yeh was on craigs list. the guy was complaining that it lost power and would die out and choke at 2000 rpm it turned out to be the fuel water separator........... i ended up rebuilding the turbo as well as there was a crap load of play in the shaft. finally finashed all the motor and body work and have been driving it for a little over a month
the trucks running great! good mileage, just put a 3.5 inch stack on today and sounds amazing........ the guy i bought it from picked up another for like a grand and is now asking 4900$ for it .. its rusted to shit and seemed to blow a little blue smoke, id stay away from it......
as for the waste gate, id look into maybe findin another? have u run the motor with this one? tried wiring it closed? the motor also has a BOV so i couldent see keeping the waste gate closed doing any harm....alot of cummins guys i talk to keep there wastegate closed and dont have any problems just watch your boost and temps.
