CA inspections are tight assed bitc#es. you can fail with a simple visual (broken/cracked preheater hose) so no laying the PCV on the cover or even retarding the timing. Everything is checked to a master book that even shows idle speed and timing. My 'Federal" B2000 threw a few guys for a loop. It was a mechanic lein sale here so somehow it could retain its 49 state Fed emission profile and that year, the CA pickups had a smog pump while this one didn't. One guy said he couldnt test it. Another failed me because his CA book didnt have the Evap shutter vacuum line listed. One tested it and could not figure out how the 15 mph roller test was exceeding the RPM limit (what a dumb ***, just test the F'n thing in 2nd?) Nope, cant do that, the test says it must remain in L or first gear. Yeah, this is California we are talking about. Off to the referee to sign me off to authorize it to test in 2nd. Then he finds too much O2 in the exhaust,,,uh, what? Pinholes in the exhaust caused that and I definately had a few, with a rotted muffler. I think I got everything straightened out now on that turd. My only fear is high NOx level as the head as milled .030 to clean up some corrosion and I didnt install the recommended "spacer" that Mazda says to use if you mill the head. In a pinch Ill just run 2 head gaskets.
