Flashing CEL + Blue Smoke?

It can be also blown head gasket due to overheat
Do not drive it like this

A flashing CEL means immediate shutdown, immediate flatbed, immediate code read and immediate access to a mechanic extremely experienced in the diagnostics necessary to determine the fault. Solid CELs can limp home usually, blinking ones indicate a major risk failure detected.

Good luck.

There is a lot of mention of immediate shut down, which I agree with, but it did not happen. Because it was not shutdown, we know that the flashing CEL did not stay illuminated. If there was an issue that was going to cause the engine to self destruct in seconds/minutes, would the light not have continued to flash? A misfire will cause a flashing CEL. The problem clearly seems intermittent. So the solution is to have a proper durametric read of DTC history and go from there. Or as an alternative he could continue to hang out here and be lectured about something he can not change...

Sounds the engine ingested some oil thru the AOS, maybe during a hard left turn? Pull the sparkplugs & inspect for oil fouling starting with #2 the middle cylinder on passenger side.

Thanks for the replies guys.

Yes, I definitely know the dangers of driving with a flashing check engine light. Unfortunately, I had cars coming up behind me, and had to use some power to get to the right side of the track, and out of their way.

Like, I mentioned the CEL disappeared soon after, so I figured it was safe enough to drive home. I would not have driven home if the CEL was still flashing away.

Sounds like I need to get my hands on the Durametric tool and see what codes its thrown. I also should probably inspect/replace the AOS.

I will also pull the plugs and check to make sure they're not fouled...
