I am looking at buying a used truck, a 2001 Chevy 1 Ton Crew Cab Dually w/ the 8.1 Liter Engine and Allison Tranny. The truck I am looking at has California Emissions, and since I live in Michigan, I don’t have a clue as to what that really means other than I guess it is a little cleaner. Are there any issues that we don’t think about here ie extra Maintenance due to what I guess must be extra smog control equipment? I figured I would run it past you guys here as I don’t read any car forums and figure someone here will have a comment or two.

THANKS!

Eric

I live in Cal but am not sure what differant equipement our cars have, I am sure it is nothing major that you have to worry about affecting performance and such. I know our gas is formulated differantly and I thing most smog is affected that way. If I were you I would just leave it alone.

Call a Chevy service department and ask if it is a "49 state" truck or a "50 state" truck.

If it is a 49 state truck then you can count on it having a different black box, different cams, perhaps a different intake, smaller valves, lower compression, smaller injectors, revised timing, smaller diameter exhaust pipes

If you were buying a motorcycle I would tell you to walk away from it.

I drive a 1989 Toyota 4WD that has the "California package" and AFAIK it's just an air pump.

This year I had to have my truck emmission tested and it once again passed with FLYING COLORS. Surprisingly, it flunked because of the GAS CAP.

This passes so easily here in AZ that I've got a LONG WAY TO GO before it'll flunk. So I guess I'm saying that the CA package MUST make them run cleaner or the emmissions are cleaner.

My results were:
HYDROCARBONS: My truck: 0.62 APPLICABLE STANDARD: 3.00
CARBON MONOXIDE My truck: 8.65 APPLICABLE STANDARD: 25.00
OXIDES OF NITROGEN: My truck: 0.81 APPLICABLE STANDARD: 4.50


And my truck has 193K miles on it.
