  1. If crack hose gives overboost what is actually happening? Is it not enough pressure to retrack the actuator or to extend it?
  2. I would then assume the wastegate's purpose is to dump excessive air pressure out of the system via the exhaust manifold to maintain the correct turbo charge depending on the RPM's? If this is correct where is the boost pressure sensor located that would detect an overboost condition? Somewhere in the air duct to the intake port I pressume.
  3. Just so that I'm clear, 1. Air pressure is generated by the exhaust turbine which has another turbine attached to the same shaft that controls intake air that travels into the intake to create the turbo effect 2. At the same time some of the air travels into a passage way carried by the hose to a diaphram called the actuator which has a mtering rod controlling a valve called the wastegate. 3. It has fine adjustments that determine the volume of air to be exhausted through this valve, the waste gate. I think what GRP151 was referring to is lubricating oil for the turbine can accumulate from a worn turbine shaft may pollute the hose to the diaphram and restrict or change the actuators performance?
  4. What controls the boost pressure sensor? Pressure, vacuum, electrical? Do you have a picture please?
  5. I'm still having intermittent P0238 code problem. It goes into limp mode. After a short or long drive the engine light will come on, there is no consistant pattern that I can find, my OBDII scanner indicates this error code. Sometimes I will clear it with the scanner and it will run fine again other times I will shut off the motor, let it sit for a while, and the engine warning light will no longer display a problem, then it runs fine again. I cannot assume it is the waste gate adjustment or the wategate hose if it is intermittent. Why would it corrects itself or activate a code is confusing? Why would it go into limp mode? Either it is either broken or it isn't? What controls the wastegate actuator? Is it vacuum actuated or pressure? So many questions and no one to answer.
  6. Okay Got it! but what does...On a good thermostat you should be able to suck yourself onto that barb? ???suck yourself onto that barb???
  7. I found an image of the thermostat. I assume it had to have been cut open and does not disassemble easily. I m having some difficulty understanding your barb explanation. What does " Barb where water runs out goes straight to radiator " mean?
  8. I read somewhere on this site that blowing into thermostat inlet and covering one end to check leakage but I cannot remember the details. Does that make sense?
  9. Just curious. How did you have the injectors tested? and shouldn't diesel fuel be pissing out of the removed glow plug hole when you cranked the motor or when it ran for a few seconds?
  10. Uncle passed away 2 years ago, my aunt said he sold it for $65,000, that's all the info I got on it. Sorry!

  12. My uncle had a 1968 404 convertible. We had a lot of fun riding in it when I was a kid. Brings back memories! I loved thatr gun barrel gray colour
  13. Replace the thermostat with a 451 type bleed out ALL the air and everything will work perfectly. That is what l have concluded from the restrictor/constrictor mods on this site.
  14. Did you solve the problem? Was it the actuator rod or chaffed wiring to the gear position sensor?
