but didn't change anything. I have chased the...
