Sounds like a plan! Let me know!

Hard to say about the cam when you shouldn't be turning one without turning the other. :signLOL:
Either way the head will need to come off as you will have bent valves. May not need a new head, it could be perfectly salvageable and just need cleaning/repairing and building up with new valves etc. You wont know until its off - although depending on price - a second hand one could be cheapest.
Whether or not the bottom end/oil pump is ok - who knows. Only way to is to inspect it - or sort the head/chain and take a chance. I'd want to find the missing bits of chain first though.
Personally I would remove the oil pump to check it, as if that's finished and was the cause of a loss of pressure, it could end up more cost effective sourcing another engine to drop in. For a £60 cost of bolts you would be able to inspect oil pump and bottom end, and know whether you are wasting more time and money

@Dan_FR The only thing is ive already dropped the sump, and put new oil in, so im ever so slightly hesitant to do it again, although I know I should really and probably will. I'm not even sure how the oil pump comes out. I know its built in to the balance shaft unit, but im not sure how that comes out. I think its pretty complicated because the oil pump is driven by chain of the crankshaft so removing it might prove difficult.
Yeah I'll take the head off and have a look at it and assess condition. There's one tiny bit of the chain missing, in the video I show one of the two bits.

Wow...I'd say the head is toast, the extent of the damage will only be exposed once it's off. Hopefully it's just valve damage and not anything else...good luck mate
