Few Questions about headgasket leak

[emc4raz]

If my car is drinking more than a litre of water in 30 miles would it drive at 100mph with no over heating, smoke etc, i drove it and did see a line of water under the car.

My car also has water coming out between the doser and rocker cover, i missed out the gasket (which is ordered), which is probably moisture would this be the cause the for depollution light coming on as its sending the wrong pressures etc to the electro vales located on the bulk head

Its pressurising the coolant system big time to throw water out like that.

I know, my 205 did this when I first got it (I was aware of this) , I did not drive it until I fixed it. Towed it away from the sellers house.

Does need sorting as you are going to have head warpage issues if not already.
