You can try and remove the valve cover and see if you can see the chain loose. Thats what I would do first I have seen the valve guides even get split from the pistons hitting the valves. Lets see what we find with removing the valve cover. Worse case senerio you need a head and timming chain set. Let me know what you find and we will go from there.

Ok found time to remove valve cover and timing chain cover, I have noticed the timing marks do not line up (sprocket/chain), also when I manually cranked the the shaft the chain would give slack then it would tighten up? I havent touched any of the tensioners, I haulted for now before I pull the head (i dont want to miss any important clues)

There is only one tenisor which is screwed into the engine on the left side of the side of the timing cover. The chain shouldnt slack while turning it over. So are you saying the colored links on the timing chain arent lining up with the cam sprockets?If so they wont till the engine rotates around like 33 revolutions. Keep turning it around most likely one of the colored links will line up and the other one will not. We need to do that so we can see how many teeth the chain jumped. If its not too many we can put a new timing chain kit in it.

I was able to remove the head, all cylinders look ok, except #1 it appears to have been hitting the exhaust valve, and there was a piece of molten medal just sitting there? Pic supplied

So does that melted chunk pop off?Also is the valve guide split on the bent valve?Sometimes when the valves get hit they split the valve guides.
