View Full Version : Broken wasgate Question.

08-22-2010, 02:54 AM
So my infinite boost issue seems to be a malfunctioning old wastgate.
i took it apart today and the diaphragm is ripped, everything esle seemed okay. I ve never taken one apart before though. essential the car is just boosting endlessly. could this be caused by a ripped diaphragm or should i be looking for more issues.

The ripped diaphram will do this. Without the diaphram, that vacuum pot won't build vacuum and pull the rod that opens the waste gate. If you replace the diaphram or the pot itself you should be good to go.
