You probably have a bad connecting rod bearing, broken piston, worn piston wrist pin, a bad lifter or rocker arm. You could pull the valve covers to see if anything is broken. The others are in the motor.

The transmission is probably staying in 2nd gear (limp mode) indicating an electronic issue. Your van will have a 4L60-E transmission

Pull engine 1998 GMC safari


Sort of. The engine is attached to a sub-frame that can be lowered away from the body. I strongly suggest leaving this to a professional.

2000 gmc safari no oil pressure but engine will run


Hi, you could do a manual oil pressure test with a guage screwed into an access port, to verify oil pressure, but if it runs, does not tick, or knock, you may have a bad sending unit, mounted below the distributor, at the rear of the engine. Good luck...
