Bill Parsons Posted June 22, 2016 Report Share Posted June 22, 2016 (edited) After doing a bit of research on my '54 straight six, I can't seem to figure out what the deal is with oil pans. The lower-hanging part of the pan that contains the float is facing the rear of the truck. Unfortunately, this places it directly over the front axle. Obviously, the oil pan became dented in at some point because of this. Logic tells me that the pan should be oriented the other way around. It seems that every engine diagram I find online has the pan in a different orientation. Here are some examples: http://www.allpar.com/mopar/flat.html Why the differences and is mine correct? -Bill Edited June 22, 2016 by Bill Parsons Quote Link to comment Share on other sites More sharing options...
TodFitch Posted June 22, 2016 Report Share Posted June 22, 2016 Perhaps you have a car oil pan on your truck. . . 1 Quote Link to comment Share on other sites More sharing options...
Jeff Balazs Posted June 22, 2016 Report Share Posted June 22, 2016 Truck oil pans are sump forward. You probably have a car sump......likely swapped in at a later date. Jeff Quote Link to comment Share on other sites More sharing options...
ggdad1951 Posted June 22, 2016 Report Share Posted June 22, 2016 sounds oddly familiar. My truck at some point was in an accident early on and got a car engine as a replacment, which meant the oil sump was in the wrong orientation. Swapped a few parts and I was good to go. on the B series the low hanger should be in the front. Quote Link to comment Share on other sites More sharing options...
NiftyFifty Posted June 22, 2016 Report Share Posted June 22, 2016 My sump is right over the axle on mine...which sucks because it's been dented once from a hard hit..but my engine block/pan was from a combine..and my 218 pan was full of connecting rod holes, so it wasn't going to work.

Bill Parsons Posted June 22, 2016 Author Report Share Posted June 22, 2016 Perhaps you have a car oil pan on your truck. . . According to the engine markings, that is correct. It is from a DeSoto. That being said, what can be done to stop the axle from hitting? Quote Link to comment Share on other sites More sharing options...

Don Coatney Posted June 22, 2016 Report Share Posted June 22, 2016 Desoto engine installed in my Plymouth car. I had to modify the oil pan as pictured. 1 Quote Link to comment Share on other sites More sharing options...

Young Ed Posted June 22, 2016 Report Share Posted June 22, 2016 Truck oil pans are sump forward. You probably have a car sump......likely swapped in at a later date. Jeff Not all trucks. The 39-47s use the rear sump same as a car. Quote Link to comment Share on other sites More sharing options...
NiftyFifty Posted June 22, 2016 Report Share Posted June 22, 2016 Bigger bump stops. Exactly what I did...but I was more concerned with saving my power steering rack..which they also do Quote Link to comment Share on other sites More sharing options...
Jeff Balazs Posted June 23, 2016 Report Share Posted June 23, 2016 Not all trucks. The 39-47s use the rear sump same as a car. Ok Ed you got me......shoulda said B and C series trucks. At any rate the only real fix is to find a truck pan and swap it in. As Mark has said it is an easy conversion and takes care of the problem properly.

Bill Parsons Posted June 24, 2016 Author Report Share Posted June 24, 2016 Swap the oil pick up and pan...easy preasy The block markings indicate that the engine is from a 53 DeSoto Powermaster. That would make my engine a 250ci. Would a truck pan have the same dimensions and would the holes line up? Quote Link to comment Share on other sites More sharing options...
NiftyFifty Posted June 24, 2016 Report Share Posted June 24, 2016 Any 25" block pan should work, but you also need the oil pick up as well from the donor engine I believe Quote Link to comment Share on other sites More sharing options...
55 Fargo Posted June 24, 2016 Report Share Posted June 24, 2016 (edited) The US built trucks with the shorter 218/230 engines and the front sump pans fitting on the longer engine? You will of course need as mentioned, a 25 inch truck oil pan, easy in Canada, as all were 25 inch engines, the pick up assembly, and swap, not difficult. or do as others have suggested, bigger bump stops, I would lean toward a truck oil pan. You can get 1 from Canada no problem, or off the big trucks in the USA.. Check with Tim Kingsbury or George Asche in Fertigs Pa, PM Tim on this website, if you want, he can hook you up possibly.
