Just goes to show you that you can't be sure about your bearings. You're fine one mile, the next mile you're not.

These shells were so poorly worn and overheated that they were bowed enough to "clip" onto each journal. Very luck there was no journal damage. Scary, and in the nick of time.
Holy Shit!!!

Cheers,
Basically. It is when the bearing over heated to a point where its shape is changed and grabbing onto the crank. I saw it once (on a different car) when I was at the indy shop.

And the S65 bearing issue is blown out of proportion...

Heres a good one for everyone!

2008 with 162k - approximately 23k on one oil change (yes, I'm probably the dumbest person in this thread for forgetting about changing my oil)

So is that copper colour or just old oil on the shells mate?

Here are mine. Just removed from a 2013 e92 zcp with 32k miles and replaced with BE bearings and ARP bolts by SV Bimmer.

Great shop for those of you in the SF Bay Area. Also did spark plugs and engine mounts.

Contributing my example

MY2010 E90 ZCP, ~57k miles. Oil pan gasket was going and since the pan was coming off, thought I'd get it done. No symptoms or sounds in my case. I wasn't there for the swap, the workshop inspected the crank journals and thought they were fine, no scoring or excessive wear.
