It's all risk isn't it, who knows till you take them out... I'm going to do mine at 60k and at the same time I'll do the top end too (and probably some cams )

Most BMW Tech's wont be working on these cars anymore as most are serviced by Indys now, the choice is yours what you want to do regarding it.
The fact is unless you know 100% the history of the car and previous owners you wont know how it has been treated.
I was glad I decided to change mine after I saw the state of the ones I removed from the car, it now gives me confidence to use the car to its full ability instead of constantly worrying if it will soon spin a bearing at the top end of the rev range.
My car had a pretty decent service schedule too and since my ownership the oil has been dropped every 6000-7000 miles, I would have thought there is many cars which are as bad or worse than the wear seen on my bearings.
For the price I wouldn't think twice about changing them, if your car decides to spin a bearing it will be a lot more than £800-£1000 and could even total an engine!

Thanks for the advice.
I have decided that, assuming the Zed doesn't need a lot spending on it to get it through an MOT, I will get the shells done this year. As has been said £800 is not a lot for the peace of mind. I plan to keep the car "forever" and want to make sure that the car is not the one that packs up first!
Additionally I got the car at a great price 3 years ago, have only spent money on servicing and tyres. If it was a "normal" car I would be looking to move it on at a loss, so in theory the "Zed bank" is in credit to the tune of a large sum!
Thanks again chaps!

This is quite true: a friend of mine is a BMW technician and he also agrees that it's quite rare for them to see cars of Z4M vintage or beyond. He drives an E46 M3 though and changed his rod bearings at 130k kms. Not knowing how it has been treated by some of the owners before me, I intend to do mine at around 120k kms.

In this thread, there are several mentions of 'not sure how it might have been treated before you got it' and 'it might have been tracked' implying that high rpm and track use correlate with premature wear of the bearing shells.
I had mine changed at 50k miles and they were perfect. At that point, mine had covered 25k unknown miles in the hands of the previous owner, then 25k miles in my hands. The latter miles were spent exclusively between 7500 and 8000 rpm, including a great many miles of track use.
The anecdotal evidence from my experience does not support an association between the car being driven hard and excessive bearing shell wear (although I accept that n=1).

Will have to wait and see what 150,000 road/track/ring miles have done to mine...when I eventually get around to getting them looked at
Mine doesn't move unless it's going to do enough miles to get everything up to temp (engine, coolant, gearbox & diff) - so I always make sure my short (less than 10 mile) trips include the 'long way home'.

TBH I would suggest the wear generally prone when the car is not up to temp. So short journeys, going past 3000 when not warm etc

This. People ragging their cars before up to temp is what wears the shells is what I've been told.

Not running an ///M I hadn't realised that the S54 uses relatively heavy 10/60 and as mentioned in the review someone posted it takes a while to properly warm the oil in the cast iron block, I'm guessing he has a point.
viewtopic.php?f=2&t=97645&p=1432728&hilit
As a matter of interest, why such thick oil? I was wondering if it was to maintain the very high oil pressures needed at the high revs the engine can work at?

It takes a long time to circulate properly and the tolerances are so small that until the oil is warm and circulates wear is inevitable. It is a wearable part although BMW doesnt actively promote this as by the time most cars get to the 100k mile mark they are 6-7-8-9-10 years old and they have moved onto the next latest and greatest.

With mine been over 107k miles now, first drive of 2017 was on wednesday, shortest route to the workshop.
Had a quick chat today after they checked cyl1, enough to see it was worn (not badly but still) so they ordered a set of new shells now.
It'll feel good having done this!
Will put up pics next week.
