But that smoke in the LA video isn't coming from the exhaust, even though it looks from some angles that it is. It is pouring out of the engine bay.
And it isn't there for a couple of seconds either - just sayin'

Flogging a dead horse Crab!
The video is for indication as to what an oil-leak on a hot engine looks like.
I’ve tried to explain to you how this can happen on a healthy machine without a leak, but you choose to ignore that.
The smoke in the video brings back memories as it is very similar to what I experienced with the R22, and I repeat, it was only drops onto the hot exhaust that produced my cloud.
You, on the other hand haven’t answered my questions.
By the way, ASN has been edited I can see. Wonder why?!
