General Smog Check

What smog parts required on a 1979 Chevy truck with v8 350 engine.

Which smog or emissions parts are needed on my 1979 Chevrolet pickup truck. It has a 350 V8 engine and i want to register it in Caifornia?


Your 1979 Chevy Truck needs to be equipped with the following smog



1. A PCV valve/system (Positive Crank Ventilation). This is the pipe which

leads from the top of the valve cover to the intake manifold.


>2. An ACL (Air Cleaner Assembly). This is the air filter housing and the

duct that leads from the top of the exhaust manifold to the air cleaner



3. An AIS system (Air Injection System). This system is also known as the

Air Pump or Smog Pump.


4. An EGR system (Exhaust Gas Recirculation System). The EGR valve

recirculates exhaust gases to the intake manifold.


5. AN EVAP system (Early Evaporation System). This system includes emissions

components designed to introduce fuel vapors from the gas tank to the intake

manifold as opposed to the atmosphere.


6. A Catalytic Converter. Designed to reduce emissions after exhaust has

left the combustion chambers.
