S65 engine temp gets extremely hot even at high speed circuits like Suzuka, can't imagine what the bearing temperature would look like doing 1-5mph with barely any cooling. This one was a VANOS chain but can't imagine the bearing condition would be good with this usage either.

threads like this make me feel better for doing my RBs right after I purchased the car, not doing donuts, or revving the engine while cold, or drifting the damn thing lol

230k Kms, no issues ever! Change my rod bearing at 160k kms for the hell of it. They came out pristine btw.

I was looking to purchase one 10K miles, pristine inside and out. Owner claimed no person had ever been in the back seat. However, given the car he was replacing it with was a Porche GT3... I'd say more than likely his had seen track time. You have to ask yourself. How much of the engines life has likely been spent above 5000rpm. The M3 that I did end up buying, the M-drive came programmed on Lv 5. That lets the engine hit 8000rpm routinely before upshifting (upon full-throttle). IMO I see no need for that, Lv 3 still gets you to 7000rpm that's plenty power/noise to enjoy without unnecessary motor/oil stress. So for me, that's a warning sign and am all prepped to do rod and main bearing replacement in near future. |

Furthermore I think the point of the engineering if this car is to rev it all the way out, because that's where the power is. They could have made a low revving V8 but they didn't. There's plenty of turbo cars that give you nothing more when you rev them out and are more fun in the mid range, but that's not the s65. I mean it's your money and your choice on how to drive the car you buy, but I feel you are misunderstanding this platform and what is and isn't harmful to it. |

Thanks , but unfortunately your tag is broken and so I didn't get a notification.
I don't know how to tag either, can someone tell us? Btw folks, feel free to tag me if ...... when the next engine failure happens, I rarely look through all the new threads but I do get notifications (hmm, I need to activate email notification[edit]I had anyway, but it doesn't work!). Quote:

But often people mistake the moderate wear on the LCI bearings as pristine, when they're not.
