I would imagine that if you've got the engine stripped and identified bent conrods, at this stage it would be easier to just replace them. The crank will be ok and its not uncommon for the rods to bend when water gets in. By the time you've bought and replaced with a secondhand unit etc it would be cheaper to throw in a new set of rods.

Hi Sam, - if you go down the road of a seconhand unit you 'may' need things like ECU which 'can' be set to the engine.

I have heard people say that Euro Car Parts are reasonable on parts but I expect someone on here may come up with an alternative source.

You could go down the avenue of asking scrappies if they've got an engine with a knackered top end or broken belt. At least the rods will be ok to transplant. You might get a scrap engine for a song and provided you've willing to strip that too you could save a packet.

Hope this helps
