Those of you that are telling me it is absolutely a failed AOS, are you surprised the car runs perfectly now? No smoke, stutter, warning lights, etc. It seem so me like the oil that got in the intake maybe just "sloshed" in there from the track driving, as the oil was at the max mark. It seem to me it was burned off on the drive home (highway for an hour) and it runs just fine now. Is this surprising?
Also, I just took the oil cap off while the engine was running. There was a bit of vacuum, but taking the cap off was far from difficult. The idle got a bit funky with the cap off. I quickly put it back on and the idle returned to normal. No suprise there.
Your thoughts? Inspect the AOS, probably find nothing and continue enjoying the car?
Oh, after looking through the previous owner's records I saw the AOS was replaced three years/18K miles ago.
