New Turbo on the way? & sticky Actuator getting sorted?
this makes it a little more impressive and thank you for helping document your struggles & solutions on the forums! ❤️
pretty sure its a stuck actuator rod on the primary turbo. I checked all my solenoids they all click.. ill admit I cant exactly tell if their working due to not knowing their inspec multimeter numbers.
but all seem to click and allow air to pass thru including the one in the passenger fender. replaced all my check valves (boost filters) and I was still getting code 66. So I tried articulating each arm on the turbo and took her out for a test drive. I was able to get about 8 psi. Was like sweet tried one more pull and she went limp. digging online people say thats popular in turbo cars so the over pressure doesn't blow the engine. (I.E. actuator rod isn't opening to allow release in pressure.) Tried one more time on primary and now I believe its stuck open as there is no top end turbo at all. its all engine but I can hear my bottom end turbo spool and feel the torque. So pulled the turbo and ordered a new one a VF25 its a primary from a 98 auto GTB so like 2 or 3 less psi but it works so theres that.
