I am really hoping that someone here might be able to assist me as I'm currently on a camping trip at Whitefish Montana out from Calgary AB Canada.
I have an issue that has now occurred twice on the same steep and long climb. I'm worried that the next time it happens, the truck wont recover and then go back to normal.
After about say 10mins on a long steep climb, I all of a sudden loose turbo boost and I hear this audible/noisy moan or droan sound coming from the engine bay. I slow to a stranded stop with no power. Turn everything off and get out to verify that my intercooler hoses are all in tack and checks out good. Twice this has happened in the past 6 weeks on the same hill and at almost the same location. I think now that it maybe the differential between engine oil (EOT) and engine coolant temps (ECT) exceeding 15 degrees? However, the DashDaq shows no codes (other that rear tire/axle out of acceptable range) and also the check engine light does not come on. Unfortunately, at the time, I did not notice what my EOT and ECT was.
At the time of incident the trucks geared right down, running approx 30MPH and 30psi boost (I always try not to let it get past 30 when towing). I was running the Spartan
210 (dont like the 210 tow as shifting is TOO harsh - wife boobs jiggle which is good but her coffee spills). EGT's about 1200. So everything was well within normal limits. FYI - 6 weeks ago when it happened I was running the 275 tune so I really don't think this is tuner related.
Anyways, I re-start the truck after about 10 minutes and wala, she goes back to normal. Anyone with any idea?
I'd really like to take this big hill home because the border crossing conditions are WAY better at the Alberta border than at the BC border. Going BC is a bit more forgiving as far as mountainous climbs go.
Thanks Much !!!
