So, as the Queen of Hearts would say, off with her head !
My first time, and it hasn't been too difficult, lots of 10mm screws holding brackets etc in place, but I found them all. The job was probably made considerably easier because the exhaust manifold and turbo have just been refitted with new nuts so no rust to contend with
First of all here's the block / pistons - minimal cleaning done at this stage, just a wipe to get rid of coolant
and then the head. You can see a progression of oil contamination going from cylinder 1 to cylinder 4. It doesn't look like there is any contact or bent valves though, so that's good
Now at this stage all I can do is compare the amount of rock on the piston in the cylinder. Most tellingly, there is virtually no movement on number 1, while on number 4 I reckon there's about 1mm of rock in total. That's a smoking gun, but it's time to call it a day, so nothing more for now. Next activity will be dropping the sump (for the 4th time in my ownership) so I can release the pistons and rods upwards
I didn't have an elastic band so used a tie wrap to hold the chain together. I need to discover how to make sure the chain hasn't moved on the intermediate shaft, but that's for another day too
