Was engine able to be saved? Was a simple bearing job necessary? Was the engine replaced? If so, how much was the total cost and how long was the car out?
I would say 95% of the time, the outcome is the same. In our experience, 95% of the time (let's call that 100% of the time), the rod knock causes crankshaft damage -- even if it's not visible to the naked eye. You need to make sure the crank journal is still round, even if it looks perfect to the naked eye. A micrometer will get you in the ball park, but not perfect for measuring the roundness of the journal. Only way to be 100% sure is with the crank out of the engine and measure with a dial indicator. If the journal is a few 1/10000's out of round, I think you'll be replacing the bearings again -- and next time it will probably be much more costly. I've seen it happen. On a different note. One crankshaft looked perfect, but magnaflux showed it was cracked. The crank had to be junked.

I would say $15k - $18k as is.

I agree. In our experience once there is audible knock it won't be a simple bearing change anymore. Crank has to come out, at the very minimum. Usually the engine will need to be rebuilt to remove the bearing debris from throughout the engine. Any shortcuts will often end up with problems later and having to do it again.

Hi. I think I saw your car today as I was getting my RBs done. Definitely some nice cosmetic mods you have on the car (nice wheels, lip, rear spoiler, etc). Not sure I'm a fan of the debadged M3 though.

But though I heard from Malek that it needs a new engine?....so sorry to hear that this might not be driveable for a year?

Haha yeah I broke the badge that came on when I got my car dipped (it's a liquid wrap but high gloss) earlier this year and just haven't purchased one yet. I talked to Malek around noon today and he said it's an interesting case since the knock is intermittent and I'm running e85 so it's a bit harder to diagnose than what he's usually used to. He said he's most likely going to drop the subframe and pan on Thursday if he can't get a good opinion on everything. Will keep everyone updated

We have a rebuilt S65 for sale in case you're interested. Sorry to hear about this happening to your car, it's really a shame so many S65s reach their demise in this way.

Yes it's there and thanks! I dropped it off when it was super dirty the color looks a lot better washed that's forsure. Btw if anyone has any questions about the liquid wrap or wants to inquire about getting their car done feel free to PM me and I can explain it! It's definitely a very impressive product.

Thanks! That's actually a different m3, similar purple but it's in a matte finish. He's had his bumpers unwrapped for over 6 months haha not sure why exactly

If it is the RB I don't feel one bit a sympathy for the OP. He spent a bunch of money on mods and cosmetics and rolled the dice on rod bearings.

I bought my car with 85K. I took it to MRF the next day and paid the $2500 to get the bearings replaced.

First, I would fix the motor. Selling an M3 with a blown motor makes them close to worthless. You're looking at getting about $10k at the high end? It's not just the cost of the motor but there are other implied things like...not well maintained. That assumption tanks the value of any BMW and more so for an M car.

Rod knock...new crank and rods. Probably worth rebuilding since S65s are still $7k to $9k. Unlike an S54, cheaper to just throw in a used motor.

In case you're shopping around, be aware that the crank is surface is heat treated. Once you spin the bearing and wear the surface, you have to re-heat treat the crank or it won't last very long. I haven't priced S65 cranks but I was quoted $1000 to grind and heat treat the crank. At that point, might as well get a new crank.

BMW sells undersize bearings but it's to account for wear, not "I didn't spin my bearing that bad". Went through that already.

I am pretty sure OP, nor anyone else is looking for your sympathies or approval.
But thanks anyway.

Just met a couple with an M3 the other day. They never heard of rod bearings. Reason being they don't spend their days on forums reading about M3's, not even a minute. They saw a car they liked and they bought it, nothing more and nothing less.

Normal . That's like 90% of the M3 owners...and they always just dump the car after they heard that strange loud knocking noise coming from under the hood

Update from Malek: he pulled the filter and saw metal shavings but he said it was very minimal and something thats pretty rare. He's sending the filter out to get analyzed and he will have an update Tuesday. The analysis will let us know if the shavings are consistent with bearing failure or bearing wear. He said it's looking pretty good though and there's definitely a chance all I need is new bearings. I'll let everyone know what the update is on Tuesday.

I'm pretty sure your situation depends from how your crank looks like .
