Stranded in Utah
My girlfriend and I are moving from Sarasota, FL to Los Angeles, CA. We've planned a lengthy road trip to travel the states on our way. We've been on the road for about 5 weeks now and haven't run into much trouble. The truck is an early '99 F-250 7.3l. We have a 1,300 lb camper in the bed and a 13,000 lb tandem axle trailer following us. GVW is 23,500 lb.
I noticed the truck overheating as we came out of a lengthy and steep pull in some canyons outside Moab. As soon as I saw the temperature gauge rise I pulled over and waited for it to cool. With another climb ahead I knocked it in 4low (with the hubs unlocked) and crawled up without issue. I then put it back in 2high and began our descent. I immediately noticed a loud knocking sound, large loss of power, and saw white smoke billowing from the exhaust. We stopped and called a tow truck. $500 later and we're in Richfield, Utah.
I need help diagnosing the problem. I'm mechanically capable and have my tools with me but I'm not sure how to determine the issue.
Here's the facts:
-Extreme amounts of white smoke billowing from the exhaust (like a fog machine!)
-no noticeable sweet odor or taste in the smoke
-no noticeable milkiness in the oil
-severe power loss at high rpm
-loud and disorganized clanking sound from the engine (or possibly the turbo)
-engine didnt seem to have problems cooling after overheat
I believe its most likely the turbo gone bad but i dont know what to look for. can anyone point me in the right direction? i really appreciate any help in advance-
