455 Rear Main Seal

Does Any Body Make A Ruber Lip Rear Main Seal That Replaces The Rope Seal?

I Know They Are Made For The Earlier Blocks Pre 64.

Any Help Would Be Appreciated.

By coincidence, the sealing area of the two crankshafts share dimensions. Some parts suppliers actually carry a rubber seal listed for olds, its the same, just ask at one of your local auto parts store.

As for changing the seal with the engine in the car , its a real challenge. The transmission would need removal. One of the motor mounts would need to be loosend to remove the oil pan. Probably best to replace the seal with the engine out of the car. But thats my opinion on how to do it.

Have used the Ford seal at least 4 times. To do it right, the crank should be polished good. The last one I put in, while having the crank turned, I also had the Kneals removed. I have also installed as is and had no problem.

I also used the 460 seal with no problems or leaks to date.
