So the Wastegate was not exactly "gating" turns out the diaphragm was ruptured. Boost spikes to 20+ psi (I was lifting at 18-ish when the overboost buzzer went off), which probably is why the head gasket blew initially.
I suppose I could have spent $60 on a new wastegate actuator, but... yall know me better than that.
I happened to have a Volvo wastegate actuator in the garage, so I worked on adapting it.
You can see the brackets are different. The rods are also different lengths. Also the end that attaches to the wastegate is adjustable with a thicker flange than the non-adjustable stock one.
The stock wga was attached to the bracket via spot welds. I drilled them out.
I then cut the non-flat part of the Volvo brackets off the WGA.
Here they are before "hot glueing" them together.
At this point I got out the welder and forgot to take any more pictures. Bad Matthew, bad.
After welding together and installing, I found I needed to grind about half of the thickness of the "eye" that connects the wga arm to the wastegate. After that I was able to put on a new c-clip and go for a drive.
It works!
Total spent:
$3.22 for a pack of c-clips.
