hi rae...
a LOT depends on the nature of the the failure.
turbos need some warm up time and some cool down time,
after working hard.
they also need GOOD CLEAN OIL.
many things can go bad related to the turbo (see the list of parts and pick some)
but typically it's heat, coking, poor lubrication, or rupture somewhere along the air system (clamps, hoses, valves)
bearings can fail in the turbos 2ndary to heat, no cool down, and oil issues.
the wicked HIGH exhaust temps and the fact that this EXHAUST gas is recirculated into the turbo (for emissions) REALLY stress the turbo parts.
my understanding is the exc' has some bits that are different than the truck 6.0s.
for example space limits the down pipe so it's smaller.
the turbo is also slightly smaller or at least the air chambers for it.
___________
a failure should "throw codes" but the mechanic also needs to understand HOW to interpret those codes.
visual inspection by the mechanic adds to the computer info, don't rely on ONE without the other...
you SHOULD be able to get a printout of the diagnostic info and the fault codes...
any powerstroke trained mechanic can interpret the codes, but that's only part of the picture.
the turbo was part of the original 100,000/5 year diesel warranty but you are past the time limit now.
___________
get the codes and the mechanics explanation of WHAT has failed, the expected parts to replace and so on...
then join the yahoo POWERSTROKE GROUP...
the group is here...
PowerStroke : '99+6.0/6.4/7.3 Diesel S-Duty,Van &Excsn
after joining, post your question, something line...
6.0 diesel excursion turbo failure help...
begin by describing the vehicle basics, then describe the problem...
then offer up ANY info from the mechanic...
the fellow who reads/answers most questions is charles ledger?
he's a master mechanic and extremely versed on this drivetrain.
he may ask you for more info, and if that happens SUPPLY answers.
he does an amazing job with cyber solving and explanations.
others may offer up useful info too, but pay attention to his replies.
__________
preventing turbo failure revolves around CLEAN fresh oil, proper warm up/cool downs...
paying attention to the BOOST psi, avoiding LONG periods of idling and so on...
luck is also needed since there are some parts on THIS setup which are acknowledge issues.
let us know how it goes.
cheers
