The upper bearing shell takes all the the loading, when the cylinder fires the force pushes the piston/conrod down onto the crankshaft thus loading the top bearing shell.
Dave.
Yea but also there's one bearing in particular that is worse than all the other upper bearings. Is this just how they might wear or indicicative of an issue?

I am gradually reaching the conclusion that I should get this done to my ///M which is also on 107k miles. That would see it through to the end of my days! However, I'd be so p!$$ed off if the shells all came out unmarked!

OP - where did you take yours and can you share price please?

BMS Surrey buddy, i had additional work done but i believe shells and an oil change would be around £800 mark maybe a bit more bit not too much.

I had a new PAS hose fitted and new engine mounts too which is why mine was a little more.

They also found i had a leaking constant pressure valve so they supplied and fitted that at the same time.

I was fearing it would be three times that! Somehow £800 seem like a bargain now! Lol

My car has done 107K now, had an oil analysis which came back with a caution due to high lead content.
Should I retest after an oil change ( which is over due ) or just book-in for rod bearing change?
The car is a keeper!
Any thoughts appreciated :D

Changing the oil won't repair the damage the bearings must have suffered to give the high lead content reading.

Book in for a rod bearing change if you're planning to keep the car IMHO

Thanks for your advice, that is what I will do.
Just thought maybe the high lead could be because the oil was overdue a change.

Also an oil analysis report doesnt give the whole picture as it only represens a moment, and its the sum of all wear in the engine for that moment.
If you're at above 100k miles, you're about 50k miles overdue.

One factor that's difficult to guage with the bearing wear is usage prior to the current owner. Most aren't one owner cars and as such could have been tracked or just run 2 miles to tesco's and back, there's no real way to tell.

Exactly, which is why I got it done immediately on mine, they weren't actually too bad for the mileage, but it was worth it for peace of mind.

I fully get the peace of mind element, but were the old bearings worn? I was talking to BMW technician who said that he had never seen knackered shells, even on cars with over 150k on the clock.

Mine weren't too bad.
Maybe he hasn't, Phil at CPC certainly has.
I've spoken to several people both here and on M3 Cutters who's shells have gone, causing major damage. Have you seen the state of Hopz' shells on page one of this thread? I'm sure many are a ticking time bomb, why risk it?
