    alternate turbo oil feed

    i never could figure out how to disassemble the actuator.... i know there is a piston in there that moves a rack and pinion so to speak, but couldn't for the life of me figure out how everything was held together. garrett had a thing on their website that said they didn't recondition vvt's...

    alternate turbo oil feed

    Maybe it's getting "just enough"? Like enough to lubricate the bearings but not enough to operate the vane control?

    alternate turbo oil feed

    so far i have tried commanding the turbo to different positions using efi live, and when it was stuck it didnt move. at that point i robbed a position sensor out of another turbo. after that i swapped the actuator solenoid from the other turbo as well. nothing made any difference. so then i...

    alternate turbo oil feed

    i bought a LBZ with a broken crank. rebuilt the engine AND turbo, put it all back together, and the turbo vanes have never responded properly. sometimes gets stuck in a random position. i only put new bushings in the turbo and cleaned all the vanes, did not disassemble the actuator assembly...

    Broken Crankshaft Count?

    im not saying the oil temping issue is not causing crank breakage, but it still isnt a solid thing for me. i work on alot of abused stuff, and for the most part, as long as there is oil in the engine with decent pressure, it's pretty much going to be ok. ive drained pure transmission oil out...

    Broken Crankshaft Count?

    http://www.bobistheoilguy.com/forums/ubbthreads.php?ubb=showflat&Number=2425542 this guy did an oil analysis on his '07 duramax after nearly 9k miles pulling a 15k lb trailer in the 115 degree arizona heat and it came out great. if that didnt kill the oil, what would?

    Broken Crankshaft Count?

    in your opinion, how much oil would a stock duramax with no mods or tune need to stay properly cooled?

    Broken Crankshaft Count?

    not 100% sure of what the previous owners did with my truck before she let go, just going off of what they told me. it was a repo truck with a self-loading wheel hauler bed. i would tend to believe they beat on it pretty good, but it was unmodded. the extent of hauling was pulling cars around...

    Broken Crankshaft Count?

    this is possible. my main focus was the pitting. you can also see that little spot of blue, too. i am ASSuming i quickly checked that bearing and didnt see anything out of the ordinary, but i bet there was some funkyness going on at its edges. could the cap have distorted before the crank let...

    Broken Crankshaft Count?

    ok, so i went out and took another look at the crankshaft that broke. bear with me, it's been a year since i tore it down...... lol the #2 main DOES have some surface irregularities. i blasted it with brake cleaner and wiped it down real good and took some pics. one of the things i began to...

    Broken Crankshaft Count?

    the cranks may be different, but who made the cranks? also, were the lb7/lbz cranks actually different in the area that breaks?

    Broken Crankshaft Count?

    do all those cummins engines out there have trouble with their oil breaking their cranks under heavy abuse? do they have the same problems? 42 broken duramax cranks on this site alone is huge, imo. i may have some new info to post.... stay tuned.

    Broken Crankshaft Count?

    lookee how crisp and pretty the break is..... broke right at the edge of the journal radius's.

    Broken Crankshaft Count?

    all my bearings and crank journals looked fine, imo. im no expert, but i would think there would be signs of crank/bearing contact on at least a few of the bearings if the oil was compromised and the oil pressure had gotten low causing contact. looking at the area on the crankshaft where it...
