I have 93 deville 4.9 and im changing the oil pan gasket and pump. i already took off all the bolts and the pan is loose but has a real tight fit to bring it down and off. so far i tried to jack it up from the tranny to give me more room but no help. i used my engine hoist to lift it up evenly a little and still no clearance. im getting fustrated and cant get it out.does any know any trick or know of any steps to get this sucker out.My next step if no advice is to loose all motor mounts and remove axles and pull it up a little further.pls help. thks

 

Getting pan out it tough but it will come out.You may need to pry on it a little to get it past bell housing. The oil pan where the studs go, you can grind an 1/8" off where pan dipples out. Being your are going to replace oil pump you don't have to worry about breaking oil pump taking pan out. Be sure to install o ring on pump where tube goes into block. Also you need to replace oil pan bolts (20). Just use a little rtv at timing cover to block seams and rear main cap seams.
