austinsailor Posted April 16, 2011 Report Posted April 16, 2011 As I started to clean up parts for my 251 truck motor I'm overhauling for my 42 Plymouth 2 door it occurred to me that the truck pan is front sump, the car rear. No problem, I pulled the pan and pickup off a 48 Desoto motor I have and it'll put things in the right place. Except the dipstick. The truck dipstick is in the pan, the Desoto is in the block. With this combination, I have none. At this point I plan to cut the dipstick part out of the truck pan and graft it into the Desoto pan. Anyone have any thoughts on this? I suppose I need to make sure it won't clash with steering box or other things. Other than that, any ideas? Oh, I also realized the truck has the motor mount bolts on the bottom and they go directly into the frame. But I have another inner part from behind the timing chain that has the mounts on top and will get it back to the Plymouth setup. Quote
Jerry Roberts Posted April 16, 2011 Report Posted April 16, 2011 Some blocks that had the dip stick in the pan had a small plug in the block where the dip stick could have been . Perhaps you could be lucky . Quote

austinsailor Posted April 16, 2011 Author Report Posted April 16, 2011 There is a plug in that general area, but the dipstick hits the pan flange if you go through it, and will be in the way of the full flow filter housing. Quote
Merle Coggins Posted April 17, 2011 Report Posted April 17, 2011 If you're using the pan from a DeSoto motor, why not use the dip stick from that one too? They should match up just fine and shouldn't interfere with the oil filter. Merle Quote
austinsailor Posted April 17, 2011 Author Report Posted April 17, 2011 the desoto has no provisions for the full flow filter and the hole isn't in the same place, just near it. obviously it misses the pan on the desoto, but with the desoto dipstick, Desoto dipstick tub and Desoto pan on the truck block it hits the mounting flange of the pan. I could cut a notch in the flange of the pan and weld it up but I wouldn't be able to use the full flow filter. Quote
Don Coatney Posted April 17, 2011 Report Posted April 17, 2011 (edited) This is how my Desoto engine looks with the full flow filter and dipstick in place. Edited April 17, 2011 by Don Coatney Quote
austinsailor Posted April 17, 2011 Author Report Posted April 17, 2011 After looking at Don's pictures and studying both blocks I think it will clear the filter. the desoto mount where the tube screws in is a little inboard and a bit higher than the truck block. I also noticed the pan gasket is notched where it is on the truck block, although neither pan is. it looks like I can cut a notch in the pan, weld a piece around it, and re-mark the dipstick and I'll be good to go.

Drdialtone Posted April 19, 2011 Report Posted April 19, 2011 Don, the "full flow" filter you have on your DeSoto... does this use a spin on filter? What's the benefit of this? Thanks! Quote
Don Coatney Posted April 19, 2011 Report Posted April 19, 2011 Don, the "full flow" filter you have on your DeSoto... does this use a spin on filter? What's the benefit of this? Thanks! A cartridge filter element is used. Benefit is all of the oil goes through the filter prior to going to the engine. That is why it is called a full flow. This is a factory option on some long block Desoto and Crashler engines. Not available on Plymouth and Dodge engines made in the USA. Quote
