E9x M3 Owners - Mileage/Bearings

[jettaz]

Hello everybody

Trust everyone had a leka weekend. :cartel:

I just wanted to know, are there any S65 owners that has more than 100k on the clock that has not done bearings on there car?? and when is it ideal to do this?

We have E93 M3 at home and she's just on 98k and the bearings havent been done as yet.

Trying to just get a feel as to when the guys would normally do this and costs and places to go. (Cape town)


Thanks. :ty:

Might be a good opportunity for all the owners to meet and discuss costs and maybe call it the Bearing run :tiptoe:

LOL!! Dont be like that man. :rollsmile:

Is it that much of a thing? 100k isnt even that much!

Hey buddy if you looked well after your car there should be no reason to change bearings. I dont know what the hype is about this knock knock kak. If you see most of the people that has replaced bearings at high or low mileage their bearings are not bad at all. Most of the pictures I have seen is just normal wear. I dont know where people get the idea bearings is not suppose to show wear. If bearings did not wear then we would be having disastrous engine failures.

People sending in vids of bearing knocks and if you listen to it then it is just the sound of a normal high performance V8 engine making a noise. You can clearly define when it is a bearing knock. These engines are a work of art and if looked after properly you should enjoy it for a long time. Proper cold start and good maintenance then there should be no problems. I do all that to mine and I ride it to its limits and enjoy every single minute of it. There are owners that have over 200k on the clock that have not changed bearings.

also OP just search the forum this topic has been discussed a few times as its well documented that the //M's run bearings with there even being a recall on e46's & some e92 owners getting theres done under motorplan. IT IS WELL DOCUMENTED. The only thing that may not be covered is where to get them done in CPT :coolShake:

Well, as stated above the bearing issue is fact. Im personally aware of 4 S65s that had bearing knock. Out of all the people I know that has S65 M3's, I'd hardly call this issue an exception.

My attitude? Get it done by a reputable shop. It's a small price to pay if you consider the alternative.

And yes, some break at 60k km and others have done 220k km without issue. You cannot know for sure without pulling the bearing shells off.

Thanks dude....Thats my concern... I dont know of many personally. But everyone mentions it and thats scary....hence me asking this questions.

I always say if shes well taken care of, then she should be good....But all this talk did make me worry about this... (Knock Knock)

I have a E46 M and the bearings were done over as part of the recall BMW did... i havent had a issue since.

Do you guys think that driving the car hard could cause the pre mature bearing failure? even whilst being well maintained.

I read most the topics but i still had a few questions so ja....Hence my post. :hammerhead:

 

[individj]

i can tell by response that you probably won't get it done. thats your choice...might be fine..or might run a bearing tomorrow.

:roflol::roflol:
"IT IS WELL DOCUMENTED" Please show where BMW replaced e92 bearings under motorplan in South Africa.

if your car had a bearing knock and it was still under motorplan.:=):
you do you & choose to ignore the facts. it has happened to so many m3 m5 m6. 6 v8 v10. have a good evening

What has the m5 and m6 got to do with the e92/e93. It is not the same engine. How can you make this ' this might sound paranoid Jettaz but i would be scared to drive the car. " statement to the OP . Are you a foretune teller. Do you even know the condition of his car

 

[individj]

it has been proven that even well maintained cars are running bearings.
what they have in common is that they are //M engines & all have the same issue.
And it honestly brings me no joy saying this.
As Ratslaaf said..some have 200k on the clock with original bearings & some go before 100k & even with good maintenance.

Terrynew, the m5 and m6 have the v10 which is identical to the v8 of the m3 less 2 cylinders and a few changes to the oiling system. It is a well documented fact that both these motors (v8 & v10) run bearings. Being a owner of a e92 m3, and having my engine go at 98k km due to bad bearings, I can safely say and advice anyone who has, or purchases one of these machines, to at least have their bottom end checked out.

As to why the issue exists boils down to various factors, that a quick google search can shed some light on.
I chose to get rid of the whole problem, and got custom designed and manufactured forged internals.

 

[Ratslaaf]

Uhmmm, the S85 and S65 is more alike than not. They all use the exact same bearings and crank design.

 

[Peter@AEW]

The common thread on the s series of engines is the very narrow big end bearings which were installed.

Less friction more revs.
A good maintenance regime is advised however that alone will not insure against failure at some point in the future.

To propose that copper showing through the bearing is normal is not correct.
If that were the case than the main bearings would equally show wear which is not the case.

Is it advisable to at least check them ...yes. At the very least one would have peace of mind.

Every single engine I have opened has required bearings and I am by no means the only one to have observed excessive bearing wear on the big ends.

My M3 is on 135 000 with no issues .

I have a friend with the same model that ran bearings on 34000 . The engine was replaced by BMW . The cost was R160k. It took 2 weeks to replace .

Therefore my oppinion is that mileage makes no difference .

 

[terrynew]

Guys I'm not disputing the fact that some e90/ e92/93 M3 has had engine failure due to bearings, but no one can conclusively state what the cause was.

There has been no official statement from BMW saying that there is a problem with the e90/e92/93 M3 bearings. If you see the percentage of vehicles with issues is very little compared to vehicles that do not have issues.

Vehicles have problems all the time because they are not perfect but please do not create a problem for a vehicle if there is not one. It is good to give advice but do try to scare people of facts which you are not certain of. There are many owners that are enjoying their vehicles without these issues
