First of all, it's worth pointing out that this engine was re-manufactured by Ivor Searle (very well renowned company) in 2009 and has since apparently covered around 70k, and I think it's been serviced well as there was no baked on black in the sump or on the oil pump... It's also probably worth noting that it had a catastrophic turbo failure fairly recently
So I've just stripped this engine down an there's two main things I've noticed... On rod number one (closest to the cam belt), the big end shells was rotated 90° and the locating notch taken off:
I wouldn't say it been like this too long as there was no obvious scoring to the crank.
The next thing I noticed was the oil pump chain tensioner, here's a picture of it next to one twice as old from an AGU engine:
As you can see it looks like there's been a fair bit of heat there as it looks like the tensioner has started to bubble a little where as the AGU one (although rather black) looks fine.
There were also a few random scratches on some of the main bearing shells straight down the middle:
As far as I'm aware one of a couple of things has happened... Either the turbo failed and sent bits of turbo bearing into the sump and through the engine causing the damage or, the oil has been contaminated causing all of this and that would probably explain the chain tensioner better. My other thought for that was a possible over rev, but sill that wouldn't quite add up
I'd be interested to get other people's opinions, either way I'm not too fussed as I only really needed it for the block which still looks good and it came with over size pistons, which is nice!
