I'm trying to remove the oil pan to replace the gasket. I have removed all the oil pan bottom & side bolts, the starter, the engine mount, the trans axle mount, disconnected the exhaust pipe from the rear of the engine, and removed the a/c compressor bolts. I have the engine on a hoist to support it, but I still can't get clearance underneath to remove the pan. The sub frame is in the way & I can't get the right angle to remove the pan.
Do you
have the same problem?
