1992 HDJ81 0017607 (just to get that out of the way so we all know what my truck has) Finally getting around to the rebuild. I'll use this thread to document my findings, feel free to contribute! Back in august, I took a vacation to southern california to visit friends / family. Drove 1000~ miles from Portland, Oregon, allllll the way down to the LA area. the truck was absolutely perfect. had been for the 6 months of me owning it prior to vacation, too. Nice smooth sailing at 65-70mph. I'm staying in Crestline in a cabin up on the mountain. I had to detour down the back of the mountain to get to Rancho, no big deal. Warm the truck up, hop in, start driving. I get a good 5 miles outside the cabin, I am coasting downhill in 3rd gear going probably 25 mph. BOOM. truck all of a sudden sounds like someone turned the volume up from 5, to 11. My initial thought is OH s*** I LOST EXHAUST! and I stop and check while it's idling. everything seems intact. truck still revs, is still idling semi decent. i continue coasting a few 100 yards to a flat place where I am safe and blah blah I wait for tow truck etc. truck has no power, revs but sounds like dog s***, is dead. I'm thinking injectors because I roll coal now. either that or a valve is toast. first things first, i'm pulling the intake to inspect the turbo, and the valve cover, to see whats up top. I had to wait to work on it due to contractors and other lame reasons. I'm glad to hopefully get her up soon. I miss that truck. here's two videos of it idling. I just charged the batteries since it's been sitting, silently taunting me.
