I have a 2004 western star with a detroit diesel 60 series. I will be going down the road and my boost will disappear. the shop said to put alcohol in the air system, that it was moisture in the "pea pod?" but since I've done that it has gotten worse. has anybody had this problem with a successful resolution? I appreciate any advice. thanks
You need a new shop.
In the AM get in the truck and pump DOWN the air to about 60, start the truck and go thR side and watch the little piston at the turbo. [turbo-actuator]. The fan will shutoff about the same time as the turbo shaft will rise. You can hear the turbo spool up. If it doesen't, or pulses, or jijjles a lot you have 1 of 2 problems.
#1- you need a new V-pod, found at the lower RS of the engine block by the oil pan rail. crawl under and look for it.
#2- the turbo actuator leaks air, or does not respond to the air supplied from that V-pod.
Air TO the V-pod MUST be greater than 100 psi, air FROM the V-pod TO the turbo actuator will NOT exceed 74 psi. Basically greater pressure then faster turbo speed.
Sounds like you need a new V-pod. careful, I have gone thru 3 on 1 truck to find a good one. They are covered with a 1 year warranty though. Save the receipt.

1986 Isuzu P'up, 177,673.8 miles.
- Hella headlights (highly recommended)
- DOT C-2 back end (also recommended)
- R-12 air conditioner converted to R-406a. Saved ozone and money
- 4.1:1 final drive converted to 3.4:1. Quieter, better mileage but it's a good thing I live in the flat Midwest.
- 9/22/2007, age 21: Still running well when reluctantly sent away for reincarnation, due to body & frame rust.
I have overhauled my Detroit S60, year 2000 I put new pistons, new head, new fuel pump, new injector, new harness, new ecm and it does not work properly. It is idling roughly, doesnt have as much power as before, slow building turbo boost pressure from 16psi to maximum 24psi. Sometimes it works for about an hour just fine, pulls good, boost pressure is at 28psi. Then it starts having those problems again. I checked the air charger pressure and all air fitting on turbo and they are all ok. What should I do?
Hope you install a new cam bolt when you overhauled it. Check 'Cam timing'. If you are off 1 tooth what you have will happen. Let me know if you don't know how to do this. It will require a dial indicator.
