Title: 1987 A.I.R. emissions system
Post by: hef1125 on March 08, 2011, 12:54:54 pm

I recently purchased a 1987 Chevy V30, 350ci TBI pickup.  The previous owner lived in a county that does not require emissions testing so most of the A.I.R. components are missing.  In order for me to register it in Phoenix, it has to pass emissions. Besides the air pump what are the other components of the AIR system?  Where would I find a diagram of the system?  Any help would be very appreciated.

I would go to an emissions station and see what equipment is needed. My buddy got an 87 through in Chandler with an evap can and cats.

Is it just a tailpipe test?

Thanks for the welcome slammed79.

VileZambonie - I think its just a tail pipe test.  Here's what the website says:

IM 147: This is the enhanced test used for most 1981 through 1995 gasoline-powered vehicles in the metro Phoenix inspection program. In this test, the vehicle is driven on rollers (called a dynamometer) at varying speeds to simulate urban driving. The exhaust is continuously measured and the results are shown in grams per mile.

Tampering: In addition to one of the above tests, a vehicle may undergo a visual inspection to determine the presence of certain emission control components as installed by the manufacturer. Inspection includes catalytic converter, operational air pump, positive crankcase ventilation system and evaporative control system. These inspections coupled with the evaporative system integrity (pressure) test constitute the tampering inspection.

Not just a tailpipe test.
