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.

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.

Any pics yet buddy?
Collect today! Oh great joy.
Well, horrible pic content, shells in no particular order (got all in a bag):
Needless to say, this was at the last minute!
Cyl 1 shell even had small holes in it. (See pic) Haven't seen that one before..
Surprised/relieved they could not find a single scratch on the crank surfaces.
Mine's a 2006, 178926km (111179miles) car. Bought it at 154000km's, so I don't know the details of that distance other than it's been well serviced at BMW according to the service stamps/receipts.
Paid 16177kr for the job (about 1463£)
Runs a bit more quiet now I think, or I imagine.

The pitting looks like classic cavitation caused by inconsistent crank pressure due to wear or flex at max revs, this causes collapsing high-pressure air bubbles between surfaces or around trapped particles (same process that destroys boat propellers). It can be made worse by incorrect oil grades, over-revving or poor oil hygiene, this is different to the wear caused by abuse when cold which also looks like is there as well. A well timed change

Wow - your link to "MY CARS" is fantastic!
How did your Fiat 125S end up as RIP though?!
My second car was an Olive Green Fiat 125, but not being a 125S it had tan vinyl trim with no cloth! I bought it from my parents after my dad had a stroke that left him in a wheelchair for the rest of his life (12 years).
But what a great car that was back in the early 80s - twin-cam engine, 4 wheel disc brakes, etc. (But it did rust - a lot).
Thank you! What a terrible thing a stroke can be.
But yes the 125 was among the Great Fiats in my view, my dad had several, all rusting away swiftly..
My own green 1972 Special was a mint original, the last one in its kind here in Sweden, but I didn't get to drive a single meter until the garage caught fire and killed off both the 125 & the Fiat Coupe.
Horrible. That's when I panicked in life & bought my Z4M!

I bet you are glad you changed them now, they could have let go at any time!Argenta said:Mine's a 2006, 178926km (111179miles) car. Bought it at 154000km's, so I don't know the details of that distance other than it's been well serviced at BMW according to the service stamps/receipts.

Was that a BMW dealership price?
Or is there a good specialist you use?
