7MGE Engine rebuild

Took a while to figure out where the two VAC line brackets went till I discovered they attached to the outside of the AIR Chamber bolts. One on the left and one on the right. The Blue VAC switch also attached to the AIR chamber. There were some grounding straps with 16 gauge striped wires that I was not sure where they went so I finally attached to the AIR Chamber as well. Not sure this is right since aluminum is not the best electrical conductor.



Mounted the AIR Chamber after installing the Vacuum controlled AIR VALVE. Before I installed the AIR Chamber, I installed the EGR Valve to the back of the head to get it lined up with the port on the AIR Chamber so they could be all bolted together at one time. Would have been very difficult to install the EGR after the AIR Chamber and get the gaskets on.



With the Air Chamber on, I could get the Cold Start Injector and IAC valve on next.



The IAC connects to the pre-installed hose from the underside of the Intake runner. One thing I found is that if you use RTV on the hose fittings, they slide on real easy with the spring clamps already in place so you don’t have get in there with pliers to finish connections. The RTV seems to set up pretty secure the next day. Hope it holds.
