3 Turbos, high oil temp
Hoping for some insight, I have had some recurring problems that we have still not resolved.
My truck has had the lag and sluggish performance since purchased (6500 miles). Taken to dealer and explained as detuned engine, and that's just the way things are. This was/is hard to accept as this is often dangerous in traffic.
Although aggravating I can manage to deal with it. ... On to the present problem.
At 34K turbo bearings failed. shortly after DPF was replaced as Restricted. At 48K CAC Hose Blown off with clamp failure. At 49K turbo 2nd failure again being bearings.
At 77K lost power and boost dropped. Called for road service and was told would tow to dealer Monday morning, decided to limp to motel. When pulling back onto interstate, power was back, but after 4-8 miles it would choke down again. (Acted just like fuel filters) Found that I could pull off and let it idle a couple of minutes, then I could take off and go again with same result. Found a dealer monday where they tried to find problem, (Serviced and Fuel filters changed) test drove without load or trailer and signed off as okay. 50 miles south of visit, and after hours, problem returned. Limped all the way home while traffic was less. Took to my preferred dealer, which have been Great. Test drove without trailer and everything seemed fine. Brought my empty trailer and problem showed up on long hills. All vitals looked good on computer (fuel pressure, exhaust restriction) Diagnosed as Turbo seizing.
Turbo and CAC replaced (other dealerships did not replace CAC) (( inside of both were full of crud)). Had good hopes of all being well now,,,,but,,, Once loaded truck topped out at 60 and boost dropped again. Same indications, could run strong then have to pull off and idle to let it catch its breath. All the while I had been watching gauges. but for some reason I decided to look through monitor screen and found Oil temp was 267, normally about 205-210. Will be back at dealer (Again I must stress, have been Great) tomorrow and tell them this new revelation, but was looking for any ideas from the forum family.
