When did rebuilders start using the modern rear seal? I am trying to determine the longest period of time since my engine has been rebuilt. It has a modern seal and leaking badly. Does the IO of the seal give any indication of age? When did the trend stop. It looks like it has been a recent change in philosophy looking at several engine rebuilders web sites.

I bought one in 69 when I first restored the car, didn't use it because it required removing the slinger ---glad I didn't use it, recently it was found in a box --then I dropped it and it shattered ----original slinger system working good, rarely a drop once I fixed a crummy babbitt problem.
Prpoer restoration to original specifications eliminates the need for most modifications.
From all the posts about rear main leaks in recently rebuilt engines there are rebuilders still looking for a miracle to solve their rear main leak problems.

I have used several different ones over the years. None leaked but a couple required "tweaking" the tolerances from the instructions.
One BB crank would not clean at the right size when taking the slinger off so I metal sprayed it with SprayBond. It's still running many moons later.
I think a reason many people have problems with various brands of seals is close attention to machine work tolerances such as crank run out and finished sizes.
No seal system will work if the seal surface is not concentric with the seal holder (cap).

Back in the 60ts they used rope seals, like most other engines of the time. Engine builders choice. Chev, ford Y block, Buick. and more.

The one in the picture is a Burtz seal and is sold by all the major suppliers.
