Yepper. Just dropped the pan on Sunday to put what my machinist calls a "***ish Knurl" on one of the mains, reinstalled the bearing, and all back together. I had to do that as my crank had too much endplay/thrust.

New to forum
I am a new dodge ram owner. Just purchased a 1997. Love the truck so far and this forum has been extremely helpful in resolving a few minor issues. One that I did not notice until the limited warranty was up involved the temp. gauge. I have attached a screen shot. I was not sure what a normal temperature was until I found this thread. When I turn on the heater it does drop, but this was a picture of the gauge during highway driving. I have noted a ton of ideas in this thread, but was look for a place to start. The truck does not run rough and the only issue within the engine compartment I have noticed is that there appears to be a small leak in one of the transmission lines...
Thanks.

^^Actually, have the timing checked. After going round and round and round and round, my engine guy got in touch with someone who can scan my truck's computer to see if it's in time. After explaining all of the symptoms and when this occurs (under load, hills, etc) that's what we've deduced. I tried to get in last week and it didn't work. Hopefully, I can get in this week to get the timing checked.

The thermostat doesn't regulate a cooler temp. It maintains a minimum temp. If you are over heating beyond the rating of your thermostat, it won't matter how low of a temp thermstat you put in. The only difference would be the point that it opens.

Yesterday, I finally got the truck to a mechanic recommended by a friend. He connected his scan tool to the diagnostic port and checked it. The timing is set at 19.3'. He tried to retard the timing by adjusting the distributor but there was no affect. He reviewed his material regarding the Dodge and *WHOOPS*, the timing cannot be adjusted. Set the engine to 0' and the PCM takes over. I've been trying to explain that to my engine guy for months to no avail. Looks like I'll have more ammo next time I see him.
So, it appears that I have a faulty PCM. JJ is going to check with a buddy of his who he states is the top Dodge technician in the State. He's going to ask if it's possible to reprogram the PCM, get a new PCM, or get a rebuilt unit. This all makes sense to me as the truck was running hot when I first bought it and drove it for approximately 8K miles.
More to follow, but I'm finally on the right track.

We'll see what Mr Dodge expert suggests.
