Arrghhh! I've got a coolant leak too!!!
I've stripped everything off the front of the engine and it looks like it was leaking where the water pump seals against the block.
It was a new waterpump and gasket, but the gasket was a very thin metal one and the sealing face on the block is slightly corroded.
I bolted it back on again with a load of sealant this time so hopefully should be ok now!
Also looks like my oil leak is coming from leaky cam seals. I'd already replaced both of the seals... but it looks like the cams have a groove worn in them from the original seals, so not sure they've ever going to seal properly again
I had a spare pair of seals and have replaced them again, but I'm not very confident...
