Rear Main Seal Type???

[55 Fargo]

On my 218 25 inch Canadian engine, what type of rear main seal might I have.

The engine was from a 1950 or1951 Plymouth or Canadian Dodge.

It is the type of block with the internal bypass water pump and narrow belt pulleys.

Does anyone have an idea when they changed the rear main seal type on these engines?

I will be doing my pan gasket soon, might as well do the rear main, if I have the type that can be changed without removing the clutch housing and flywheel. thanx Fred

you can get the lowers...it's the upper half that presents the problem with the bolts. the rope seals are $8.50 napa..(got mine today) the neoprene seals are more...

i bet you have the rope seals.

Thanx Claybill, not sure what seal I may have yet, can the rope type seal be done without flywheel removal....

the lower for sure is basic. theupper..well you ahve to fish thru the new rope..frustrating they say!

i am looking at doing mine for the leak as well. i took an old motor apart to see the work involved. oil pan removal, rear bearing cap removal (2 bolts)

then the seal is lookin' at you! if it is the neoprene type you have to unbolt the seal/ retainer, as it is one piece,...still lookin at you! however, the upper bolts are problematic, as all have stated. that's what i can see.

Hi, I do not see oil leaking from the back of the pan down, or on the front of the clutch housing pan either, i mean there is a slight amount.

The leak is on the bottom of the oil pan near the drain bolt.

Now years ago, one welded ona piece of 1/4 plate steel, to the whole bottom of the pan, wonder if that is leaking, and I wonder why it was done in the first place.

I do have a nice donor pan here to replace this one with..........Fred
