P.C.V, T.A.C (thermostatic air cleaner) Evap, A.I.S (air injection system)Does anyone know what the stock smog stuff is on a 78? It cant be that strict for that year. Thanks for all the help. Maybe i"ll check out that green sticker thing too.
I just ran my '78 through a test only shop in Benicia and got jacked on teh visual. It tested great on emmissions, but I got nailed on 2 hoses, a fuel leak at the carb and evap leak.Well the required equipment has to do if its a 49 state or not like others are saying. Whatever the truck came with it needs to have still. Like others have said emmissions were pretty lax in 79. Most shops dont look to carefully at equipment like smog pumps, cats, etc. The place I smog at had a hard time figuring out how to open the hood so they had no clue about anything else. I dont have all the factory equipment on my truck but it smogs fine. The numbers out the tail pipe are what most smog shops look for. I know a good shop in San Jose that wont care about anything but the numbers.
