Passed smog by changing oil
If any of you are going for a smog check try changing you engine oil. My 22re was missing and it still passed because there weren't, as I saw on a pretest, excesss HC's coming from the oil/crankcase. Adjusted the tight valves and the missing went away.

Yep, overtime oil is contaminated by hydrocarbons which the PCV valve picks up, dumps it into the intake manifold, gets burned in the combustion chamber, and out the exhaust to the sniffer.
