She said she had to do the valve stem seals after 100k miles, but otherwise it was OK.
If I had one with a replacement engine, I don't think I'd worry too much in the short term. Likely that you'd start having other headaches before the new engine starts acting up (electronics, actuators, etc. )

Yeah, lots of hit or miss I'm finding. So as a second or third owner, would I be eligible for replacement if the N63 fails the test? Haven't seen much said about that.
All these failed engines have me leaning towards the 740li. I really wanted the V8.
