This is an interesting read from another M3 forum

Those look good as they dont have the characteristic oval wear spots.
That's how it starts (before the copper shines through etc).

Those 2 shells where it looks like little pieces of the layer started breaking out is a bit odd. Maybe that's how it starts prior to the oval spots.
But overall very little wear even for 60k miles, so you can be assured your engine has been treated very well over the years.

I was really happy with this outcome to be fair. Everything else (suspension bushes, dampers, engine mounts, etc) was checked as part of the insp2 and found to have similarly low levels of fatigue/wear. Naturally it will always have whatever it needs spent on it

I'm a new owner, at 90k miles and no history shows that it has been done on mine, I'm trying to find a garage to do it in Devon, but proving harder than I imagined. I feel content to pay £1300 ish to prevent a £5-6k bill and the hassels of a goosed block. I'll report how I get on with the repair.

I had an instant quote from Munich Legends of £1300 all in, which was perfect, just that I live in Devon.

I'm not British but do know that Bristol is closer:

Prices and all
They say the plastigauge both the old and new bearings, which is a lot of work.

You can ask them to install a new oil pump piston, a known wear item.
You can get DLC coated ones:

(I don't know what else you need for this like bolts, o-rings or gaskets, but I'm sure the supplier knows)

Mines in at Redish currently - can't recommend them highly enough based on their work so far! They will do you a video showing the old bearings and crank condition etc - really great service

While you certainly won't go wrong with Redish, you could also try Forza GB in Caldicot, they sorted my car for £1100 with BMW bearings/bolts last year. They also provide a 15% discount to this forum for labour that I was not aware of at the time

Seems quite reasonable prices given the required precision/ detail?

Yes it was, I have found Forza to be very competitive on labour rates over the years. Just had a look at the invoice and the bearings cost £297, bolts £36, sump gasket £35. While it is a precision job, it is very common work for all BMW specialists. The service schedule for these cars should be oil, INS 1, oil, INS 2, rod bearings

Saying all that, I do send my car to Redish for certain jobs as the service they provide is top tier. It is going there next week for VANOS refurbishment actually.

+1 for Redish Motorsport.

[DSGRNMCM]

Thanks All,

Just updated the "list", I'll wait till my garage here finish's the INS 1 and suspension and brake work, before I get it back.

If you’re prepared to drive to Amersham, Phil at CPC Performance changed mine.

Mine was undriveable due to suspected rod bearing failure at the time - so it was taken down on a car transporter van. If you're wanting to look at doing the same I recommend using shiply.com - very useful for sorting out car transportation, various operators will outbid each other for your job, so you get a decent price

Thank Ed,

Mine is fine (Touch wood) I just want to get it done as a preventative measure / peace of mind and t assist in the car holding value as it approaches 100k (on 90k now)
