The car belonged to a used car lot and appeared to have a junkyard engine because there were writings on the engine. The car lot wanted it fixed. I figure they must have got the car for next to nothing, tried to put a junk yard engine that had a bad timing chain. I asked about the oil used etc but they didn't have any history on it. Why would a late model BMW v-8 need a timing chain or new engine?
It is 4.4ltr N63 engine. I highly doubt 6k is only chain. That engine has a lot of issues, mostly due to the fact that turbos, who are running ridiculously hot, are in the V bay. Also, operating temperature of that engine is 110c. I would guess that together with chain, they are changing: valve stems, turbo oil lines, cooling lines and not uncommon due to lack of attention, turbos.
Problem with these engines is that they see a lot of city driving and they are not design for that at all. N63TU version addressed these issues and so far proved to be pretty reliable.
I'm glad you are at least giving good information on some of the German engine issues. It's better to help people than to pretend things are good most engines out there.
This engine has serious issues. BMW had Customer Care Package (CCP) for owners of these engines, where they changed valve stems, oil and coolant lines to turbos, and in many cases turbos. Still, sometimes issues would pop out again. This engine is pure and simple a garbage. Perforance wise, it is unbelievable engine, but it is like they strictly focused on that, disregarding issues as product of complex design.
