The bore appears to have escaped unscathed! There appears to be a very light visible mark travelling downwards, but it’s undetectible by a fingernail. My beemer has a much worse bore mark and never had an issue.
The other bank , oh hang on
I must admit I’m somewhat nervous about installing pistons. I also don’t know how to disconnect the broken piston from the con rod in order to fit the new one.
I’m guessing the gaps on the compression rings should be 180deg apart?
YouTube videos make it look easy but I’m not sure how the reality is
Parts wise -
New piston (no doubt)
New rings for all 3 (instead of just one?)
New exhaust valves x 6 on order
Inlet valves? Not ordered yet as I know they are usually ok?
Bearings where the con rods meet the crank?
Bolts for said bearings?
Head gasket, bolts and various gaskets
