This channel is a joy to watch and learn from. Love it!

That's great to see. I haven't stripped an R90 engine for 36 years 😬
Coincidentally, it had a gudgeon pin circlip that had jumped and marked the bore, although it was only in for weeping bases.

Good thing is that bore is completely untouched but someone was not paying attention last time it was apart. They were also able to flip head gasket which is directional so pushrods were rubbing against gasket. Fun fun. Thanks for watching!

Wow you were really lucky to find that circlip in time. Any damage to the cylinder? Hope not. Thanks for sharing, Happy new year😊

[@airheadbarn]

Luckily no damage to cylinder. Thanks for watching and happy New year!
