that's impossible.. he is the only one.. please dont tell me you went to AED.. haha
no I didnt.

About the only thing that can cause that is something floating around in your cylinder. Usually it's a piece of the piston. That doesn't just happen randomly. You need to get a bore scope in that cylinder ASAP and see what's going on in there.

Looked with a borescope. Can't see any damage.
Well then, now I'm lost. Because when I said scope it before, I was sure you were gonna post an update about a cracked piston.
Hmmm
When the head comes off, the combustion chamber will tell the tale.
I would think so.
I suppose what you could do is replace the two spark plugs (I would pull them all to inspect if you haven't already), then do a compression test on all eight cylinders. Hopefully you don't see a significant difference between the two cylinders where the spark plugs were damaged vs the other 6. (+/- 5%)
On my stock motor years ago I had a piece of piston break off--by the valve relief where distance to the first ringland was very thin. Anyway what was interesting about that is the piston looked fine, very minimal pitting, but the combustion chamber on the head was all jacked up.
Well thats good news. Are you going to do a compression check just to see?
Those look really good on there. Did you figure out anything on the motor?
