I'm sure any mechanic on the list who orders Mitchell books can get this manual. Their copier was having troubles and it's too poor a copy to scan so I'll reproduce the bay window items from the page here. This is what they are looking for on each particular model year of bay window bus: 1968-1969 Type 2 Carb -- PCV, ACL, TP 1970 Type 2 Carb -- PCV, ACL, 2 EVAP, 3 EVAP-VC, 1 TP 1971 Type 2 Carb -- PCV, ACL, EVAP, SPK, EVAP-VC, SPK-DDD, 1 TP 1972 Type 2 Dual Carb -- PCV, ACL, EVAP, SPK, EVAP-VC, SPK-TCS 1973 Type 2 Carb -- 5 PCV, ACL, EVAP, EGR, SPK, AP, EVAP-VC, SPK-DDD 1974 All -- PCV, ACL, EVAP, 9 EGR, SPK, 8 AIS, EVAP-VC, 14 SPK-DDD 1975 Type 2 MFI -- PCV, ACL, EVAP, 2 15 OC, 2 FR, EGR, SPK, EVAP-VC, SPK-DDD 1976 Type 2 MFI -- PCV, ACL, 16 EVAP, 2 15 OC, 2 FR, EGR 1977 Type 2 MFI -- PCV, ACL, 16 EVAP, 2 OC, 2 FR, EGR 1978 All -- PCV, ACL, 16 EVAP, 2 10 OC, 2 10 FR, EGR, 12 AIS 1979 Type 2 MFI -- PCV, 16 EVAP, OC, FR, 13 EGR, 2 O2S, 2 CEC Legend: PCV - Positive Crankcase Ventilation ACL - Thermostatic Air Cleaner EVAP- Fuel Evaporative System SPK - Spark Ignition Control (all advance, retard hardware and hoses) EGR - Exhaust Gar Recirculation System AP - Air Pump Injection System OC - Oxidation Catalytic Converter (vs. TWC 3-way cat) FR - Fill Pipe Restrictor AIS - Air Injection system O2S - Oxygen sensor CEC - Computerized Engine Controls TP - Throttle Positioner EVAP-VC - EVAP Vapor Canister SPK-DDD - Spark Dual Diaphragm Distributor SPK-TCS - Transmission Controlled Spark Exception codes for legend: 01 - M/T only 02 - California Models only 03 - Some models 05 - Some Type 2 08 - Type 2, Dasher(CA) & Type 4 09 - Except 410 A/T 10 - Carb only 12 - Except Type 1 & 2 13 - Federal only 14 - Except Type 1 15 - EPA authorized removal on some models. Check for door label. 16 - Vapor canister type I think there are some discrepancies above but that's what the book says. After the visual inspection the first thing they check is the timing. It can be at most +/- 3 degrees. Anything outside of the range and they fail it right away. The RPM has to be within the correct idle range as well or it will fail right away. Take a good gas cap with you with a good rubber seal. They hook it up to a pressure tester on the last test with a dark blue adapter to see if it seals. The emission test is not done on the dyno for some reason. They leave it in neutral the whole time. At least for 1978, they test %CO2, %02, HC(PPM) and %CO but not NO(PPM). -- Richard 1978 Westfalia CDN Cupertino, CA
