Awesome - thanks again!

Thanks Jerry. Good to know the front diff produces that much heat, even when not under load. Guess my pinion nut torque is within acceptable tolerance, else the pinion would be generating much more heat due to excessive friction.

Thank you very much. That does help. Just to clarify, you're saying that with normal highway driving in 2WD, your front differential is generating heat at the pinion comparable with my results, i.e., ambient plus around 40 F? And the rear is ambient plus around 60 F? Thanks again.

I'm Looking for some help on a not-often-asked question after searching without success. Background: I just changed the pinion seal on my Dana 30 front differential and unintentionally placed more torque on the pinion nut than I intended. I'm concerned I may now have too much pre-load on the...

I just performed a compression test on my 2.5 liter TJ (215,000 miles) and I'm looking for clarification regarding the ideal amount of compression cycles to obtain an accurate reading. I'll start by quoting the FSM: 1. Clean the spark plug recesses with compressed air 2. Remove the spark plugs...

So I am ruling out piston skirts. I listened carefully using a stethescope to various locations on the valve cover, timing chain cover, and under the engine to isolate the sound. It seems to me it is eminating from the valve cover area. My best guess is that upon installing the new lifters...

Thanks Gents. Just wanted to post an update. I changed out the oil filter but it did not resolve the issue after driving it for a couple of days. I then drained the oil and fished a small magnet through the oil pan drain hole and swept the bottom of the oil pan (lowest part of the oil system)...

Good advice. I'll postpone the MMO treatment until just before oil change interval. I did, however, just begin adding it to the fuel and will keep an eye on things after several tanks to see if there is any difference. Regarding the possible anti-drainback issue, I have several Mobil One oil...

Thanks Jerry. I suppose it won't hurt to swap out the oil filter to rule out that possibility. Hey, if anyone can answer this I'd appreciate it. Regarding Marvel Mystery Oil, is there any problem adding it to the engine oil now instead of waiting till near the end of the oil change interval...

Thanks much. I did find one loose bolt on the exhaust manifold. All the others were OK. There was no difference in the sound after tightening though. I also removed the valve cover and checked the rocker arms for any play thinking perhaps there was a sticky lifter. The rocker arms were rock...

Regarding the piston skirt issue, that is one that I dread! I understand that pulling the oil pan and looking for broken metal parts is the way to diagnose it. Maybe I should pull the valve cover and check the rocker arms for any play. I suppose it is possible that one of the lifters that I...

Thank you for the replies. Well, regarding the exhaust manifold gasket, I just replaced it also about 500 miles ago. The old one was completely falling apart and the engine sound was unbearable. Nonetheless, I will check the bolts for proper torque. I did torque all the intake and exhaust...

Greetings. I'm looking for some assistance on a new sound. I replaced the lifters about 500 miles ago. I'm not sure if that is related or not to the new sound, but thought I'd mention it. On cold start, it's a loud tapping most noteable underneath the engine. The sound goes away after...
