Sixto,

Those pics are fabulous. Thanks. Couple of questions...

1. Are you saying that I can disconnect the rod at the wastegate and turn it in (CW?) on the controller to tighten it? I believe there is a locking nut inside the diaphragm that may prevent this...

2. Should the wastegate controller move easily? I can move it only by boosting the diaphragm. I have not yet tried to disconnect it.

3. It's hard to tell from your pic... but it looks like the position of the wastegate controller rod attachment at the wastegate on your cleaned turbo is slightly closer to the diaphragm than mine. Mine is turned slightly left of perpendicular while yours looks slightly right. Based on the pic this would make a huge diff in flapper position. Perhaps this is just a spring problem.

I'll try adjusting the gate first and then I'll disconnect the downpipe from the turbo if that does not work.

4. If the problem is not the spring or exhaust I'm guessing the wastegate is gunked and not closing would be the next likely culprit?

5. How much of the turbo needs to be removed to get to that section to clean it?

Thanks for your post. I think this will help a lot.
