Hi all, quick update:
The engine strip-down is going well — slow, but making steady progress. I'm taking lots of notes and photos as I go. Just wanted to share the current state of it. Leaving it here 😄

Just for comparison this was my oil separator after 124k and before cleaning.
Mine might have missed one oil change early in its life as I have a gap in the records.
Has had 5k oil changes in recent times.
Looks quite different from yours!

Hi,
Quick update on the engine rebuild. I completed the engine disassembly today and removed the crankshaft to inspect the condition of the main bearings.

What I found is a bit puzzling. The conrod bearings are severely worn, as shown in the attached photos. Strangely, the front main bearing had been pushed out of place and was damaged. The surprising part is that the crankshaft journals are undamaged—almost a miracle. I measured the journals and they are within spec.

This raises the question: why was the front main bearing pushed out of place? Could it be due to a bent crankshaft?

I also discovered two broken piston oil jets and crushed tubes in the oil pan—another mystery.

Let’s continue the checks and hope the engine can still be repaired.
