Speaking of improvising.

A friend called me late one night with a serious issue with his waste gate.

Seems the diaphram had gone south and the waste gate was hanging open.

This was quite disturbing as the EGT's were going through the roof while pulling grades. (He was towing a camp trailer 20ft ??? )

The issue was, what could be done out in the middle of nowhere???????/

I advised him to rummage the tool box and see what he had available.
A few minutes later he calls back with a list of items available.

1 Bungy cord, YESSSSSSSSSSSSSSSS Found laying alongside the rig at the truck stop while getting some chow.

Hooked to the wastegate arm and tied off to a suitable spot in the engine bay, the little rubber band got the job done quite well, and with a little adjustment worked for the remainder of their trip.

A few SES lights due to excess boost but easily reset on the fly with a restart.

Or some wire and a spring will do the same trick, if you aren't worried about looks.

The 92/93 actuators are not vacuum controlled. Spring tension only. 94 and later are vacuum/PCM controlled. If you use a vacuum actuator, you will still need vacuum (the vacuum is the spring, so to speak).

Has anyone modified a 94-95 to work with one of these? And if so do you have any pictures of what is needed or possibly a good write up?

I picked up a 94 Suburban yesterday, so maybe if I poked around long enough I could figure out what needs to be done, but this is my first diesel, and my first turbo.
