I popped into my dads work to say hello today, and he showed me a piston he extracted from a ford Ka. It was fubar'd, melted through and a right old mess. He's replaced the part and cleaned up the engine, but he couldnt explain why that piston had melted.

So here I am, opening up a discussion for reasons why a piston may melt in a Ford Ka engine. The only thing I know as to why a piston can melt through is a really hot burn from running lean, but it wasnt the case here

sooooo

what could have happened? I'm really interested in this sort of stuff, i find that when you discuss engine faliure, you end up learning alot

I'm gonna see if i can get hold of the piston as a paper-weight
