WELL FOLKS! This is probably the longest teardown I've done as far as time required in the last several months. 8 hours of filming over 2 nights, 8+ hours of editing, 221 raw clips has resulted in what I hope ends up being an enjoyable video for you all. I don't ask for likes or subscribers because that's not my style, I try to earn both of those organically.
If you ask me what one of may least favorite engines is, this is on the short list. BMW's N63 hot V 4.4L Twin turbo V8. This engine, while an engineering marvel, is probably the worst engine BMW has ever made. They cost a small fortune to keep right and have RELENTLESS fault codes, expensive components, and many problems are never truly fixed. I'd say the overall life expectancy is 80-100k miles with average care. Pretty dismal. I could NEVER recommend anyone purchase an early N63 powered bmw, 2008-2013 are the non TU, or technical update, and are plagued with the most issues.
This particular N63 is from a 2011 750Li with 127k miles comes courtesy of Ryan at Smitty's Automotive in Hyrum, UT. For most cars, you'd consider that low for being 12 years old. This engine had multiple problems, the last of them resulted one a catastrophic failure which wrecked nearly half the engines worth of parts or more.
Why on earth am I doing these teardowns? I own and run a full service auto salvage business in the Saint Louis area called Importapart. Part of our model is buying blown, core and unwanted engines and dismantling them to resell the good, usable parts. We do not rebuild engines, we merely supply parts to those who do.
I really hope you enjoyed this teardown. As always, I love all of the comments, feedback, and even the criticism. Catch you on the next one!
