Me buying a 125,000 mile E92M with rod bearings and throttle actuators already done: 🤠 Me not realizing that I’ll have to do my fuel injectors, valve covers, and main bearings: 😭
Only the front main bearings have an issue. The timing chain pulls up on the number 1 main bearing. Run a thousandths of extra clearance and you won't have an issue. The rod bearing will definitely be destroyed if the number one main bearing spins.
at your mileage it would be easier to just get a used lower mile engine and do the mains on that. Main bearings are an engine out job. Not really worth it and the failure rate is much much lower than rod bearings
@@brarautorepairs it's not an easy job like rod bearings. The engine essentially needs to be taken out and rebuilt. That is why not alot of people do it. They wait for it to go bad and get a used lower mile engine and maybe do the mains on that. Tons of these cars are in the 200-300k mile range on original mains
This is an unbelievably informative and compelling video. I've virtually every video and read basically every thread there is on this car, so some new information here is really refreshing. This guy clearly knows hit stuff. Amazing job. Only thing I might ask for is some recommended service intervals on some of these items. My 09 has 68,000 miles on it and I'm trying to determine what to do, what to wait on, and what to do while you're in there. The list seemingly never ends with this car (and according to the forums you should basically just replace every single item in the car as soon as possible), and I know age is a factor, so some more specific recommendations on mileage/age would be great!
We created service kits based on BMW recommendations for the F8X generation M2/ M3/ M4. They've been fairly successful, so creating something similar for E9X M3 would make sense!
@@AlexNelsonFCPEuro Would also love a similar breakdown of the DCT transmissions for these cars as I know it was developed in tandem specifically for the S65 V8 and is a technical marvel in a lot of ways in its own right!
Probably replace throttle actuators because the bmw ones are garbage or you will go into limp mode have the dsc light on. I replaced spark plugs also it was pretty easy but im sure with the actuators and new injectors car will run smoothly for a good time I have not changed rod bearings im at 144k miles owned since 110k
nice breakdown of the motor. you should do them all !! this was great. new respect for the s65 too. i was admiring those timing chains in light of the audi 4.2 v8 ... what a mess.
Thank You. I feel so much more knowledgeable now. I have an E93 M3 and it’s dialed in now! I also really appreciate all the E9X content. Keep em coming 👍🏾😊 “Smiles per gallon” 😂
Only thing to add is replacing the main bearings isn't a simple preventative maintenance like doing the rod bearings. It's far more complex; you might as well rebuild the motor at that point. Main bearing failure rates are relatively low, so many actually recommend not addressing it proactively, as it can introduce more issues when the work is not done to a very high level of precision.
so glad to finally be an owner of one of these. just tracked it last saturday and couldn’t be happier with this platform, AND it carries the looks. only issue rn is hot starts it likes to stall, presumably fuel breather valve
Do you mean cold start? It does that like most cars to heat up the catalytic converters, it was really useful on cold mornings to clear frost of the windscreen 😁 I used to wait a couple of minutes before driving off
@@mfujii1318 Ah, didn't know that was a thing. Mines was low mileage though and traded her in when she got to 5 as I was fed up with all the questions why I was spending so much on a basic service.
ARP rod bolts are much easier to torque up than the OEM bolts, ARP is 1stage, whereas OEM are something like 4-6 stages for each bolt! Main bearing failure is much rarer than rod bearings, personally I'm not going to bother with those, unless mains failure becomes more common or I see signs of trouble.
Excellent video. I know I will reference this often as my 2011 E92 ZCP gains mileage. Currently just broken in at 43k miles. It’s the plastic and rubber bits I suspect will go first and should be inspected.
Excellent video and great information! Thank you! I love my 2011 ZCP E90 M3. I just wish I would have ordered it without a sunroof and with the 6-speed. Can I ask where did you get the “M Power” carbon fiber valve cover pieces from? Nothing sounds like this car at 8600 rpm’s (stage 2).
RE the main bearings, how much of an issue is this, really? Many cars are going on for 150k or 200k miles+ without them failing, so it can't be that big of a deal? It is an engine-out job, and costs a fortune....I would get this done if it is definitely an issue that WILL happen, but if the odds of it are very low, is it worth it? My car is on 97k, I had the rod bearings done at 85k and they appeared in good condition. It is a 2011 E90 saloon. I only do 5-7k miles/year, so even if I leave it to 125k miles that's still another 4+ years away yet....?
Great content! More for the S65 please! I’m at 182k and going strong. Need valve cover gasket but nothing else hopefully. Rods and actuators done at 130k as pm.
Sure do! Any specific Audi Engine you have in mind? We may have already done it on our other DIY Channel th-cam.com/play/PLe_--lhvXud9wWhv3yIzDoCUFwqNayHJl.html
With proper warm up and oil changes every 5k miles or less, I argue that the rod bearings can last longer than people think. I changed mine at 80k and they had very little wear: th-cam.com/video/OVA85yF6gKg/w-d-xo.htmlsi=A0gvaS2gB4itUvF6
An excellent and very useful video! (only seen to ~23mins so far, I look forwards to watching the rest). Some minor corrections though, it is rated at 420 hp and 414 bhp, not 414 hp. The S65 is slightly lighter than the S54(!). The belt routing was changed in the latter part of April, not mid May 2008. I didn't know about the throttle rod needle bearings! I had assumed they were bushed and so maintenance free. Can't say I agree that the plenum is easy to take off (and I speak as a mechanic of ~30 yrs), the rear jubilee clips, especially the left side (on a RHD car) is a right pain to get to (even using 1/4" extensions and a UJ). An e92 M3 owner.
I'm glad you enjoyed the video :) The S65 does however produce 295 lb-ft of torque (I'm assuming is what you meant), not 414. Per the technical overview of the 4th generation M3, available from BMW TIS, the S65 produces 414hp @ 8300rpm, and 400Nm of torque (295lb-ft) at 3900rpm.
Nice, but I still love my 2013 Lemans blue 335IS, DCT and only the joys of an N54, NOT an S Motor. Now with brembos, an LSD, Konis and delrin arms and rods for rear suspension.. And still only 79K miles. Al I have to do is normal gaskets .. not the whole rod bearings, and throttle bodies world of the S65..
This is why the majority of the industry shifted towards forced induction. It’s still pretty cool to have over 100hp/liter N.A., high revving, small displacement V8.
Way too many issues... To buy an E9x M3 and making it bulletproof with all preventative maintenance, you could have bought a Porsche that is far more reliable.
I dont think so. You buy one (here in Germany they are around 30k) and if you do the stuff yourself you can make it pretty "bulletproof" for 5k Of course its a M Engine so dont expect reliability like a M54 I dont know any car that has a High Rev V8 with that sound for 35k You cant really get a 997 Porsche for 35k and even if you do, those engines have Lots of weak Points too @@Clintpoon
WoooooW! The BMW E9X S65 V8 #SnyderCut Video. 192k Miles and still going. DCT Failed at 176k miles $$$$$$ What is that BMW Power carbon fiber valve cover coil pack cover? Ran out of M3 Mods, except for the NRW Valve Covers.
25 k ?? It's a bullet proof motor. Had 2 e92s. Just warm them properly and you won't need a set of bearings until 150 k miles and then they don't cost much to change
Brilliant, thanks so much. Re the rod and main bearings - are there different ”classes” depending on the actual tolerance? Do I need to know the tolerance before ordering the kit?
We spoke about rod bearings, and regardless of how crankshaft load affects bearing wear across the engine, you're still going to service all of them whenever the caps come off.
@@romuztek +1, main bearings are by far the worst problem these engines have and need more awareness. They're failing left and right and it's almost always irreparable.
I am experiencing weird noises at startup. Abit like metal clanking/rubbing? This noise goes away 3/5 secs after start up. The engine goes beautifully thereafter. What should I do?
As a bmw engineer I can confirm my heavily modified turbo k20 has lasted 19 years and still going stronger than ever we aren’t the same I don’t drive bmws
To me, any modern car that needs a rod and main bearing service before 100k miles is problematic. BMW made their name making aircraft engines, how in the world did the engineers not know about the bearing issue before producing this V8 and the V10?
They don’t need mains to be clear, but BMW has had issues before this engine with rod bearing (S54 specifically) and it is not acceptable IMO I have to agree. Now if you really baby the engine, drive off right after startup, keep below 3500 revs until oil is up to temp, these bearing will last way longer and not need changing so early. Mine is tuned to not rev past 3500, then staged to 4500, then once fully warm the full rpm limit. Blackstone lab tests after oil changes on older copper bearing come back perfect each time. All that being said, you’re right it shouldn’t be this hard and fragile. The BMW’s middle name is MOTOR!
The S65 does not feature donut knock sensors, which is why you can purchase aftermarket adapters to run them. Therefore, yes it does use them for knock control, as it would have no other way to detect knock.
Unpopular opinion, I never liked the s65. It revs TO high Has no torque down low Makes pretty bad power (even for back then) Never driven one so cannot talk about drive ability etc, and it does house in 1 of the best looking BMW coupes ever made.
The P65 used in the M3 GT2 was indeed flat-plane, however this was the only variant (aside from Judd uses) of the S65 which received the flat plane crank. The Z3 GT3, and all S65s produced, are cross-plane. This is the main reason for the sound difference between the GT2 and the Z4 GT3.
