I have read all the boost related posts I could find, and did not see a picture of the solenoid that was used on the 89 SC. Can someone post one up? I have a 3.8L SC in a F100 and I cant seem to locate this component.
The reason I ask, is it appears I have been running without the SC kicking in. I unplugged the by-pass actuator vacuum line and then it closed the by-pass. Voila - boost! It opens and closes with engine start/stop, But nothing in between. The valve isn't sticking and the actuator does not leak.
so I am wondering if this solenoid is needed and missed when I reassembled the engine into it's new home.
BTW, I currently have the actuator vacuum line attached to the common vacuum tree. Is this the culprit? Does it need to pull vacuum from somewhere else? Would this eliminate any need for the solenoid?
Puzzled,
John
