TTAC Commentator Nate writes:I’m working on a 1979 Dodge D200 with 360CID V8 4BBL carbureted engine, automatic trans, A.I.R. pump, EGR valve, and charcoal canister for the fuel tank hydrocarbons. The underhood factory decal says “California Medium Duty Emissions” and it has no catalytic converter from new. So here’s my situation:

• All hoses, pipes etc. are there and all valves etc. are working .
• The A.I.R. pump works but the diverter valve has failed (vacuum diaphragm leaks) and is in the open position so it’s always blowing fresh air into the exhaust manifolds.

Is it likely to pass the emissions test like this? I took my Ca. smog tester license training in 1984 and honestly only remember bits and pieces. So far I’ve not been able to find a new or good used diverter valve. Please advise!
