[Assimilator1]

Right, I've looked through all the photos on this thread, and there are 308 submissions which are still available and of good enough quality.
I also looked through photos from the past 6mths on the Face Book group BMW E9X M3 V8 UK Owners Club, adding another 61 submissions.
Additionally I looked through ACM's rod bearing specials thread adding another 156 RB jobs.
Yes I've looked through all of those 525 submissions! (and more which had bad quality photos and weren't included!).

Of the 308 from this thread, just 2 are in good condition which barely show wear (as they should be), and just 7 are moderately worn!
If you include the 7 moderately worn shells, 9 out of 525 is a mere 1.7% of them!

120 are knackered (e.g for the lead/copper bearings, showing copper), that's the lead/copper type bearing.
I didn't see any tin/alu/copper bearings that were breaking up or clearing showing copper, but I did see quite a few that have worn through the upper babbitt layers (I put these in the excessively worn list).

[update] Following a little experiment by me later on, where I rubbed down some of the babbitt layer of an LCI bearing, copper can clearly be seen (lists and text have now been updated to reflect that. I also added a 'contaminated damaged' list to separate those damaged by external factors).

From the FB group, 24 are knackered.
From Matt's ACM thread 93 are knackered!

And from my 'Excessively worn' list their are 180 submissions here, 36 from the FB group and 58 from Matt's thread.
I've listed the 2 good cases and 7 moderately worn ones below, I won't post the whole list as it's massive! Lol, but if anyone wants me too I will, I've attached my notepad file which contains the list to this post. Each list has a link to the owners original post, so you can judge for yourself if you like!

Note that these lists don't include engines where the bearings have spun or the engine has blown, they're mostly in addition to those! (and in another thread).

Regarding my classification of the bearings placed in the excessively worn section, these are contentious & subjective, some people will argue that some of them should go up to the knackered group, & others will argue that some of the less worn ones should go into the moderately worn section. We are in part (at least) limited by the fact that we can't feel what they are like, sometimes they might look ok but would feel rough, which means they are knackered! If multiple people say that I've clearly missed something in a certain photo then I will re-categorise it.
(Possibly I should just merge the moderately worn section with the excessively worn, with that just covering a wide variety of wear. But I've left it for now).

With the tin/alu/copper bearings, although they do have a thin coppery layer https://www.m3post.com/forums/showpo...postcount=1222 https://www.m3post.com/forums/showpo...postcount=1937, it seems LCI bearings don't normally wear through the babbit, although in most photos the oil micro grooves (see 3rd photo here https://www.m3post.com/forums/showthread.php?t=1486113 ) are clearly worn smooth, & so would compromise the bearings oil retention to some degree, as well as being worn unevenly, hence placing most into the 'excessively worn' group. But the main point is that they are not showing normal 'slight' wear for a mostly non contact surface.

The ones that are clear cut are the lead/copper bearings which are showing copper, this clearly shows that the soft babbitt layer has worn through. This layer allows particles to embed into the shell & thus prevent crank damage, as well protecting the crank when starting and stopping the engine, if it's worn ultra thin (e.g copper showing at the edges) or it's just plain gone then this protective layer is gone & the crank is imminently vulnerable to debris damage or pick up, & thus scoring &/or seizure under those conditions. If you don't believe that, then read the following literature by the bearing manufacturers:-

Showing copper = shagged bearings, no ifs or buts, it's clear cut.

So out of all 525 cases from my list, 516 are either knackered or excessively worn, and just 2 showing barely any wear!
For the suspicious people out their who might claim that Matt only posts the bad ones (because it's his business thread), his cases account for 156 of them, but even if you dismissed those you're still looking at 2 good ones out of 360 cases! And even if you include the 7 moderately worn ones, 9 out 360 is just 2.5%! (Not to mention they are valid cases anyway).
And yes other business's have posted jobs in this thread, but they only account for a very small number of submissions, and in addition to that, 1 of them (deansbimmer), posted 1 of the good removed bearings!

Knackered bearings
(For either type of bearings, that's showing copper, to varying degrees).

My photo of an LCI shell where I've rubbed down the babbitt layer exposing the copper, and also showing for that shell (at least), that the babbitt layer had not worn through.

And no I'm not affiliated with deansbimmer , he just knows his stuff and makes good posts . Also he's in the US at Mporium, and I live in the UK and work in a small Suzuki dealer as a master tech. (I am going to buy some parts from him soon, but that's it).

Phew, that was a long time in the making! And I'm not done yet, as I want to find more photos of rod bearings in good condition (from any engine) from high (ish at least) mileage engines, to give more examples of how they wear. Early days on that! (just what's listed above atm)......
