    Yep, it's that subject again! But it's not a 'should I?' or 'shouldn't I?' thread, it'll be a progress and results thread really. Having had the car 10 months now and loving every single second of it I've had a lot of time to read, digest and cogitate over the many thoughts, threads and opinions on the subject.

    I know I've always warmed the car up and I know Bossco did before me but not sure about owner #1. That aside, there's so much evidence to back up the wear rate and clearance issue that I've decided to bite the bullet and take the preventative move of having them done.

    Also looked at a few places to go and have them done and have plumped for my local independent here in Lincoln after quite a few discussions.

    So she's booked in for the 29th October for 3 days (just to be safe) so I'll be posting the progress on here in terms of what the old bearings look like and how the work goes. Have made the decision to go with OEM items (at this stage).

    For info, the car is a 2008 E92 M3 DCT, just under 63k on the clock now, Evolve primary decat with Stage 2 ECU remap, GTS update, 2.5 PCW - full history with regular oil changes with Castrol Edge 10/60.

    I'm in the same boat.

    Car is a Jan 13 with 25k miles, owned from 20k, 1 previous owner + BMW. Despite his re-assurance of always warming the car since he's had it at 6.5k miles. I just can't take his word for it. There's also the other issue I've mentioned on here a while back. When I bought at the time, the excitment got the better of me and I didn't comb the service book properly. Only a few weeks down the road did I notice what appears to be a 17k miles and 4 year gap in oil service so basically 03/13 run in at 851 miles then the next oil change appears at 07/17 @ 18400 miles. In that period it's had other services carried out like brakes, checks etc.

    Called the guy, he claims one was done in 06/16 @ 10400 miles, but the specialist accidently ticked X. Called garage, they said it's unlikely and it was probably not done. When I challanged them for being a specialist and failing to notice the car had its last oil change almost 2 years prior despite only covering 4k miles they turned around and claimed that they go by CBS and if it only covered 4k miles it would not be flagged, which again I challanged since the CBS will pop up despite the milage if it exceeds 2 years. They asked me to pop down to the garage to check their records (can't over phone due to data protection) and they will amend book. I visited them, they took the service book said it was done, without showing me any proof and just re-ticked all the boxes with marker pen to overlap the pen ticks to show that it was done. When I saw, I flamed up. Not even coming to ask me for permission for this so called "amend". You can't notice the correction in the book, however I'm an honest guy and I told them I would feel like a con man if I claim full service history knowing the book was amended to show what was possibly a missed service. He tried to re-assure me it was done and theres nothing dodgy about it and any future buyers are welcome to call and double check.

    So because of that, I decided to just do the bearings. If the car had the same oil in for 4 years and 17k miles, despite his claims of looking after it with proper warm ups etc and the garage insisting it was done and a simple mistake was done on the log, I just don't want to risk it. I would rather do it for peace of mind. Hopefully if I decide to sell it in the future, the buyer will be a bit assured knowing the bearings were done very early.

    Nightmare. At least you're doing the decent thing and you can rest knowing that you've been more than honest. 25k seems early but, as you say, you have no guarantees with that 4 year gap.
    Where are you going to have your done? And what are you using to replace them with?

    I'm based in London, so Evolve were the first choice. Quoted £1400 and included the following:

    • 8x OEM upper rod bearing shells
    • 8x OEM lower rod bearing shells
    • 16x OEM connecting rod bolts
    • OEM Sump Gasket
    • Oil & Filter change
    • 2x Engine Mounts


    I've also found BMS Surrey close to me and saw they do them for half that, so awaiting a quote from them.

    Both use OEM bearings, rods etc. And I agree. OEM are perfectly fine if car is looked after properly and easily last over 100k. There's a chap here who had his done at around 108k or something like that, owned from new and always warmed up etc. Bearings barely had any marks on them.

    EDIT:

    Misread, its 106.000km not miles. Either way just over 62k miles and pretty much spotless.

    keep us updated please.

    I was going to use BMS for all future services on my old M3 as they are not too far. Be interested to know what they charge

    That's really useful to see. I'll give you guys a breakdown of my invoice too but the quoted price for the above, minus engine mounts, is currently £1200 (inclusive of VAT).
    Will probably do a few more bits once she's apart depending on condition etc

    Sorry if I've missed something here, but if the original bearings are prone to failure is replacing them with OEM parts not just delaying the problem rather than curing it?

    With the engine mounts the way we see it you may as well change them regardless as most the ones we see are in a bad way and even if they are not you are saving on the labour.

    no, the oem bearings are fine, its only if the car has been abused or not warmed up properly that they may have issues. same as any high performance engine.

    Not like the e46 issue of the floor failing, no matter how you use the car.

    Interesting thought - do you use OEM parts or fit an uprated pair of mounts?

    OEM. Don't like to change bushings and mounts on road car to uprated as that usually means more noise/harshness. There is nothing wrong with the OEM ones but they age over time and these cars are getting to 10/11 years old now.

    Called this morning, same price as BMR and Evolve, £1400 including mounts, all close enough, and all seem to have the earliest slots available. 2-3 days turnaround.

    From the looks of it pretty much all of the places that do them, are £1400-1500, so it will mostly come down to distance, booking slots and obviously personal preference.

    Just waiting for the parts - was supposed to be done last week but the rod bolts weren't available. Getting ACL Bearings and ARP Bolts fitted. Also taking the opportunity to replace the engine mounts (already sourced) plus changing the plugs as the first stage of trying to source the 2,000 - 2,200rpm judder! Work is happening through.

    plugs will help i had a similar unstable running just above 1500 rpm after picking mine up from bmw dealership .. couldn't be bothered consulting the service department and just decided to bring everything to a standard of my own so carried out an oil / filter change bmc air filter and some new platinum electrode plugs, the plugs in our engines have a very hard life as they spark after combustion to relay information about the combustion cycle back to the ecu so they are also used as sensors. the plugs i removed from mine were around 1.5mm larger gap in comparison to the new plugs, instantly noticed a difference and extremely smooth now
