toying with buying a rangie l322 but it needs new engine (I haven't heard it running yet but apparently it's knocking like hell) , whats the cost likely to be for a replacement engine and where do I look to buy the engine from.
Unless it's really cheap and (except for the engine) in very good state, and you can do the work yourself, I wouldn't bother with it - it could end up costing you more than a decent one.
