My truck passed smog test in Yuba county where I bought it but will not pass in Contra Costa County. Are there different regulations?
You need to ask each place individually where the truck was tested..usually its the same in each part of the state..as my experience has been .. compare the differences if any,,

SOURCE: failed smog test
trade it in on the scrappage scheme against a new one .or take it to an authorised garage for emmisions ,cant just point a finger at a certain component and say change that .Sorry but without the right equipment i would only be making educated guesses .What condition is the air filter in ---did you clean it before you went for the test

No, the water pump leak would not cause it to fail the smog test. The only way that could have any bearing on the test results, would be if you lost a lot of coolant, and the car was overheating, then maybe it would have something to do with failing. What were the results (specific #;s and exactly what failed?) Is the check engine light on?
SOURCE: PCV valve failed visual inspection during smog
remove the hose to the PCV and It simply pulls out and a new one is pushed in and hose is inserted back on. It's kind of like a cork. I can not believe they check for visual inspection. Here in SC, we don't have inspections. But anyways, GOOD LUCK

Could be lots of things.
It could have a leaky injector that is dripping all the time.
You can pull the injectors while still on the fuel lines, to see.
You could have bad compression and burning oil.
You need to do a compression test to tell.
You could have a bad plug or wire.
They are cheap to so just change them.
The fuel injection system could be off.
Check the temp sensor, air mass sensor, O2 sensor, with an ohmmeter.
Don't remember the values, but bad ones usually go 0 or infinite.
Vehicle smog test failed Due to NO MIL/check engine light?
