How to service the Secondary Air Injection Check Valve for Bank 1 on Chevrolet Corvette?

Service of the secondary air injection (AIR) check valve for bank 1 should begin by removing the check valve clamp then separating the Air Hose from the check valve after ensuring engine coolness to avoid burns. The service begins by removing the check valve from the air pipe followed by extracting the left air pipe from the manifold. A proper check valve operation test requires installing a Vacuum Pump to the air pump side nipple and pumping it to 10 in hg while monitoring the gauge; the valve requires replacement if it drains to zero pressure in 5 seconds. Connect the check valve to the air pipe while tightening both to 23 n.m (17 lb ft) and secure the air pipe at the Exhaust Manifold with 20 n.m (15 lb ft) torque. To complete the installation process connect the check valve clamp onto the check valve and Air Hose.
