I have to take the old emissions test, this will be the second time. My rings are worn and as such, I burn a bit of oil. Short of doing a rebuild of the whole engine to fix that problem, my question is this:
Is it better to take an emissions test with the engine cold or warmed up?

I was told that part of the purpose of the catalytic converter is to burn off the excess oil that seeps through the rings and gets into the exhaust. So it would make sense to have it nice and hot, am I right? Or am I completely way off?

Also, the mechanic stated/hinted (off the record, of course) that he would be curious to know what the results would be if I went in with the PCV valve disconnected. Would that make a difference? Is it legal? The emissions guys never check under the hood...
