    Out of curiosity Nicom, what's the reason for replacing the engine?

    Cheers

    Sunday morning as always driving to the valeter, warmed up as usual pulling onto a dual carriageway, in goes 4th 60mph oil pressure low beeped, smoke everywhere, pulled on a lay-by oil everywhere. No warnings, no rattles no knocks, been my daily driver past 6 months not an issue already had 2 oil changes.
    Took it to a local garage this morning massive whole in the sump can see the side of the piston engine completely destroyed.

    Oh no! And there are people who still don’t believe there is a problem with the bearings in this engine.

    How many miles did the engine have on it?

    62,842 miles. I’m gutted, does put me off a bit tbh, having had a c63 prior for 3 years covered 115k trouble free driving other than regular oil changes. fancied a manual so decided on the e92 which I absolutely loved till yesterday. will think twice after it’s fixed if it’s a keeper or not.

    Really sorry to hear that. I’ve got a manual too and I love it but there’s no doubt that despite being a generally tough engine there’s definitely a weakness in the bearings.

    Obviously not everybody will be affected but that’s no consolation to somebody like you whose engine blows up for no apparent reason. I have proactively swapped out my rod bearings for larger clearance ones. I don’t know if that is any guarantee but I feel less paranoid about it blowing up.

    I wish you all the best in sorting your car out. They are great cars when they are working!

    Thanks buddy. I’m going to be hit me a 8-9k bill shortly which don’t really fancied spending that money on a engine tbh. I was enjoying it how it was before.
    You mentioned swamped ur bearing for larger clearance ones. Did you go aftermarket or does BMW offer OEM ones

    I went for BE larger clearance bearings with ARP bolts. There’s loads of opinions on which bearings to go for but having carried out my own research these are the ones I decided to go for.

    BMW only offer bearings with the same clearance as were supplied with your engine originally.

    But using OEM BMW bearings would need to stick with a 10w-60. Warming the car up properly prior to a heavy acceleration I’m pretty confident these bearings will last a very long time. Have you changed your oil grade with the BE bearings or still using 10w-60.

    I’m using 10w-60 with the new bearings. Done 15,000 supercharged miles on them so far.

    So from your expierance using the BE bearings with 10w-60 still does the job. Is there diffrent sizes when you go oversize

    Yes, but I’m just relating my experience and opinion - not giving advice.

    I think BE bearings just do one size of bearing which gives fractionally more clearance than the BMW bearings.

    Ever so sorry to hear, terrible experience. Assuming it will be a used replacement engine, while off a fairly quick job to get new rod shells in. From there you have a "new life" although painful bill initially.

    Wish you good luck!

    Yes believe BE has one (undersize, 0.0025mm extra gap together) shell. ACL also have a 0.0025 increased pair. Believe VAC also provide a bit more clearance, very popular choice with ARP bolts btw.

    OEM from mid 2010 has a tad more clearance (0.001 or so) than previous engines.

    What year is your car Nicom?

    Its a 2008. I was looking at the ACL bearings but cant decide whether to go fir aftermarket liKe BE, ACL with ARP BOLTS or OEM BMW.

    Best quote iv found for a used replacement engine is £6,000 and roughly another £1500-£2000 labour cost with service items and gaskets, but apparently no warranty is valid if the engine is opened which i am because il be replacing the bearings

    Sorry to hear that Nico, i think i would be wanting to look into the failed engine for what actually failed, there are a couple of possibilities. Rod bearings one of them, but other things can fail.

    I think in that case i would want to know the miles on the new engine, and its age.

    Then make a decision about rod bearing closer to when the warranty expires, OR the other option is ask "what discount for no warranty?" - and then do all the bottom end bearings and other things. Good luck.:thumbsup:

    Yea i know what you mean. Most people i spoke to funny enough 4 engines had miles ranging from 20k - 35k no more. Seems these breakers only keep low mileage engines
