Will oil affect wideband readings
I had my intake off and noticed the previous shop failed to seal the intake correctly and gobs of oil was getting sucked into the lower portion of the intake runners. The car has been burning oil like crazy since a cam install and never burned a drop before it. 1000 miles = 1 - 1.5 quarts of oil. Resealed intake and the wideband is now giving a richer reading. Would the oil have been giving me a false or different reading?

I think the richer AFR is because it had a vacuum leak.
Now that the leak was fixed the wideband is showing the difference, that was to be expected.
Presence of oil doesn't change AFR readings, unless it's too much and it fouls the WB sensor
