Well progress has halted.. Due to some idiot not tightening an idler pully enough the cam belt slipped and the zetec had a little accident [B)][8~2]
I've got the head off, doesn't look too bad. Looks like the exhaust valves made contact with the pistons, but the inlet valves and the pistons themselves look ok. Fingers crossed.
Annoying thing is I heard a rattle and was looking for the cause, the rattle was the pulley coming loose and it let go while I was investigating. I thought the noise was the alternator, as I'd just changed it.. Luckily it meant the contact happened at low rpm.
Ah well, will order up the new parts this week and hopefully be going again in a few weeks!
