mopar_earl Posted August 26, 2015 Report Share Posted August 26, 2015 (edited) Hello, I searched the forum but had no luck. I have a 1952 Dodge D42 Coronet Club Coupe with the correct 230 engine. The gasket set the machine shop supplied has a two piece bolt on rear main seal. The engine had a two piece rubber seal when we took it apart. The engine is 5 hours away at a friends and I will be going out this weekend to assemble it. He isn't sure we can use the bolt on seal. Which seal is correct? Where can I get the two piece rubber seal if that's the one I need. The two piece bolt on is a felpro. I looked online and all I can find listed is the felpro bs6300. Can't find the two piece rubber insert seals. One goes in the bottom cap and the other slides up in the block. Thanks, Earl Edited August 26, 2015 by mopar_earl Quote Link to comment Share on other sites More sharing options...
mopar_earl Posted August 26, 2015 Author Report Share Posted August 26, 2015 I just did a search of 1951, 52, and 53 and all call for the felpro bs6300. Is it safe to assume this correct and what we took out was incorrect or Dodge changed the design and what was in it was the old design? All I can find is bs6300 or rope seals. Can't find anything on the two piece rubber seal. Earl Quote Link to comment Share on other sites More sharing options...
50fordtruck Posted August 26, 2015 Report Share Posted August 26, 2015 I have a 1953 Plymouth block in my 47,most places told me I had to use the rope seal however 53 had a two piece in the block seal. I found one at Hagens in Washington State. They are very expensive,around $60 there. I would check the engine # and make sure that your block is the correct one for your car, there may be no bolt holes for the bolt on style.Hope this helps.

It's the correct engine for the car and should be the original engine to the car. Earl Quote Link to comment Share on other sites More sharing options...
mopar_earl Posted August 26, 2015 Author Report Share Posted August 26, 2015 I won't know if I have the bolt holes to use the bolt on seal until I get out there. Rather have other options than to get out there and find I can't use the bolt on seal and have no backup plan. Earl Quote Link to comment Share on other sites More sharing options...
Don Coatney Posted August 26, 2015 Report Share Posted August 26, 2015 This might or might not help. This information is from a Motors Manual for my 1953 Desoto engine. It appears there was a change in 1953. 1 Quote Link to comment Share on other sites More sharing options...
mopar_earl Posted August 26, 2015 Author Report Share Posted August 26, 2015 Thanks Don. I did notice Dodge and Plymouth had different cut off years on the insert rubber seals and bolt on seals. I can't find any listing on the rubber insert seals. Felpro only lists that bolt on seal kit for all years. So I don't know if they discontinued the rubber inserts and now only use the bolt on style and my engine will have the bolt holes? Would be a major hold up on the engine if the bolt on seal won't work on my engine. Being 5 hours away with tolls and all, I would like a plan b seal kit such as the rubber inserts. My engine and car are 52 year. Don't know if early or late. Earl Quote Link to comment Share on other sites More sharing options...
mopar_earl Posted August 26, 2015 Author Report Share Posted August 26, 2015 The felpro bolt on is listed at least up to 1955. My car had the style your manual says 53 year models use. But the bolt on is listed for 50 to 55 and maybe later Earl Quote Link to comment Share on other sites More sharing options...
mopar_earl Posted August 27, 2015 Author Report Share Posted August 27, 2015 I found a source for the two piece rubber insert seals. Unfortunately I can't have it by the weekend. So hopefully this bolt on seal kit will fit. If not it won't be much of a productive trip. It's called a "in the block" seal and the kit I have is "outside" the block seal.

Dodgeb4ya Posted August 27, 2015 Report Share Posted August 27, 2015 Here is a picture of a 1952 Dodge 230 Wayfarer engine. It has a 2 piece rubber rear seal in it. The block and cap will accept the bolt on type too as the 6 holes are there also. 1 Quote Link to comment Share on other sites More sharing options...

Appreciate it! I will feel better on my 5 hour drive to work on my engine. Thanks, Earl Quote Link to comment Share on other sites More sharing options...
Merle Coggins Posted August 27, 2015 Report Share Posted August 27, 2015 As I recall, when I rebuilt the engine in my truck the gasket kit came with the rope seal and the two piece bolt on seal for the back. I remember that bolt on set looking more like a dust seal than an oil seal. I may be wrong on that, just my memory from 9 years ago. Quote Link to comment Share on other sites More sharing options...
mopar_earl Posted August 29, 2015 Author Report Share Posted August 29, 2015 We ended up ordering a best gasket brand 3675 two piece rubber inside block seal. We didn't like the bolt on style. Looks like a guaranteed leaker. Also we'd have to dig up bolts and hope the fluid coupling studs would clear them. Earl Quote Link to comment Share on other sites More sharing options...
harveyspoint Posted August 30, 2015 Report Share Posted August 30, 2015 Mopar Earl......My 1953 Motor's Auto Repair Manual, on page 754, shows this about 1953 rear oil seals.....It says,'A new neoprene rear main bearing oil seal is incorporated on all engines. The new seal is a lip type with a steel channel insert.' Quote Link to comment Share on other sites More sharing options...
