Can someone help my newbie eyes please? I believe after watching some videos that I have the signs of a spun bearing. Video of me checking the first cylinder that was knocking is attached: https://youtu.be/vqKG-SwZ9Q4
So as I began to tear into the engine....
1) Is this carbon build up unusual that's in the exhaust ports?
2) I notice rust on the valve springs - unusual? I feel like I see metal shavings and water or some type of sludge mixed in with the oil. When I drained coolant it was green as Spring grass...?
3) 1st cylinder (my failing cylinder) is on the left. I don't know what to look for on these cylinders but the #1 is black...#2 and #3 are just grayed out and not nearly as built up with carbon.
Thanks for looking!
