okay My wife messed the engine up and needing to order an engine. There are two option for the 2.2L engine one had a drilled and tapped air check valve on the exhaust manifold other has none. Anyone able to give me a easy way to check for this.
Do you have the secondary air intake? It would be a pump that runs via hose between your intake and exhaust. If you do then you need the one with the valve and if you dont you wont need it. Make sense?

Its refered to as an air check valve when u look at the motors. Also it says the 8th digit in the vin will let you know if u need it. But when I called to check on engine price, guy told me that the with it and with out it will have an F.
okay I found a sensor that is connected to manifold right before the manifold attaches to the exhaust. It's just under the heat shield that goes over the manifold and looks like it was drilled and tapped to be put in there. It has a wire connection like a sensor would, no Pipe.
