As per the title, I'm about to address the leaking rear main in the '51 216 in the 3600 in my tag line again. Bought the truck with 43k original miles back in 2014, it's now at 59k. In the past 10 years I've replaced the rear main rope seal with the Best Gasket graphite impregnated seal two times, each time the fix lasted several thousand miles then the leak reappeared. At the moment, it's to the point that clutch chatter is making starting off in second gear almost violent. 1st is even worse (T5 transmission).
I'm going to try the stainless windshield wiper reinforcement strip method of slowing or stopping the rear main leak. Many to include Jon (third post on this
pageand Hotrod Lincoln (Jerry) have suggested this old school trick.
While getting ready to tackle this little job I've gathered up a couple stainless wiper strips, one is a bit over a 1/4" wide and the other is about 1/8" wide. Now for the question, anyone know how wide the grove is in the block under the rope seal that will accept the stainless strip. Hopefully I'll have one on hand when I tear things down.
Thanks,
RonR
