Well I just pulled off No. 2 and No 3 conrods. At first glance it is not as bad as I expected. Though I might not be trained enough to make that call. Here is No. 3 crank and conrod...







Pretty obvious scoring mark towards the centre there on the bearings that can be felt with the hand. But what caused it? Debris getting trapped during installation? Long periods without oil or filter changes?

The top half bearing also appears to have been squished out from the sides. The bottom one has a little bit, but it appears to have followed on from the top half.

Here is the inside of No. 2 and 3 rods & bearings, respectively. I wiped them clean before taking photos. Smelled very burnt and a bit of carbon came off... Probably goes back to how the oil was about 500ml's of black watery crap when we got it...





And a closer look at the top half of No. 3 bearing... squished. Both halves had the locating tabs broken
