The air check valve on the exhaust manifold pipe (NOT the check valve at the air rail) has rotted in half, and I don't think I can remove the remaining piece. I'm thinking of cutting off and capping the small (1"?) exhaust pipe extension that the check valve mounts to (rather than get a new exhaust manifold pipe).
I would then leave the air pump inlet pipe open to atmosphere (I still have all emission control equipment). The only effect I see is that air pump supply won't receive the heated exhaust air - just ambient air in the engine compartment.
I am in New Hampshire where they don't require emission testing on a vehicle this old.
Anyone see a problem with this approach?
