Nope, you have to lift the engine. It's because the oil pickup won't allow the pan to slide back and down.

On the V6 I had to remove the right side engine mount and loosen the left one. I raised the engine trans together up about 3" or 4" just enough to clear everything. FYI yes drop the exhaust, as the pan will need to clear it. I jacked up the motor and cut a 2X4 and stuck in where the motor mounts locate and removed my jack. Jack stand at the rear of the trans. Be careful when reinstalling the oil pump, as it has to fit flush with the engine block.
Watch this video and he explains why.

Thanks DocJoe! I'm attached a photo to show you what I'm looking at.



So, in order, you loosened both engine mounts, raised the engine with a floor jack 3-4 inches, and put two pieces of 2x4 inbetween the engine and mounts? Or you only did this to one side?

What do you mean by "floor jack at the rear of the trans"? Is this where you placed it to raise the engine or was this to just raise the vehicle so you could work on it after you raised the engine?

On my van I jacked up the engine/trans and once up I placed a jack stand at the rear of the trans to help support the trans and engine combo. While the 2X4 in the engine mount locations held the front of the engine. Keep the whole thing level is what I was shooting for.
The above picture was taken from my Dodge dealership service manual and this is what it says for both of the V8 engines. Different from the V6/3.9 engine.

Are you replacing the oil pump?? If so put some oil into the pump to prime it, I did not do this step and it cost me time.
