Sasha39 Posted November 11, 2015 Share Posted November 11, 2015 Can anyone please confirm if the model 65 had a rear main Crankshaft seal fitted, I have pulled down the motor for a rebuild and have noted that the rear main didn't have a seal fitted not even a rope seal.Any help will be much appreciated.Cheers from Downunder.

Narve N Posted November 27, 2015 Share Posted November 27, 2015 It is supposed to be rope seal. I do have a severe leak on one engine in that area and will have to pull the pan soon. Will keep you posted. Link to comment Share on other sites More sharing options...
Sasha39 Posted December 1, 2015 Author Share Posted December 1, 2015 Sorry to hear that you have a leak problem, but am looking forward to the day you take the sump off to see how your's is set up, have tried to find anything about the seal but no luck even the Owners manual doesn't show it or even mentions it.Good luck with yours Link to comment Share on other sites More sharing options...
robert b Posted December 1, 2015 Share Posted December 1, 2015 There is a modern seal replacement for the rope type seal that fits 29 DeSoto to 39 Dodge from Automotive Surplus in Melbourne. The seal is a two peace with three bolt holes in each half that bolts to the block behind the flywheel . You will have to remove the flywheel to replace it . Have just done a 29 DESoto and a 39 Dodge in past few months . Will get the part number for you tomorrow ,ring Automotive Surplus and talk to Reg or Bernie ,should be able to help . If you have any trouble advise me and will get more info . Bob Link to comment Share on other sites More sharing options...
Sasha39 Posted December 2, 2015 Author Share Posted December 2, 2015 Thanks Bob, l'll give them a call and give it a shot, will have to drill and tap the holes as there are no holes there at the momentBut if it works that will be great, the other cause of the leak could be the end cap of the housing for the cam shaft, if the oil return channel is blocked the rise in pressure because of the blockage could force the oil out around the cap if the seal isn't strong enough.Cheers from Sydney and thanks for the advice.

robert b Posted December 2, 2015 Share Posted December 2, 2015 [attachment=On looking at your manual pic it appears that you have only a crank shaft thrower on the rear main and oil drain to sump . There looks to be a baffle system in the drain ,could this be blocked ? Bob Link to comment Share on other sites More sharing options...
Sasha39 Posted December 3, 2015 Author Share Posted December 3, 2015 (edited) hwellens and Bob,Thank you gentlemen I think you'll find the seal in the PDF is for a 1929-1930 Chrysler 66, but I'll give anything a try, and yes Bob as you can see by the drawing no sign of a seal only a thrower that would spin the oil around the walls of the casing and alow the oil to slip down into the drain and yes it is a baffle system and if the drain is blocked that area would fill up with oil and start leaking from behind the flywheel, also if you look just above the main rear bearing you can see the back end of the camshaft and the same thing would happen there if the drain channel is blocked it would fill up with oil and the evevr buliding pressure would force oil out of the camshaft rear bearing plug, aren't old cars fun Edited December 3, 2015 by Sasha39 (see edit history) Link to comment Share on other sites More sharing options...
Narve N Posted May 7, 2016 Share Posted May 7, 2016 (edited) I have finally pulled the pan and identified a likely cause for leaks as the pan cork gaskets front and rear were hard and brittle. To my amazement I had spares from a gasket set by Olson, but also noted that gluing two layers of 3 mm cork together get you close to the prescribed 9&32" thickness. Will try this repair before I pull the rear main seal to investigate if there is a bad rope seal also..With engines I go with the old saying, "If it aint broke, don't fix it".

Sasha39 Posted May 8, 2016 Author Share Posted May 8, 2016 (edited) Thanks for the up date Narve, I will look forward to your report on the rope seal or if it even had one, with the rear main bearing make sure there is no blockage in the oil passage.

I have also dropped the oil pan, and I am replacing the pan gasket because all the RTV that was used by the previous person has not worked in holding back the oil leaks. Just curious to know how you over lapped the two gaskets at the join? I also have used a 6mm cork for the end piece.

maok Posted August 30, 2016 Share Posted August 30, 2016 Thanks mate! You are a top bloke. I cut the gaskets from flat sheet of cork, so wasn't sure of the over lap. Link to comment Share on other sites More sharing options...

pre1939chrysler Posted January 26 Share Posted January 26 No, they didn't. Run your car with 30-wt oil for a while and most of the advice you were given. I have the same problem but just have to work with the felt or leather and it will stop. Just take oil with you on trips. You won't loose too much. Another crank would help and I have a few bur I;ll put up with the leaks ,. Link to comment Share on other sites More sharing options...
stakeside Posted January 29 Share Posted January 29 I do not know the type of seals for this engine but my 29 Dodge DA6 uses the oil sling system. Excess oil goes to a reservoir in the oil pan and drains into the pan. I found that excessive main bearing wear would produce more oil than reservoir could handle resulting in the reservoir overflowing. Link to comment Share on other sites More sharing options...
