High boost at part throttle-inducing knock

[TopherSho]

Call me crazy but at 2:08-2:10 there looks to be something protruding above the cylinder along the cylinder wall.  as for the barb .. i cant QUITE tell but it "glints" differently.

not to hit the panic button.  but to be frank.  this looks like debris in the cylinder,  that barb and hunk of whatever at 2:08 makes me think something made it through the turbine at a high rate of speed. but that's my tinfoil crack pot theory.

I'd pull the heads at this point. we can see physical things in the cylinders that we should not see.

this is a used rig?  any chance this was ran on pure e85?  there was a lot of oxidation in the cylinders as well.

My gut reaction is those are turbine bits..

I bought it new in '16. It has 30,000. No e85.

weird.. I vote for pulling the heads.

Hard to call it an artifact, it is so well defined.  Maybe a shaving that got left in there?  Hopefully it has magnetic properties, you might be able to pull it out the spark plug hole without pulling the head.

BTW, no video.  Seems to b just an image, nothing to play?

Ok i see the link now, updated it to give it visibility.

Hope the dealership works with you once you produce the evidence.

It almost looks like a reflection from the cylinder wall or top of piston.

glock has a super hubble borescope you can borrow.  LOL!

I would hook it and see if you can pull on it.

My question is why is it still in the cylinder and not blasted out of there ?

One thing for sure is "Thats No Moon"

Lets see if it is real or a reflection!

FWIW found a stowaway while removing the Front bumper and guess anything is possible. Z  :yikes:
