In my original comment with the video I literally said I did all that... I took the engine covers off and inspected the entire area with a flashlight. I saw absolutely nothing that could have caused all that smoke. And then I ran the engine again and the smoke didn't return. No 'epiphany', unfortunately.what you have to do is, take the covers off and look CLOSELY with a light where the smoke is coming from ?
epiphany will strike, you'll see it quickly. it's not something that can be diagnosed with a video like that, you need to see down into the engine,
at the actual lines, components, wiring as to which one it is.
Others in this thread have mentioned the fuel pressure regulator as a possible culprit, as the engine is running rich with a strong smell of gas in the exhaust. Not sure if that's it, because the regulator is less than a year old and was replaced with an OEM unit. No smell of gas in engine bay itself.
I don't have a scanner for this car, so it'll be going out to my mechanic on Monday.
