Default Crankshaft scoring


Thanks for the help, got it all apart and found this. Seal was broken and the little coil in the seal scored 1/4 circumference of the crankshaft. I have a speedi sleeve for the pulley, but this scoring is on the inner circumference of the crank and the pulley itself rather than the pulley and the seal. Is there a sleeve for the crank itself? Thoughts?

Broken seal. You can imagine the oil leaking from the front engine. Happened at home only driving in the driveway. Couldn't miss the oil puddles.

No worries. The seal seals against the pulley hub on the id and the front cover on the od. The clearance between the pulley id and the crank is too small for oil to leak out there (there is no pressure in that area if you have a working PCV system.

Default HB Pulley wobble? Can't remember if it was there before

After reading a few other threads sounds like a slight HB wobble might not be a problem?
new seal and speedi sleeve installed. No leaks yet!

However I noticed the HB Pulley was wobbling and I don't remember noticing it before. It's noticeable compared to the other pulleys. I tried to post a 5 second video but the file type isn't supported.

Thinking I may pull the bolt, see if I can get it to seat any more and reinstall the bolt. I'm nervous to pull the HB pulley as I'd rather not interfere with a new seal just installed.
Thoughts?

Easy enough to pull and inspect. I'd do that.

Also, you can just post a video to YouTube and post the link here.

Default HB wobble video

https://youtube.com/shorts/4jjk4SF6T...hareHere's the short clip from below
and the clip from above in reference to the other pulleys. HB is the bottom most pulley in view.

Default HB Wobble

Pulled the bolt made sure the HB pulley was tight and reinstalled, still wobbles. I'm starting to suspect that tapping the speedi sleeve onto the HB caused the inner and outer parts to move just slightly. My rubber spacer is dry and has cracking but no gaps or chunks missing.

When at 2000rmp the wobble is less visible but could be spinning to fast to tell..

Should I be worried?
Thanks all for the help!

I like the idea of the speedy sleeve, but myself I have found that its worth paying the extra to get Genuine LR Oil Seals as the OEM ones are just not as good a will leak to sum extent

Those are unrelated. You can/should use a Speedi sleeve and an OEM seal.

The wobble in the youtube clip is inconsequential. Some of these just wobble and for the cost of a new HB, I'm firmly in the let it wobble camp if it doesn't leak lol.
