My engine spits out a tad bit of smoke (oil) when revved (engine cold) but doesn't seem to be a problem when warmed up and driven (probably a bad valve seal, compression is great). Should I be worried when going up for emissions testing (Arizona)? How big of an effect does burning oil have on the test?

 

it shouldnt be a problem. just make sure its warm. ha

 

I'd be more concerned with the burning oil fouling out your O2 sensor. Fouled O2 sensor = increased emissions. I'll let you figure things out from there.

 

In Georgia (have no clue in AZ) OBD2 cars (96-up) do not have to pass a "sniffer" test where the reader in inserted into the exhaust to actually read emissions coming from the engine.

Here all OBD2 cars have to pass is a scan tool hook-up, which only check for check engine codes stored and/or pending. In other words no check engine light = vehicle will pass emissions in Georgia.

As far as oil smoke affecting emissions, believe it or not it does NOT. There is an emissions station located right next to my shop, and cars bellowing blue/gray smoke even at idle still pass the exhaust pipe reading emissions test all the time, yet cars NOT smoking fail on NoPPM for EGR bullshit, or cat convertor issues, etc.

Black smoke, or fuel smoke under load, will certainly contribute to faling emissions as it indicates a rich condition.

This of course again only apllies to a vehicle that has to pass the exhaust "sniffer" test, not OBD2 scan-only tests.

 

Yeah, I'm pretty sure we have the OBDII ECU scan only test here too, but I'm afraid that if they see any smoke at all that they'll hook up the sniffer.

No they shouldn't. There won't even be a tesing procedure to run an OBD2 car on the dyno, or at least in GA there isn't. All they care about is if the check engine light is on - that's it.

It's the same in NY. That can prove a bit harder than it sounds though, especially if you're running an OBD-I system in your OBD-II car.

Impossible to run any tuning equipment (as it's all OBD-I) in a '96+ car, here, as it won't be readable by an OBD-II port-scan.

True.

I'm assuming he's got an OBD2 99-00 Civic Si though since he hasn't really offered up any extra info such as jumper harness and tuned P28, etc. etc.

 

Bone stock EM1.

 

besides at the revs the test is carried out at the smoke shouldnt make a difference

 

Its the same in NJ. Just to cofirm. my car is a 98 and they only hooked it up to the Scan tool for Codes. But with my first car. 86 escort, they put it on the dyno and test emissions Under load.

 

Shouldn't be a problem. Heres a hint that most people don't know though. Often a car that will not pass emissions test, will pass after changing the oil.
