I just got my C223 diesel engine that I will be putting in my Trooper a week ago. The engine came out of a 2WD truck and I ask will this 2WD model engine sit into the 4WD Trooper without any clearance problems? I know that there were differences between the C223 in a 2WD and 4WD, being that the oil pan and oil pump are different. If the 2WD engine doesn't work, can I put on a 4WD oil pan and then drop it into the Trooper without clearance problems? I do plan on a 2.5" suspension lift on the Trooper and have heard after you do a lift usually you don't have to worry about the oil pan hitting things. If I were to have to put on a 4WD oil pan, does any member here have one they could sell? Also, the engine I got is froze up because of 2 glow plugs missing and water getting into those holes where the glow plugs screw into the cylinder head. The clutch disc and pressure plate have been taken off, tried to turn the engine with a large wrench but won't turn over. Have put kerosene in it to try to unlock, but what else can I do to free up the engine? Thanks.
