MATT47025 Posted February 12, 2017 Report Share Posted February 12, 2017 Our 1950 Dodge truck has a Plymouth engine. When we bought the truck it still had a jasper tag fastened under one of the head bolts. The main seals are leaking pretty bad and we would like to replace them. So I would like to identify what year of plymouth engine this is. Maybe its not possible I dont know. Can any of you experts out there help.? I have included a photo.

MATT47025 Posted February 12, 2017 Author Report Share Posted February 12, 2017 so where would be the best place to buy main seals and oil pan gasket? Quote Link to comment Share on other sites More sharing options...
Branded Posted February 12, 2017 Report Share Posted February 12, 2017 As far as determining what rear seal its best To just drop the pan. Some told me it was the rope type and some said it was the flanged 2 piece seal type. When I dropped the pan it was obvious I had the 2 piece flange type.

oldmopar Posted February 12, 2017 Report Share Posted February 12, 2017 A vendor like roberts would have them or you should be able to get a local auto parts if you can find someone old enough to understand what you are talking about 1 Quote Link to comment Share on other sites More sharing options...
Branded Posted February 12, 2017 Report Share Posted February 12, 2017 Do some searching for write ups on installing the pan gasket, other wise you'll be tempted to cut the end gaskets. Don't cut any of the gaskets there designed to work and if you try trimming the excess with will definitely have a leak. There are lots of write ups on the subject. I post one if I find it.

MATT47025 Posted February 12, 2017 Author Report Share Posted February 12, 2017 That's good advice thanks, I have bought from roberts before. I will look for the old post on the pan gasket. Quote Link to comment Share on other sites More sharing options...
MATT47025 Posted February 12, 2017 Author Report Share Posted February 12, 2017 (edited) Funny note.... This was an old farm truck. they did what they had to keep them running. The oil sump is opposite of what it should be for a truck so "back in the day" they just modified the pan with a hammer for clearance issues.
