I know this isn't an open thread, but do I still need my hifi? I haven't had it hooked up in like three years, all the components save the turntable are from the 80s, and if I can replace it with stuff that sounds as good and are physically smaller, I think I will. Basically big floor speakers and a large receiver that needs to be rebuilt.

My bet is the 6.2s are nuking because of the following...GM recommends but does not require high test, so most owners don't spend the upcharge but still cane their trucks regularly which creates knock, timing is pulled but the fueling is slow to respond so you get a momentary rich condition...GM spec'd 20w oil because someone thinks consumers give a shit about the fuel economy their $50k+ 5k+lb V8 vehicle gets so they shrank the bearing clearances down to basically nothing which leaves no room for error...They also switched to direct injection to eek a few more trivial improvements in efficiency, which introduces fuel dilution which drops that already low viscosity down to almost water and as a final act of trying to make an orange an apple, they added stop start so the engine goes through more low oil pressure rotations than it should...next thing you know you have a window where one shouldn't be.

Regarding the 2.7 TURBOMAXXXXXXX, it is crazy to me that the dumbest half ton truck engine idea is actually proving to be the most reliable, closely followed by the now seemingly sorted but still overly complex babymax diesel. Signed, a Gen V 5.3 owner who shorts the recommended oil change interval and crosses his fingers every night hoping to catch a lifter failing before it nukes the rotating assembly in his air hauler.
