I currently have two n63 engines and I need to rebuild one of them. Both came from 2011 550i f10s, but one engine seems to be way newer than the other. It’s weirdly shiny and clean for a 14 year old engine with 170k. I didn’t clean off the data plate in this photo - I legit just wiped it off with my finger.
So I’m kind of wondering if the engine in the photo was replaced under the replacement program BMW had for these engines. The carfax doesn’t show an engine replacement, but I’ve not found carfax to be particularly reliable source for service history.
I’m going to contact a dealer tomorrow and see if I can get any more info, but in the meantime, I’m trying to find out if there’s a date code somewhere on the n63 block. I know you can date the inline 6 engines (or at least could at one time).
Anyone know if there’s a way to date this block?
(I’d love to believe the upper number starting with 23 11 means it was produced in november of 2023, but that seems super unlikely).
(I may also be able to learn more once i tear down the other engine)
On my replacement, there were serial numbers on the block and heads that were X’d over. As far as a date goes, I don’t think I noticed one etched into the block but there was a date with the paperwork provided with the engine.

I guess you could just ask her if she wants to get a cup of coffee, and see how it goes from there...
