Need to change oil pan gasket in a 1998 GMC Jimmy 2 wheel dr 4.3

On many vehicles the exhaust runs under the oil pan, on others there may have a cross member in the way, or brackets that will hinder oil pan removal. These parts need to be removed. The exhaust nuts/bolts will most likely be rusted. It is best to spray them with penetrating oil. You can use WD-40, PB Blaster, Deep Creep, or something similar. After you have sprayed all of the nuts/bolts, let the penetrating oil soak in for about 10 minutes. Now remove the exhaust pipe that runs under the oil pan. The catalytic converter may, or may not be in the piece that you have to remove. If you have to remove a cross member, simply unbolt it and set it to the side, it is best to mark which side is the front, as some will only go on one way. Other than that, you should not have to pull the engine at all.
