There is an arrow located at t

There is an arrow located at the bottom of the air injection system cut off valve ( it's the round plastic valve with the vaccum tube attached to its top located at the top of the clutch housing) on my '85 308. When installed, should the arrow point toward the drivers side of the car? This would indicate air flow from the air cleaner box--is this correct? What could happen if this were installed the wrong way?

The arrow indicates the flow direction. I think it may also be a one way valve as well, so if reversed under certain conditions you would not get the natural pull of fresh air due to pulsations and may have blowback.
I think.

Doesn't the owners manuel have a picture schematic of the system with arrows in the diagram?

Hi Mr. Van Dyne,

Out pokin


Hi Mr. Van Dyne,

Out poking about under the decklid (hood?) the other day remembered your question.

My (328) valve arrow is located on the rearmost side and points towards driver's (LH) side of car. Uncertain what would occur were this installed backwards; it's a vacuum-operated (via solenoid under LH wheelwell) valve that "opens" when car is running to admit air into exhaust system. Probably would admit less air & possibly influence O-2 sensor readings & FI operation.
