Air Injection Tube: Testing and Inspection
Air Injection Tube
There is no periodic service or inspection for air injection tubes. However, whenever the cylinder head is removed from in line engines, or
whenever exhaust manifolds are removed from V8 engines, inspect the tubes for carbon build-up and warped or burnt tubes. Remove any carbon
build-up with a wire brush. Warped or burnt tubes must be replaced.
