Your front engine mount sounds like it has sagged so much that it has dropped far enough to make clearance impossible. Try lifting your engine about an inch or two and see if you can get the pan out.

What West says for sure, and you will probably have to rotate the crankshaft a bit for the pan to clear the counterweights up front.

Is there a visual inspection indicator for sagging front mounts? I did not observe any noticeable sag, but this is the first Packard I've owned and the mounting setup is unusual to me, so unfamiliar. To replace the front mount, do people chock a block of wood under the engine at a certain point and lift with a floor jack? Or do most use a picker chained to the head from above? @Wesley - thanks, found your video while searching this site in another link. Helpful! @Owen - thanks for the note on the counterbalance - will rotate to be sure it's clearing the pan. That may be the issue.

One way to check for a sagging motor mount in front is to see if you can get a socket on the lower water pump bolts; with a fresh mount they can be accessed but are still quite close to the mount. If you can't get a socket on them, the mount has sagged, pretty basic and easy job to replace the rubber parts. Using a broad and thick piece of lumber under the oil pan as far front as you can get usually does the trick easily.

I removed the cast iron lower flywheel cover when removing the oil pan on my 47 Clipper Custom. I also disconnected the steering linkage where the idler arm fastens to the frame on the right hand side. You may need to rotate the engine so the front crankshaft journals are moved up. This is a relatively simple job.
When replacing the pan affix the gasket to the pan with adhesive and coat the engine side of the gasket with a light coating of grease. Having the gasket adhered to the pan will make it easier to remove next time, and the grease will allow the pan to slide on the engine to line up the bolt holes without hurting the gasket. While the pan is off, check the bolt holes on the flanges for any ones that have been raised due to previous tightening. Check on a flat surface or with a straight edge. A ball peen hammer with the pan on a flat surface will restore the flange. This will insure the pan will seal to the gasket and engine. The bolts do not need to be overly tightened, just up to snug and a little bit more. That should do it. (o{}o)

@JW - Thanks for the notes on how to attach the oil pan gasket to the oil pan and to reinstall.
@Owen - that's a great test to recommend. I went ahead and tried a socket on those two lower bolts and I could not get it on, so the front mount needs replacing. Is the front mount a standalone replacement, or should you replace other mounts when you do that one as well? I actually have not seen the other mounts except the ones hidden at the very back of the transmission - are there only two mounts?

Unless you see that the rear mounts need replacing, you can start by replacing just the front mount.
