Finally got around to tearing the motor apart. Looks like Cylinder one completely shattered and is in the oil pan. Cylinder 2 looks to be melted/shattered. Head is completely destroyed
Dang! Looks like the piston ring was the only thing left holding that piston together. What the heck! There are so many sinister and creative ways that these engines fail.

That looks like an extreme example of broken ringlands.
Surely a catch can would fix it?
Plus making the vents all bigger..........it always works.
It even stops the dipstick from blowing out.
Check the sparkplugs.........there's oil on the threads.
Tells you you've broken the ringlands.

I don't think so as the belt was in good shape when we pulled the head off. Maybe jumped timing??

Piston and rod for cylinder 1 are in the oil pan, I'll get around to remove the oil pan this weekend.

Didn't have any spark plugs left . I just got my hands on a STM 3port VTA OCC just incase

Just ongoing and excessive detonation.
Once they get a bit of blowby, the oil reduces the octane rating and it detonates more and more and more.
If you've got an aftermarket ECU, the knock detection won't work.
, but not sure why it wasn't spinning before. Still going to send it out to CRBD for an inspection/rebuild.
