hi, i drove my 95 sti to work the other day and when i got there i noticed water under the car, the header tank had split, i have now fitted another one but when i fill it up and run it on tick over, it builds up a massive amount of pressure and spits all the water back out, is there a way to fill it up to get rid of the air lock, or is there a problem with it, cheers phil.

i have just done a compression test, and the left side is fine at 12, but the right side are both at 8, so the head gasket has gone but i thought there would be less pressure, also the water stopped spitting out with the spark plugs out, thanks for all the help on both threads, phil.

Sounds like head gasket mate.
