Wondering if I can use an oil pan from a 1940 110 on my 1941 110..both have same engine I believe…the 1940 one is in much better shape, however, they are different on the inside of pan..Pretty big change in one year…also the 1940 one is painted correct green but the 1941 is painted black…the dimensions appear the same …any help appreciated..I will add photos..the 1941 is on the left..

Packard made running changes with some later engines getting a pan with more oil capacity but with the different shapes of those two pans, you might want to carefully check to see if the pan you want to use will clear your front crossmember. In 41 the Clipper was introduced and while I believe the 40 and 41 conventional body frames might be similar enough to take the same pan it is possible the different shaped pan might have been for a Clipper engine which is on a different frame.

Ah ok..I wasn’t thinking about it fitting on the outside..I was more concerned if crank would hit inside of pan…I will dry fit it to check crossmember..tks

The crank and everything inside are the same but the first thing I thought of and as Howard pointed out is the suspension. I have a 1965 Imperial LeBaron which I was told when I bought it in 1972 that the original owned had replaced the engine. One day I noticed oil running out from under it an into the gutter which turned out to be the cross-linkages on bumps were touching the very lightly pan and over the years wore through! They had used a Chrysler pan rather than an imperial pan and, as the two are different makes that share virtually nothing in common, that was an issue. In your case, Packard was redesigned for 1941 so there may have been suspension changes or even a slight shift to the engine's location so best to be sure!

Ok thanks Don..will check when I get..home..starting think you guys may be correct as the drain hole on the 40 is on the side of pan and on my 41 the plug hole is under center..so maybe that’s the reason..tks

Going by memory as I'm not out at my shop at the moment but I seem to recall that my 1940 110 pan is different than both of those. I definitely don't remember the drain being in the side!

Yup doesn’t fit..with frame..definitely the original,pan from a 1940 110..any advise on how to flatten pan bolts holes before reinstalling pan and new gasket…it appears there is a raised ridge around pan and hole surrounds but unsure how much force I should use to flatten around the holes

On mine I used a body hammer and dolly to true up the pan lip. (I had to do the pan too as it had a huge dent crushed into the bottom!) I kept referencing progress with a straightedge. I found the metal moved fairly easily. Something about the Rockwell hardness of the metal then allows nice rework without spring back that you get on modern sheet metal. The centre rib stayed fairly true during rework too and at final assembly I coated both sides of the pan gasket with sealant to ensure a good seal. My gasket came in 4 pieces so each joint got a lick of sealant too just to be sure.
I am sure you will be able to get a good result with some light tapping and patience. Go slow as you do not want to over work and stretch the lip, then it will remain wavy on you. Likely the stress deformation has been at each bolt hole from torqueing and crushing the gasket so first work those back.
Upon assembly another tip too is to allow the gasket to seat. Do this by torqueing in stages and let it rest for some time between rounds, stops the gasket from spreading out as much at each fastener.
