I have a 1991 GMC 2500 and it leaks oil out of the oil pan but it only seems to do it when it is off after its has been running. It is a two wheel drive and i was wondering if anyone has changed an oil pan and if so how hard it is. Did you have to lift the engine or can you wiggle it out. Im just trying to do some research before I actually rip it apart.
