No, I just checked both spots. I put a white t-shirt over the pipes when I started it this morning. There was nothing on the shirt when I took removed it. Don't know exactly what that means?
Well, the white t-shirt wasn't entirely the right tool, but if it was black it would have told you you're running rich.
Don't think you're investigating black smoke right now.
The t-shirt is too porous/wrong color to catch anything else. That's why I suggested cardboard. Like maybe the brown corrugated kind. You might have to have someone hold it for you while the car is started, or tape it to something to hold it.
And if the white smoke only lasts a few seconds, you'll need to be moving quick to see if anything splattered on it like water vapor etc. The hot exhaust gas will dry it if it gets wet very quickly.
Might best be a 2 man job.
The mention of smell was also a good one. Burning oil and water vapors ain't the same when it comes to a sniff test.
Once again, might need someone standing back there when the car is started to catch a quickie whiff.
