I recently purchased a 1980 Ford Pinto Station Wagon with California Emissions, Automatic Transmission, and A/C.
Date code on the door jamb sticker is 07/80.
I purchased the car to fix it up and have a nice retro daily driver.
When I purchased the car, I did not realize that so much of the Emissions equipment had been disconnected, and where I live, the car must have all the original emissions equipment to pass the smog test.
So I have purchased many Ford manuals and other publications to try to figure out what needs to be connected where, and what is just missing.
My questions are more about what I may be missing.
First, my exhaust manifold is cracked, so I went searching for one, but I found two possibilities. The exhaust manifold currently on the car has three ports. One is a 90 degree fitting that connects to the EGR Valve via a pipe. The second has a One Way Check Valve attached to curved pipe. And the third hole has an Oxygen Sensor screwed in it.
My first question is in regards to the Oxygen Sensor. Not only is mine unplugged, but there is no wires anywhere on the wiring harness with a plug to plug into the Oxygen Sensor. Did someone not only unplug the wire but then cut the wires from the harness?
Or, did the 1980 California car not have an Oxygen Sensor, and someone changed the exhaust manifold at some time, and put the wrong one on?
Next question is in regards to an Air Pump.
Did the 1980 California Emissions car use an Air Pump?
My car does not have an Air Pump currently.
The curved pipe One Way Check Valve is attached to a Three Way Diverter Valve. The bottom port of the diverter is attached to a pipe that runs parallel to the exhaust pipe, and the front port is plugged.
If my car should have an Air Pump, what else and I missing between the Pump and Three Way Diverter Valve?
I would like to return my car to stock condition, so if anyone knows where I could see photos of a 1980 California Emissions car, or if anyone can help with my questions, I would greatly appreciate it.
Thank you everyone in advance.
