Was just on the phone with my mechanic- seems one of his customers just blew his forth 6.5 TD motor. I found this a bit odd, and inquired more about it. HE says it looks like the camshaft broke, on this new gm crate motor. On the last one, it looks like it was oil starved. So of course, my mechanic calls the motors "junk" and "under powered". I personally like this motor a lot. I dont know what caused the owner to crack a cam, he says the engine isnt used heavily, (3500 dually with utiltiy bed). And 6 blown turbo's seem very odd too. Any comments?
