Ok folks so I noticed the previous owner had the v belt for the Balancer, Water Pump & Alternator on the middle groove and it chewed it up real bad so replaced that today and noticed that the engine mount was loose. See attached.

I have tightened it and wondering what torque spec it should be at and should this have loctite on it?

Gee, that is a nylon locknut. It should not need anything to stay tight. Tighten it well and see if it stays tight. If not replace it.

I found the pulleys got rusty and the rust chewed up the belts pretty good. I would sand them smooth, prime and paint them and the belts would last.

Ayuh,...... No loctite, just good, 'n snug,..... 40ft.lbs. with my calibrated elbow,.....

Thanks Bondo, should I replace the nut? If so what size would it be?

Naw, just snug it down,....

Next time you pull the drive, you really should check the alignment though,....
