depends on the price! cant be worth that much with the history can it? Gotta be worth trying if you can get it dirt cheap?
depends if the pistons have been damaged by valves hitting them I'd have thought. If you could get it dirt cheap & it's just a case of replacing some valves & timing chains then it might be worth it. Don't bid on it without going to see it first though.
blimey, you gotta wonder how badly looked after the engine was for the chain to break! jumping teeth maybe but breaking! Are they duplex or single chains?
