When were the rubber rear main seals first available? I bought a long block last week and got around to pulling it apart today. The engine was very clean, but froze up tight. The block is a EDB with 113 heads and appears to never had any paint on it. I pulled the heads and wow, except for minor rust in two cyl's they look new, never cut and the orginal fomoco valves are sitting high on the seats. I checked the bore and it is std bore. I got all of the pistons out except # 6, letting it soak overnight. I then pulled the rear seal retainer and was supprised to find a rubber seal. When I got the crank out it is std/std. I understand that the EDB block was a one year only 57 292 block. I am thinking that this was perhaps a factory service long block since all the parts appear to have been new when it was assenbled. The only think that is throwing a kink in that theory is the rubber rear main seal, however it did have steel shim head gaskets.

Rear main seal failure is reported in Y-Block literature as quite common, and even experts are supposedly loath to guarantee their work when replacing one. I would be interested in what percentage of factory installed rope seals began leaking way before their expected time?

your engine would have the rope seal when it was new.however someone could have replaced the seal later.

I realize that if it were assembled in 57 (block #) or 58 (head #'s) it would have had a rope seal, but this engine seems to have been assemblied with a bunch of NOS parts and it shows very little wear. I suppose that the rear seal could have been replaced at a later date. I still tend to think that this was a service replacement long block assembly made up of what ever parts were left over. It would be interesting to know how many years after 1964 that ford stocked replacement engines.

Did FORD have industrial units after '64?

Glen. The newest Y-Block I’ve come across had a casting date of August 30, 1967 and had the C2AE casting identifier. That one was a 292 but I've also come across a 312 block that was cast after 1964 also. Blocks were being made at least up until 1967 and I suspect engines were available for awhile after pickup and truck production ceased using them to take care of warranty issues or marine engine installations.

Mystery solved! The fact that this engine was so clean and has very little wear through me for a loop. As it turns out when I got the block cleaned up enough to see, it has 8 sleeves in it. This is the secound one of these that I have run accross, the other one is out at Ted's place. I may make a display motor out of this one of I may drop in a NOS set of std pistons that I have and run it in my pickup.
