Engine rebuild?

[nedrobmas]

Got a borescope camera to find dirt but found this, how bad is this and why is it so clean?

One picture straight down the other side view of cylinder walls.

Yikes…man, that does NOT look good 😳

How does the engine run? How much oil consumption?

Ouch. Unless you poured some acetone down there, I would say the injector got stuck open, flooded the cylinder and washed all the oil away.

Unless the scope and camera are making things look worse than they are. That looks like a new block conversation/ sleeve job.

Since it probably diluted the oil, check all the other journals when you are tearing it down.

Trade that in now

Engine runs with a lot of smoke and burning oil, tailpipe passenger side wet oil, misfire cylinder #3 (pictures above).

Ima try somethin since I need a new engine and upload the results.

Cylinders #2 and #3 exhaust port, I dont know what causes that, any ideas?

I’d guess piston pulling in a lot of oil during intake stroke. Normally I’d say from valve or turbo seals, but in your case I’d say also a ton from the PCV system due to blow by, and maybe even sucking up vapor from the crankcase on the intake stroke due to lack of ring seal

However, if it was from the turbo seal or PCV system I’d expect cylinder 2 to look a lot more like cylinder 3, soooo… 🤔

Not to be a downer, but that looks heavily gouged, not scored. Apart from sleeving that, I don't see a way out.

That much oil is not normal.

Also consider, if you are actively gouging the cylinder walls. That metal is going somewhere. If you keep running it like this, that metal may end up on somewhere that you can't repaired/cheap to replace. So You may total your head/crank/other pistons.

Facing towards engine its the 5(pictures above) and 1 o clock position. The plan is to find what happened and how while I look for $$$ for engine swap.
