yep, that sounds right.... low boost and slower to boost
must investigate more
 
Don't forget your valve set is done cold. Are you leaving the truck at the shop overnight when you drive it there?

@Greg: right. I don't know yet. the valves may not get done till I"m back in the States.
I've got 3 weeks to make my house rentable, make my car driveable, make my dog suitable for canine travel, and actually drive 4,000 miles to the Bay Area.
The first week is gone: getting someone to work during Holy Week in Central America is nearly impossible.
So dropping the truck for 24 hours is looking like a challenge... I'll have to see if I can make it work.

re: the wastegate. I've just got to try it out and see what happens. I'm inclined to let the greasemonkeys deal with it, I have enough other things on my mind.
 
Hey everyone--

I'm faced with trying to rush the valve adjustment before getting on the road for a straightforward 4000 mile drive

or leave it, and do it when I get back to California

What is the vote? Do it now despite very high inconvenience, or let it ride for another 4,000 miles?

I would not rush anything just before a long drive period! I vote for leave it and drive with some reserve and adjust on the return without delay.

I read your blog. So, the root cause of your loss of boost was a cracked fuel line fitting at the filter housing, not the turbo. Is that correct? And the resolution was to replace the filter housing, fittings and line?

[For completeness on this very informative thread, I thought it useful to post the end solution for those in the future that will use IH8MUD to troubleshoot their loss of boost ;-]

'Spilled milk', but your turbo shop should have figured that out on day 1...but you know that.

Glad you fixed it!

(sometimes, especially on public forums with opinions flying around, its easy to go off on tangents and loose sight of what is logical)
 
Yes:
Symptoms were low boost
I pulled the turbo to see if something was wrong and saw the broken blades, so took it to the turbo shop.
They didn't have the truck until after the turbo was repaired... so it isn't their fault at all.

After the turbo was re-installed, we still had low boost from air in the fuel via a cracked fitting on the filter.

Final fix: replace filter, filter housing and fuel lines.

for the record- the busted turbo vanes required replacement in any event. so the filter giving me symptoms was actually a blessing in that it drew attention to the turbo.

other than time and some money spent, this whole thing worked out well
