hi all thanks for letting me join you. I am in need of some info regarding what has been used to replace the 2 piece neoprene rear main seal in a 1957 235 cid. I have been told and it was confirmed by a tech rep with Federal-Mogul that Felpro has discontinued the 2 piece seal that they had for the 55-62 235\261 engines and have not replaced it with anything but a rope seal. I tried to use the rope and could not get it to fit in the "V" grove that the old neoprene seal came out of, no how-no way. The rope is just to large in diameter to get down in the grove. when I did get in (I thought) and I put the bearing cap on, the crank would not turn, too much pressure from the seal.
the old Felpro part number is BS13363 for the seal kit, I can find no cross reference to another manufacturer and the tech guy said that it was not superseded or replaced with another part, just not made anymore. just wondering what someone out there may know or has done in this case. any input would be really helpful. thanks in advance.
