Lexus LS460 1UR 4.6L V8 Blown Engine Total Teardown How Did One Of The Most Reliable Engines Fail

My name is Eric and I own and run a full service salvage business called Importapart located in the Saint Louis MO area. Part of our model is dismantling and selling parts from rare and niche market engines. I've torn down everything from an LS7 to a Renesis rotary engine. There are several videos to watch! Check out my playlist of engine teardowns here: /playlist/PLIYwo7JlrVQVg32JL-r4H7dfMxMqzWlVa In this video I teardown an engine from a 2007-2010 Lexus LS460 or GS460. After a carfax this is a 2008 GS460 Engine, from a wrecked car that went through the auction. Unfortunately it was so long ago I can't get any details other than it has more than 150K on it. This teardown went pretty smooth though I admit the headbolts were VERY tight, and being a triple square made getting them out in a timely fashion a bit challenging. Also, I didn't get catch it on video, but the missing bridge chain guide was in small pieces in the pickup, jammed around the corners. Its likely one of the causes for the oil starvation. Overall I really like the design of this engine, and I think they're pretty reliable considering there isn't a huge market for used engines... a telling sign of an engines reliability. If you'd like to buy parts from this engine or other engines I've town down, please email us at Importapartsales@gmail.com. Thanks for watching! -Eric
