[@hazey888r]

Rod bearing issue is biggest fear tactic plaguing the S65. Think about this, clearance is the issue and oil is too thick, when the bearings wear down isn't that creating increased Clarence? How is it even possible that the wear location would continue to wear thinner causing the bearing to collapse in the center which = spun bearing like described by the mechanic. The wear is actually creating the clearance for the oil to lubricate. Warm the engine allowing oil to thin out which gets into the bearings before redlining and you will be fine. Of course if you don't know the history of the car (some exec who had it on lease and flogged it cold out the driveway) but even then I still believe the wear just created the clearance which allows lubrication. If this was really an issue bmw would have done the recall very early on or at least changed the clearance for the later model years. Keep fear out of your lives, be sensible and enjoy this masterpiece engine.

[@wettm3]

they increased clearance on the newer bearings (as I mentioned in the video) and it still isn't enough. aftermarket bearings further increase the clearance so oil can properly lubricate. www.m3post.com/forums/showthread.php?t=892838

[@leeengland1748]

I heard the harder you drive the car the better as the reason they wear is because the tolerances are so small but driving hard forces the oil around them more wearing them less

[@waltergreif4836]

thanks for the heads up!!

[@abrahamg3354]

2012 ZCP, 71k miles. IDK what to think. I do warm up my engine and drive it granny style the first 10 minutes. I think after 15 minutes I sink the throttle to the floor. I do this daily. Personally, I have high confidence in these engines.

[@wettm3]

yeah I always let the car get up to temp and then get on it. a lot 🙂

[@abelucious]

I watched a guy on you tube who went and changed his rod bearings as a preventative maintenance on a perfectly working N54 engine and about 3000 miles later he spun one of them and destroyed his engine, that made me worry about messing with mine.

Mahle has released a new set of replacement bearings, much better than the BMW original design or any other brand. Same materials and design they use on their F1 engine components. I just did mine 5k miles ago. Car had 85k and the rears were down to the copper. Previous owner was not very kind to it.

It’s so weird the discrepancies we get in the states vs Europe ... Misha Charoudin just did a video on this and the guy Fabsan84 said he never had an issue with bearings before ... but when you see someone do the service the bearings clearly need to be changed

[@aaaaaaxaaaaaa]

Tom at EAS has noticed this as well versus Europe and thinks that part of it might have to do with the shitty gas we have here in US but we still don't really know why it's so different

[@brandonpainter7085]

I have a question: What the best option for replacing TAs? Rebuilt kits? Stock?

[@wettm3]

I'm not sure about rebuilt kits, the biggest thing is to never get used ones. the plastic gears will have already started to wear down, so if a rebuilt kit has new gears it might be ok, but in this case just get new.

So you’ve replaced rod bearings with larger tolerances just to put more pressure on main bearing?

[@javarithms]

I have the same exact car 2013 with 30K and you just convinced me to change my bearings... I was dragging my feet but not anymore after seeing those horrendous bearings. I will go with BE bearings and change them myself since I have a 2-post lift. I disagree they need to be changed every 100K miles especially if you use a bearing that has the right tolerance.

Thank you so much for this great video! BMW M3 is my dream car and I've been wanting one for some time now but the rod bearing always intimidated me. This video answered most of my questions and reassured me quite a bit. I didn't even know there was 2 different types of rod bearing! I was wondering if it's possible to put stronger bearings than the copper or aluminum ones? Thank you again.

[@wettm3]

you will be fine once you swap them out with aftermarket ones 👍

[@damon123jones]

didnt see you check clearance? should it be larger than spec ?

[@reinhart482]

Doesn't this mean the actual crank is damaged too? Does just changing the rod bearings mean the crank has worn unevenly and will prematurely start wearing down the new set of rod bearings too?

[@wettm3]

I don’t believe so, but check on this because I don’t know for certain. my understanding is once the crank is damaged you’d need to do a quite intrusive overhaul of the engine, or buy a new one dependent on mileage/cost of replacement. crank shouldn’t be damaged here, i’m guessing because it’s harder than the bearings, the crank only gets damaged when the bearing spins. again all of this is my thought I have zero certainty about this, maybe someone else can shed some light on this.

Great video! Super important if you are in the market for an E9X M3. I

[@wettm3]

[@niurou]

I think reasons are tight bearing clearance, thick oem oil 10w60 and rev engine to high rpm before the engine is warmed up.

[@wettm3]

engine is always up to temp before revving

[@ndj4267]

Man you need to get an engine tune with catless/hi-flo exhaust. The DME is constantly adjusting timing to different values than it is used to with stock cats...which is why I had some detonation at low rpm with my straight pipe setup. Car now drives silky smooth and torquey with an ESS tune.

[@seanlee2379]

Hi, thanks for helpful video since I am a prospective E92 M3 owner. In S.Korea where I am now, the norm is that you shouldn't really worry about rod bearing issue because it only occurs rarely and if it does, you should get covered by warranty (BMW Korea importer replaced entire engine under warranty when it failed. There were few cases reported that the entire engine failed due to rod issue under 50k KM mileage). I wonder how hard you drove this vehicle, to get this much wear within 30K miles. Were you following all engine warm-up procedure and oil change interval? I know few owners who drives more than 200K KM without rod bearing replacement at all, as a daily driver. It seems that the throttle actuator issue is more prevalent among the E92 M3s.

[@wettm3]

yes I drive this car pretty hard but I always let the car warm up to operating temp. throttle actuators may seem like it occurs more often but that’s because there is no threat of extreme failure to the engine if they fail. you just simply replace them. if rod bearings fail, then the engine is typically seized and cannot be recovered so you have to buy a new engine, hence why people replace them beforehand and do not let them reach failure

[@RSKY65]

How were your motor mounts? Have you felt any difference after RB service?

[@wettm3]

I actually forgot to look at them or film them. oops!

[@Bmwstephen]

this is a reoccurring maintenance item every 30-60K? even after you replace the oem ones with aftermarket?

[@whitenoise5161]

Great video, everything Mike said is correct. Although I did read that the only reason BMW stopped using the lead/copper bearings is because of EU regulations banning the use of lead in car production. Don't know for a fact if that's true, but a softer bearing is always easier on the crank. I had my RBs changed at 40k KMs (25k miles) on my 2010 and while there was a bit of wear on them, it was nothing serious. I went with BE bearings and ARP bolts. Not sure how BE compare to ACL. It's such a mixed bag with these cars. I wonder if the previous owner of your car didn't treat it well/warm it up properly?

[@wettm3]

yes you are correct about the EU regulation, I only found that out after we shot the video. unfortunately still not enough clearance though 😬
