Replaced Egr and turbo hose @ 95k, 135 U-joints and Rearend fluid, Turbo Stand pipes...+ 4" exhaust ( Best move for $$$) Tranny fluid @ 35, 70, 97k, 8 inj and High pressure oil pump and EGR Cooler along w/ oil log o rings @ 175k... for reliability purposes after loosing 1 inj. Great truck, no oil useage..... Change oil evy 5k...This weeked it started blowing off turbo hose (TOP) I put on new one w New Clamps, but can't keep it on.... No real reason, flat land///Hill///just blows off, may last 2 min may last 5-6 hours....What could be the reason for this, as for I'm tired of living in the engine compartment (LOL) The seat is uch more comfortable!!! Thanks MDE--FBT. ++++++++++++++++++++++++++++++++++++++++++++++++++ +++++++++++++++ K I finally got home and pulled radiator, pulled Cooler, I took end off of cooler and washed out unit completely.....really not alot of film inside. I resealed and installed cooler radiator....Went 1/2 mile up the road and the damn thing blew off again......... Where can I look now????? Now at least i know it's not a oil build up in the cooler.
