My TC with the stock IHI has been overboosting, so I went ahead and got a Gillis valve to replace the stock BCS and a real boost gauge. However, that did not fix the problem, so I started actually trying to figure out what the problem was. After searching the board I found a number of posts on the subject, they can be generally summarized by this one: http://natomessageboard.com/Forum1/HTML/010555.html
I've hooked a bicycle pump and a pressure gauge up to the wastegate actuator and it will hold pressure and the wastegate control rod moved by a few thousandths of an inch 10 PSI are applied. I can feel the actuator rod is still connected to the pivot arm but I can not, for the life of me, figure out how to disconnect the pivot arm with the turbo still on the car. This may be a moot point anyway since the wastegate is almost certainly stuck.
This leads to my next question. Is there anyway to fix or replace the wastegate on the turbo?
Thanks in advance,
