Re: Anybody CA smog licensed???
If the engine originally was equipped with OBD II, then it
MUST be used.
As far as Evap setting codes on OBD II, I don't know.
It starts with a visual inspection. The inspector looks in
the book to see how it was originally equipped, then visually
looks to see that ALL components are there and hooked up
The evap system: Technically all the lines should
be traced under the car to make sure they go where they are
supposed to, but they usually are hard to see so it's usually
skipped by the tech. The referee may not, so keep them hooked
Some components he has to actually test, like EGR with a
vacuum pump for a stumble test, and the gas cap for leaks
with a pressure device.
Then he pulls codes if it's OBD II.
After that, even if it's failed some of those tests, he's
required to run it for actual emissions.
Then the actual emissions test is done. In some areas of
California they have to use a dyno, and check for NOx emissions.
Some areas don't use that - yet. Whether dyno tested or not
is not determined by where it's tested, but by where it's
registered. So coming out here to the desert where we don't
need to use dyno's doesn't help.
Sooooo - esentially ALL devices and controls that were originally
fitted on the body, like evap, cat, etc. are needed, AND ALL
controls and devices originally on the engine are needed
The end result is the emissions standards the original
engine had to conform to.
And - the engine must be the SAME year or NEWER than the body.
You can't put a '75 engine in a '95, but you can put a '95
in a '75.
Just getting that ability approved nearly took an act of God.
The way it was if ANYTHING was changed, """NO!"""
Emissions devices aren't really there to control emissions
much in normal operation, they are mainly there to stop the
emissions when the engine misfires or runs poorly. Many
folks don't maintain their vehicles very well. So essentially
most of the devices are about like running along behind the
horse with a shovel - just in case!
If you took off all of the emissions devices on a properly
tuned engine in good condition you'd find that it's close to
the standards anyway. But keeping them that way is difficult,
like balancing on a needle.
The smog laws really are there to protect our health, the
trouble is they are written by politicians that have no idea
what they are passing.
AND - their motivation is from the car makers - they can't
sell new cars if everyone has old ones, so the car maker's
bribes to the politicians (sometimes called contributions,
sometimes deposits in their Swiss bank accounts, sometimes
just skiing vacations, cruises, cars, and --??) are based on
new car sales. The politicians job is to get older cars off
the streets fast so they get more "under the table."
