Smog test today
 

Got the car inspected today and fortunately it passed no problem. I did notice on the 'hi-speed' idle test (2600RPM) that there was some faint white smoke puffing continually from the exhaust. Other than that, I've never noticed it before. Any guess as to what that might be?

I know white is supposed to be water vapor but that doesn't seem to make sense in this case.

My money is on coolant

Did you Idle for a while in line waiting to get up to be inspected?

I was thinking that too but my last oil analysis done about 1,000 miles ago showed no traces of antifreeze in the oil. Also, I have not had to replace any coolant over the last 15 months.

Not exactly sure, the technician might have had the car running for 5-10 minutes as he prepared the test machine. That would be my bet.

Thats what it sounds like.

Here in Fla. when they had the testing it was so touchy if you sat idleing for 15 minutes it would fail the test.

So do you think it is coolant? Why would the car emit white smoke at 2600 rpm?

Not Coolant but Condensation from the exhaust.

Oh, that's way better than coolant! Nothing to worry about I guess! Thanks.
