Right, we've got a problem.
Driving to my mates, M4 came to a standstill so pulled off at the junction before the traffic slowed down. Went onto A roads and at traffic lights, saw a bit of steam again. Pulled into sainsbury car park, opened the bonnet, seemed ok, looked at the back of the engine and saw water start to drip onto the exhaust. F###. What i noticed was that this time and the time i stopped in the morning, the car was higher at the front (due to the ground level being raised at the edge of the car park at each spot i was in) - hope that makes sense, in other words, imagine the car was jacked up by half a foot form the front. It seemed that this must have been pushing water to the back of the block? Hope that made sense. I also noticed the water level in the water coolant bottle was quite a bit low in the morning. I have noticed that i've had to fill it up quite a bit before. Maybe it has always been leaking a bit but just not enough to be this noticable and now it is noticable. I'll post some pics up, didn't get any when i got home as by then, as the roads were flat, no water dripped down, so i only have pics of the area affected. Will try in the morning to jack it up, start the car and replicate the issue, maybe post a video.
The water seemed to be coming from the edge between the valve cover and where it meets the engine block. Silly question and i'm a bit shaken (got work tomorrow, no second car etc.) so not thinking too straight and a bit rushed, but how could water be leaking from that part, it would be oil wouldn't it? I'm thinking head gasket at this stage? Would that leak in such an area? Couldn't could it, as the gasket sits under the exhaust, whereas in this case the water is falling onto the exhaust. It was dark so a bit hard to see, used the light on my phone to see, and it seemed to be dripping from there. What do i do 
Near that stupid air pipe that plumbs into the exhaust, follow that down and back, there's the header bolt into the block and a flat part ontop of the exhaust - that flat part is where the water is falling onto. Don't know if it's coincidence but note the moisture on the bottom of the tubes above, and also on the side of the wiring plastic wrap thing.
See on the corner, the block appears to be in black paint, then there is like rust on the middle, thats where the water appears to be running down and then onto the exhaust.
