First items to tackle

1. replace engine bay harness (guy who pulled the motor hacked the harness)

2. Replace the front end (current diff has a locked pinion)

3. clean the engine bay

4. rebuild the aw4 and freshin up a 4.0

So today after santa came by with goodies I took 20 mins to inspect the motor for the 91 and to my surprise i found this


#1 Rod bearing


#6 Rod bearing

Ok for the guy's wanting to know if you motor ever has had bottom end work look for the tail tail sign. from the pic i know the main bearings are .30 over and rods are .20 over. If I would have seen this before I retourqed the main caps I could get a date when the work was performed (the back side of the bearings have a date stamp

Ok so everyone else sees what you are showing here, but I don't. I've only build an engine twice and that was years ago. These bearing look new, or nearly so to me.

The bearings have a little wear but still have the original markings from when they were made. No signs of numerous cold starts or dogging ,and best of all a maintained motor
