Ok so I don't want to condemn it just yet, this morning I've been outside and flushed the cooling system with some water and washing up liquid lol. Strangely the water that was flowing out was only a tiny bit dirty like you would expect. No oil or sludge from the bottom the rad or the head? I've left it in there to sit for a few hours and I will flush it some more later on. I should also be picking up a compression tester so i can check that too
