    Are you kidding me? If these let go instantly don't you think there would have been a recall?

    Didn't the S54 have to change bearings? Did they all fail? No. Did some? Yes. Did some with Boost? Yes. Did some without boost? Yes.

    You are making dangerous suggestions based on nothing when the body of evidence does not remotely correlate. You need to be held accountable for these types of posts.

    Exactly.

It's very hard to blow these cars up from abuse.
    The oil starvation issue is key from my perspective especially now that you highlighted how it can have an effect on the rod bearings.

    Aren't there oil starvation issues with the S65 to begin with? I was speaking with someone about this today.

When it does thIs, it beats the bearing slightly out of round, kind of like bending a wheel. Now the oil film that the bearing rides on gets scrapedoff by the bearing on every rotation, and starts to take metal off the bearing....over time it wears away, develops play(which is the knocking noise you hear), the oil pressure drops down because of the huge gap now, and the bearing overheats and welds itself to the crank...and bye bye block.

    I'm not saying all the M3s did this, but in this case it prolly was a combination of the 3.
    I prefer not to speculate but what we do know is BMW changed the rod bearings and there have been a string of failures attributed to rod bearings in cars ranging from SC'd, to stroked, to stock that were running the early rod bearings used. That leads me to the conclusion it is a faulty part.

    There is more to this but I have to be careful...

    Bingo it will be very easy to see on the rod bearing itself - along with the tops of the piston/piston rings. A compression test result would help too. All which I'm sure will be completed.

    From what Gintani told me today, they intend to be as open with this as possible as there is nothing to hide. I quickly jumped in to say I would document every piece of the motor as it was being disassembled with high resolution pics for everyone. They did not seem to be opposed to the idea and Drew is not hiding anything either.

    So what I can tell everyone is you will see inside the motor.

    There you have it M33 said it so it must be true....Tell me how you know this since you haven't seen the motor? Is that some kind of special skill you were given at birth? I wouldn't make bold statements like this without knowing for sure and you don't so you shouldn't state it as fact bud.

    Drew, very unfortunate to hear. 2007 was a year for our C6Z's that is known to have weak rod bearings as well, there have been many accounts of failures in stock cars...ya never know. The fact that your car has had 10k of POWERFUL boosted miles is great, you really drove that car how it should and unfortunately something happened. The fact that Gintani is covering the cost is incredible. When I blew my boosted motor in my C5 Z06 I was left in the dust, had to go to a new shop, and shell out thousands and thousands of dollars to be back on the road again. I give both yourself and the guys at Gintani a lot of respect for how the situation is being handled. I'm sure you will be back on the road in knowtime with tricks up your sleeve giving me runs for my money Click here to enlarge

    My sister's 08 M3 is a DCT. I believe she ordered it the last month of 08 production.

    My M3 is an '08 build as well and DCT, how is that possible M33?

    Jamie,

    The same statement was brought up on M3forum, a statement which I have never heard before from anyone but you and this other poster. This guy is named "CP3" which I was sure was Pencilgeek, or is this you! I'm kidding of course, but I do find it odd that you both would post this, are you chatting about this with CP3?

    It is a possibility, but like others pointed out, normally other things go first.

    Yes, that is Robert.

    I'm curious, how is this Gintani's website again? Gintani wasn't even one of the first sponsors here. Really it is OE Tuning's involvement and support that makes Gintani's sponsorship possible as Gintani isn't all that active on forums.

    Secondly, what exactly is wrong with the title? Rod bearing failure and as stated there is complete transparency here with the desire to show everything in the motor on disassembly. What else could people possibly want? The old man tries too hard, where are the pics of his motors internals?

    Drew,

    Sorry to hear...PITA but you got off lucky in more ways than one.

    A few years ago a BMWCCA member by the name of John Holder had a rod bearing failure on his S54 at a rather high speed down a straight away, (Race track) and did an enourmous amount of damage to the car. (I think the bill totalled nearly $30k...and he didn't hit anything...although he flew over a water drainage ditch) Imagine having a rod failure at high speed, having the oil from the block coat the rear tires.....and well...you know the story from there.

    A very visual example of this can be seen on youtube from a certain car doing a top speed run in the "Silver State Classic".

    I look forward to seeing a more in depth analysis of the failure, certainly for learning, and not to point any figures. I think the way this thing has been handled so far has been pretty classy by all parties.

    Drew, thanks for sharing this with the community. Thumbs up to you for being honest and transparent with all this and Gintani for going above and beyond. Hope you get back up and running soon.

    Other than the ticking noise that you mentioned, were there any other signs? I'm sure you'll gain more insight once they open up the motor, but is there anything preventative that we could do?

    I have to admit, this makes me nervous, since I just installed an SC on my 08. I was not planning on installing gauges but now you have me thinking about installing some to keep things in check.

    You have me really worried now.

    I was planning on going after some high speed records with my car, maybe not any longer when scenarios like what you described are possible.

    I didn't think it was you, I was just messing around, this drama we've experienced between us needs some humor now and then. From what I've seen, for the most part, when logic comes into play, and the info is obvious, unlike others you tend to come around and have no ego in that regard. I see no problem with you and PG sharing information and posting it, and you make some good points as well, no worries.

    Knocking/detonation does cause Rod bearing failure as well! When it detonates a with a high load, it pounds the rod bearing to the crank which will leave no oil film in the rod bearing surface.

    Only the early S54 rod bearing recall are due to too tight clearances for a high revving engine + heat that ended up seizing the rod bearings to the crank wear when everything was driven hard. Thus BMW fixed the issue by using racing rod bearing clearances & used thicker TWS Motorsport oil.

    Definitely, but that does not seem to be the issue here. This seems to be more inline with the bearing issue similar to what the S54 experienced or else we would not see repeat failures for these bearings across tuned and stock motors for a certain year.
