hey peeps, right ive had a prob with my car pressurising the header tank for ages now, well since ive had the car! ive never got to the bottom of it, well today i took the thermostat out and had a look.....and found that some one has drilled two holes in it?? well i put a new one in and now it boils up straight away, all the pipes are rock solid.. so i got pissed off and took the head off. i think the head gasket has gone on one cylinder, also i noticed that bits of my old water pump were wedged in the water ways in the gasket!! so i thought well ill just change the gasket and skim the head ,
