I had to have a little laugh at that; Sreten's excitement at the E60 making the correct amount of power and being 'original' and having done 150k miles... Is it really original with replacement vanos pump, new injectors etc etc (I forget all the things he replaced). With all that stuff replaced, what could possibly rob it of power with every conceivable wear item replaced? Is it really fair, on any street car engine, to regard rod bearings as wear items? Grandfather's axe, or trigger's broom, spring to mind. I'm glad he's stoked, but I certainly do remember watching him replace all sorts of parts of that engine.
Don't get me wrong, I'm not complaining at all. But that felt really odd to me! |

It's not highly strung. It makes 100hp/L. I'm not saying it's trash, don't get me wrong. But I don't agree that it should be praised simply for not grenading completely in its 150k miles.
Anyhow, this isn't going anywhere positive. Let's move on |

Blend doors? Temp sensor? Compromised heater core?

However, ya rod bearings should not be a maintenance item. Especially when the vehicle cost $120,000 (2023 USD)

That's huge for a NA engine and it makes all that power at 8k rpms. That's what high strung means. Think Honda S2000. Today's turbocharged gassers are more like high performance diesels. Big power at low rpms.

I don't think it's the heater core, I think it's got something to do with the electronics. Sensor, blend door, etc. I think you're on the right track, but I guess we'll find out

I vote for blend door. They gave in me a ton of shit in my old lexus. Either not letting things work or making loud screechy noises.

If you remember, that same Vanos pump had a broken bearing race and a big chunk of steel was circulating in the engine and it still remained unharmed which is even more impressive. Internally, besides the Vanos pump and rod bearings, it's all original. Cams, Vanos units, Vanos solenoids, timing chain and guides, head gaskets, valvetrain, pistons... all untouched. It is a highly strung engine with very tight tolerances. 4-door, N/A 5.0 L with 507PS, 8250 rpm redline and a factory 6-speed manual that covered over 150k miles. Can you think of another one? By today standards, 507PS is easily achieved, but keep in mind this thing came out in 2005 with development starting way before that. Think Lambo V10 or LFA won't need rod bearings at 140k miles? Probably impossible to find one with such mileage and not comparable cars, but E60 M5 is a cheap way to experience a V10 if you were to compare them. Worn pistons, rings, cylinders, cams, bad timing, bad Vanos.. can rob an engine of power at that mileage. Yes, I agree, rod bearing maintenance on a street car is not normal, but then again this is not a typical street engine. I just took apart the S65 engine (derived from the S85) and you'd be amazed how much racing inspired engineering went into it. If you were ever to own S85 or S65 engine, you have to come with the term that the rod bearings are simply a maintenance item cause of the tight clearances. That said, I replaced them at 142k miles and they didn't look terrible and probably had more in them, but not something you want to gamble with. I put BE bearings with more clearance, which in theory should solve the rod bearing problem, but I'm yet to confirm that firsthand. I'm planning to remove them at some point and check them for wear. Anyway, my point is, the E60 M5 is not as bad as internet made it out to be and if someone is on the fence whether they should own one or not, they absolutely should. I'm not saying the maintenance will be easy or cheap cause it won't, but treat it right and it'll treat you right. The S85 is, IMO, a masterpiece of an engine that BMW can't make ever again and should be enjoyed thoroughly. Dunno if you ever drove one, but try it for a bit and you'll be ready to put up with everything, haha. I should add, I'm heavily biased and deeply in love with project Raleigh. 😁 Yes and yes. I do like it better and I don't like admitting it. 😅 I adore E39 M5, but E60 M5 is arguably a better car with a lot of right updates. To name a couple: steering rack, x100 better seats, x100 better brakes, EDC suspension. Simply put, a proper successor to E39 and I love them both. |

Appreciate your response, Sreten. Please don't misunderstand; I'm really not complaining about anything. If I had the money and time I'd do the equivalent on my car, but I don't. The s85 sure is an awesome engine. But regarding the stress levels, it surely compares with a Honda k20a which had very similar specific power and rev ranges. The k20a has (as far as I'm aware) no issues with longevity unless it's severely mistreated...which is a lot more likely in a civic than an M5, I'd guess.
If I remember rightly, there's an oil blog called 540rat or something. It's a one-page website and very cluttered, but has very interesting data and opinions about oil etc. There's a section about the s65 which you might be interested in reading. |

Frankly, you can't compare a 4-cyl with a V10. 10 cylinder engine with more than double the power is a totally different animal and far more complex to engineering. But Honda is more reliable than BMW, no argument there. S65 has another big issue that S85 doesn't have, main bearings. They don't fail as often as rod bearings, but mains wear badly too and there are already more than enough cases of them falling. It's always the #1 maim bearing that fails, supposedly something with lubrication. This is what happened to project Frankfurt and when they go, the block is trash. Quote:

The E60 platform is amazing, stuff that you mentioned many don't know about! Not to mention no rust issues unlike E39. B7 is a luxurious, silent, torque monster and a very special car that should be experienced as well and I get your decision for wanting to try something else. Thank you! M3 video coming Thursday/Friday. Last edited by Sreten; 05-15-2023 at 06:12 PM.. |

From some technical documents on the E65 where I guess this system was introduced: https://www.meeknet.co.uk/E64/09_E65...20Dynamics.pdf From Page 20 Tolerance Adaptation The damper force is diminished as part of the operating time function. Diminishing damper forces are compensated by current (amperage) reductions which are calculated by the tolerance control. This also individually compensates for mechanical damper wear on each axle. And from page 23 Mechanical wear causes the dampers to weaken over the service life, therefore a running time memory adapts the damper curves towards a harder setting (over time). Faulty dampers must be replaced together (in pairs) on a single axle. After a replacement, the running time memory for the front or rear axle must be reset with the DISplus. May also apply to your Alpina? Last edited by Tommysalami; 05-15-2023 at 11:50 PM.. |

S65 all the way!
Yess!!! Can you please make this the most detailed rebuild on the S65? I love your BMW content-style and am eagerly awaiting the video production of project Frankfurt!

That said, I bet the bearing issues would be solved by a good ~5w-30 oil instead of the factory spec treacle. Remember, more oil pressure isn't better, so long as you have enough! Last edited by Tambohamilton; 05-16-2023 at 04:47 AM.. |
