School Me! Rope Style Oil Seal

Lotta folks seem to have zero actual experience with rope seals....
Yes they are more work to install, the actual reason auto makers quit using ropes seals was more about speed of building an engine assemble than a better solution...

Rope seals tend to weep a little oil but it's very rare to have one actually pour out oil... Even with 100K miles they rarely truly leak... Rubber lip seals often weep too though some actually stay dry (Pretty rare) But when a lip seal goes it's common to have it pouring oil...

Yes the modern interpretation of a rope seal isn't as good as the original rope seals were.... Originals had asbestos in the seal, modern ones are graphite embedded...

I watched a few minutes of the video, it seems to cover the basics....

I agree 100% with that assessment. I think speed and ease of assembly was probably the reason for the changeover. But rope seals do leak more often, since they are harder to get right. Once right though, they work well....and yes, you hit the nail on the head about the asbestos being gone. That's big brother trying to take care of us again. That was really good stuff that served a very needed purpose. I don't think there's anything else on the market that could stand up to heat like it could.
