All Small Six Endoscope pics

[Kritas]

I bought a cheap endoscope to be able to peek into areas that are hard or impossible to see on my car. I took a couple of pics of the tops of the pistons in cylinders 1 and 3 this morning. Things look pretty oily to me, and the new plugs look sooty and grimy. Granted, I've been working on the car and there have been some issues as it's not seen the road yet and is far from dialed in.

What do you see here?

Looks like there is some carbon build up starting on the Piston Tops. You could try doing the old time De-Carbon treatment.

DE?

"De-Carbon or to decarbon" sorry the two should have been connected together. https://www.cardekho.com/advisory-stories/maintenance/engine-decarbonization-demystified.htm

Old timers I learned this from would get the engine warmed up good then raise up the Idle RPM enough so it would keep running as you dribble a Glass Coke Bottle or 2 of Water down the Carb's Throat. The steam would loosen up the carbon sending it out the exhaust.

Gotcha. I've used stuff like Seafoam for that. In through the carb or manifold port.
