[QUOTE="Trickymissfit, post: 737432, member: 25383"] I worked for Allison Transmission for 34 years, and I've certainly seen my share of junk over the years. We had about 14 different dynos in test cells with everything from a gas turbine in them to a V16 deisel. Every brand name you can think of, plus a few more to boot. The only motor we never blew up was a Cummins, but we did wear some of them out (700K miles on them). I've seen piles of Mercedes deisels out back waiting for them to pick them up. Same could be said with most all the major brand names. Repaired every form of block that Detroit ever produced (test stands and dynos are kinda brutal on engines). Watched CAT quality go south over the last five to seven years (a real shame). Watched the guys in the test cells literal fill up scrap tubs with engine parts out of Asia. Watched the evolution of the Duramax go from pure junk to a fairly good engine over several years of redesign. Watched them haul pallots of these motors in one door of the test cells while hauling out pallots of blown up Durmax engines out the back door (they started out lasting about 72 hours on the dyno with a catstropic block failure). Saw the samething with the Ford deisels as well I might add. The test cells we setup for the M1 tank power pack are probably the nastiest ones on drive trane parts I've ever seen. If it's gonna break; they'll break it! Have never seen a gas turbine fail than God!! Have heard the horror stories. But have seen rods hanging thru the sides of Detroit V16 engines a bunch of times (that's a really expensive engine failure by the way). We switched the deisel engines in the test cells over to Cummins V16's and I never saw a failure. But right next door is the samething with a gas turbine running 24/7 as well. I did witness an X1100-5 shift into two gear ranges at the sametime. My ears rang for a solid week! The guts came out like powdered metal.
