Engine Mechanical problem
1989 Jeep Cherokee 6 cyl Two Wheel Drive Automatic 200000 miles
I am replaceing the connecting rod bearings, piston rings and had the head rebuilt. When I went to torque down the rod bearings I could not turn the crank shaft. The motor is still in the jeep. I loosened all the main bearings and made sure the jeep was in nuetral and still will not turn. I checked my cam and it moves freely. All the electricals are disconnected. Is there any thing electrical that can be holding it? Or is there something machanical that could be stopping me.
