I've emailed Damian for a quote.

Good on U mate :beer: I hope you've used the correct ARP bolt link ? as in this one: http://www.turnermotorsport.com/p-22...-m10-size.aspx ... and not the first one I posted in error :smt053

Yep

pasted the second link :thumbs:

Sorry "select" :smt053 wrong ARP link ... these are the ones I meant :http://www.turnermotorsport.com/p-22...-m10-size.aspx :thumbs: Highly regarded by race engine builders.
... and I'm aware of the nature of any stretch bolt it's single use only :smt023
Good luck with your CSL tomorrow and I'll be interested to see the pix of your old engine bits

No Harm done, matt. :beer:
Didn't knew that those are availiable in M10.. but i am thinking if the current BMW ones held up 100.000km the new ones are going to aswell..

Onto the bearings.. took some pics but apparently the camera is a bit beat up .. sorry for the rubbish pics :bigcry:
Trying to get some better pics done..

Car has had 110.000km or 68.000 miles when they were changed.
Mechanic said they are in a rather good condition, he has seen way worse.
But Cylinder 6 is the worst as it always seems to be the case with the S54.

re: main bearing and oil pump change

a few peeps recommend this @ 60k miles

Is this preventative maintenance or another example of extreme over servicing?

Just a thought as my car is @ Barts at the mo.

It feels like over egging to me but I each to their own I guess. I'd expect an engine to go a fair bit longer than 60K before it needs new shells etc.

People would do well to remember the basic failure rate bath tub curve. You can actually increase your potential of suffering a failure by replacing things early. Replacing head gaskets 'just in case' seems an unnecessary risk to me, I can't think of another engine where you'd do that. Even the K-Series community has the patience to wait for them to pop first. Wear rates on oil pumps are usually low, they are robustly designed, submerged in oil, and pump oil all day. Hardly a high wear environment.

There is a degree of logic behind the "If it ain't broke, don't fix it" approach.

I agree with the above. My decision to go ahead with the preventative maintenance stems from an accumulation of events-

1. a friends csl suffered total bottom end fail @ 70K miles- verdict- thrown main which destroyed the crank
2. Gareth @ Bart's has seen several csl's in recent months with the above failure.

I'm hoping a little invested now will sustain the car well into 100K + miles especially as my annual track day quota is likely to rise.

- Vanos filter, and pressure check
- Diff. oil
- Gearbox oil
- Rear exhaust hangers

Mine had a comprehensive engine rebuild not long before I got it, I will try to find out more details of what was done at some point, but from what I heard it sounded very much like an oil pump failure, all done under warranty. It also had a gearbox change. Neither of which were preventative. Preventative maintenance would have been a lot more expensive for the owner at the time though. Having a vehicle with a good warranty on it and liking to carry out preventative maintenance on things like main bearings don't go all that well together IMO.

I have done an oil change which wasn't really required though, does that count?

Had an interesting chat with Damian today re warranties and preventative maintenance.

He was more than helpful and it's great to find a company that are that way and don't try to scare you into having work done needlessly. It's exactly the same as 1320 are with looking after my GP.

Reading the posts re having the bottom end done to defer bearing failure, I started to have a bit of a think about mine which is currently sat on 74,000 miles. I tend to agree with Ben and will more than likely have them changed along with the oil pump when it goes in to have the brakes fitted.

Until the old bearings are out we are never going to know if it's a wise move or not, however, not sure I'm going to be happy to wait and see if it is going to go bang along with my bank account which would also go bang at the same time :hahaha:

In the case of the GP, more than a few have been seen to be having timing chain hassle. The guides tend to wear / break leading to the chain jumping a cog and leading to a few bent valves. Mine's booked into 1320 in Oct for new guides and chain so I suppose, if I'm doing it on the GP it would make sense to do it on Cesil.

Damian/Natalie & Gareth have a great set up as you'll discover when you get the BBK fitted. Damian is never to busy to deal with the smallest detail with the csl which is very reassuring. I wouldn't take my car anywhere else despite the 6 hour round trip. :thumbs:

The car went down there for a once over 2 days after collecting it and was impressed with the attention to detail.

Peter (Trawler) took me there when he bought his car to 1320 for me to have a look at one in the flesh.

I'm like you in the respect nowhere else will be doing anything on the car.

It's good knowing I have Bartletts for cesil and 1320 for the GP.

Seeing as the bottom end has been discussed, what are the thoughts on having the head gasket changed as a preventative measure?

Brian I've hopefully headed this off at the pass.

Having a compression test done at the same time as the main bearing/oil pump replacement.

Results should give an indication as to the state of the top end.

Cheers Ben, likely to be doing the same.

Brian the compression test is about 7.5% of the cost of the bottom end /oil pump maintenance so it's relatively money well spent.

Well worth having done then, thanks.

Mine is being sorted when it's in for the brakes, not cheap but if it gives peace of mind it's worth it.
