This is what coolant leaking into the combustion chamber looks like exhaust wise on cold start. Coolant leaks into the chamber during the cool down cycle and is burnt on start up. Anyway it shows the colour of the exhaust discharge and the concentration when it's chronic. You can also hear it misfiring for a while as well. The image is a borescope image of the same engine type Focus RS 2.3Litre turbo and you can see the beginning of the leakage at the bore bridge location. You can see the cylinder head and cylinder wall and the head gasket clamped between them both. Not chronic at this point but "on the way". Second image from my engine and nil leaks evident.

these kind of videos give you that sinking feeling. Fortunately the mk 2 RS i had didnt suffer as badly as the mk3 did with issues like this. The 4 pot wasnt as strong as the plasma coated bore volvo 5 pot in the mk 2. I had a heart attack on cold start up the other day after coating the inside of my exhaust with foam during a touch up wash of my supra. Was blowing autoglym polar blast white smoke for 20minutes.
