Well after just a month of having my cosworth set up proply at msd has giving up already.noticed last night after going shopping with our lass overtaking a tracktor i noticed abit of steem coming through the bonnet.stoped and checked and water had spat out the header tank.not alot but obviously clear.looks like a headgasket to me.only done 400 mile.what i cant understand is that the car drives mint.no misfires or smoke or nothing.even still goes very well to.just paid all this money for nothing.am not a happy man.so does this sound like head gasket.
