Idle control and maybe intake leaks, how to for swapping in a 52mm Vanagon throttle body Options

[VaccaRabite]

I broke the plug to my idle control valve. I bought a new plug housing. Easy. But I’ve had a devil of a time finding the right socket pins for the housing. Several weeks have been stalled waiting for 80 cents worth of pins that show up and are the wrong size.

So, knowing the 914 has to drive next weekend, I went full DACO and soldered a pigtail of wires into the ICV and then crimped them into place.

About to find out if it works, and will continue to work for a couple weeks while I sleuth out the right sockets for the plug Wish me luck!

Found an air leak on the throttle body with my homemade smoke machine. The cellophane is what I used to block smoke from going from the TB into the air intake box. The first time I did the test smoke just started rolling out the air intake box. Not helpful.

The leak seems to be on the shaft that controls the butterfly. I’m guessing this is the source of my intermittent leak and high-at-times idle?

Is this fixable or do I need to replace the TB?

Also I’ve removed the IAC valve from the engine and gotten it to where it will idle fine once warm. Then it will suddenly want to idle a good bit higher I guess as the throttle shaft moves around.


Here is a pic of the smoke machine I made the other day.
