How is the actuator even removed? I've tried and tried on my old turbo, without success.

I'd love to replace the actuator with one that isn't garbage. For example, that can be adjusted externally, and preferably without this particular method of retaining the cap, which is very difficult to deal with underneath the vehicle.

The leak is coming from behind the cap. The problem is the diaphragm. There's only one rubber diaphragm in there. I have two, one is visibly cracked, and the other one is on my car and leaking.

If I had the KKK turbo, I'd have replaced the actuator already in this situation
