About Skip Bollinger
Expertise
Heretofore, I will NOT answer any mechanical question. I am not qualified and can only offer speculations. You are better served by others that are true Techs. With that being said, please only ask about parts and locating obsolete Auto Parts. Thank you. I have the ability to locate quite a few mechanical parts for American made vehicles fron the 1900`s to present. Some are OEM and some are aftermarket. This would include engine, brake and chassis parts. Body parts and trim are VERY difficult to find but you may inquire. If you need assistance in repair, I have illustrated books for major American manufacturers that show some illustrations BEFORE 1974. If needed, I can supply repair manuals for your specific vehicle. PLEASE REMEBER I'M A PARTS SPECIALIST, NOT A TECH!! Thank you.. Skip

Question
why does the turbo waste gate open when i excell slow

Answer
Rick,
  I am NO Tech and when it comes to Diesels, I'm an idiot but I will offer this thought.
  A turbo is designed to make horse power / torque. When you decelerate (I imagine this is what you meant by "excell slow"), the turbo is not needed and the waste gate opens to purge the pressure from the intake charge from the engine to reduce or eliminate any torque or horse power. It is like a "turbo brake", I would imagine.
  On a side bar, I have seen signs on roads going into small towns that say something like "No Engine Brakes". I asked around and what that means is that, on diesels in some applications, the driver can flip a lever and it holds the exhaust valves open to reduce the output of the engine, however VERY noisy.
  I hope this may help. Like I said, I'm NOT an expert or even a novice in this area. You might want to ask someone else to get a better answer. I just thought I would give you my speculations. Good luck.
