The text of the bill states "This bill would delete the above partial smog check exemption for collector motor vehicles from existing law. Instead, the bill would fully exempt a collector motor vehicle from the smog check requirement if the vehicle is at least 35 model years old and proof is submitted that the motor vehicle is insured as a collector motor vehicle, as specified."dr bob wrote: Sat Mar 08, 2025 5:56 pm
There are some popular beliefs around the Cali standards, like one that the regs tighten every year for older cars. They don't. The tailpipe and equipment standards for any specific U.S. market car are the same now as they were the year the car was first certified for sale. The proposed legislation does nothing to relax those same standards, it only appears to offer a little relief on the testing. Got a modified car? This won't help you much. Got a tired and non-compliant car? Not much relief there at all. They only test the tailpipe and the gas cap too.

So, if one could meet the "collector car" insurance requirements per the law, it seems there would be no more smog checks, so run what ya brung! But again, I don't have much faith in this passing given the current climate of CA politics, even though the entire fleet of 35+ year-old cars in CA have a minimal impact on the overall environment. It's all about optics . . . .
I 100% agree about periodic 5-gas analyzer checks of older vehicles, it paints a good picture of what is going on inside the combustion chamber. I compare OBD-I and older customer cars with the O2 sensor connected and disconnected to get an idea of the general state of tune (after checking for vacuum leaks), and generally tune them to be just rich of stoichiometric at idle, they seem to be happier there. Fewer parts per million of HC and higher CO2 percentage=happier engine.
Five-gas analyzer is also great for diagnosing crank but no-start or hard starting conditions, can use the hydrocarbon (HC, or unburnt fuel) reading to great effect.
