Well it happened! On the way home from work today, was cruising up I 380 and my Jeep started to shake. Started losing power and realized that something was going on. The thing still ran and I had oil pressure so I continued on. When I got closer to home I pulled over and checked it out. Leaking alot of oil and smoking, but it still ran, albiet on five cylinders. started tearing into motor, but with temps at zero said the heck with it and headed home. Don't know the damage yet, but it looks like it burned up a valve and maybe took out a piston. Wondering if anyone knew where to get a factory rebuild besides Pep Boys. Tried there with my '84 Xj and it was a piece of crap motor. Thanks in advance, Bob
