Interesting borescope session from cylinder #4 https://vimeo.com/80341238 As you can see it contains white "fluffy" stuff which I suspect is the main gasket. Note the time after 40 seconds when I go through the stuff, it is quite soft. Plugs looked fine, brown colored, all cylinders look OK too in my opinion, except that gasket stuff. Other cylinders looked fine, but #6 had also small amount of the same stuff that cylinder #4 had. I cleaned my throttle body to figure out small oil leak. After I was done I decided to try it out and noticed that my idle is now better. Engine worked fine for 15 minutes, after that I revved it a bit to 3000rpm for a couple of times. Finally when the engine was warm I pushed the pedal 100% down for a fraction on second gaining almost 4000rpm, immediately after that I got rough idle and noticed that some cylinder(s) are not firing. Loss of power / throttle was noticeable too. After 10 seconds I got knocking (around 5 per second) + CEL, then after 10 seconds CEL flashing and decided to stop the engine. Durametric shows cyl 4 misfire. After that I took coils and plugs away and grabbed my borescope. I was not happy what I discovered from cyl #4 :-( Any opinions is the engine done or are there any viable options to try out? 911 Carrera 4, cabrio, 3.6L, 2004 Updated picture link here: https://www.dropbox.com/sh/rlzlul4q7n58ui6/-tP8T4hMey/Paper-inside-engine
