Whats involved in changing head gasket



  Mk2 Golf GTI


right im pissed off with my car losing water so im changing the water pump and cam belt. as ive got to take the belt off anyway i was thinking of changing the head gasket because there seems to be a suspicious line of water running between the head and the block. is this a straight forward procedure and what exactly is involved. i dont know if the head gasket has failed but it seems strange the water is lying in this place. There is no bubbling in the header tank and no mayonnaise in the rocker cover so im guessing there is no water in the cylinders.

Thanks a lot people
 


yeah its a straight forward procedure if youre handy with the spanners.

u need to take off the cambelt and alternator belt, remove the manifolds (if you want to skim the head) otherwise just split the exhaust manifold/downpipe, wiring loom, pipes etc, then take the rocker cover off, remove the head bolts, then pull the head off the block.

the head may need skimming to ensure its flat, the mating surfaces of the head n block will need to be cleaned up with very fine grade wet n dry paper, then rebuilt using a new head gasket and head bolts.

buy a haynes manual if your gonna do this as its got step by step guides in for this kind of thing, aswell as the torque settings for the head bolts. A Haynes will come in handy for setting the cam belt too

cheers for that. i actually removed the belt last week to re-seal the water pump but its still leaking. i think it is still the water pump as people have told me that there is a gland that perishes. i wanted to change the head gasket as well seeing as the belt has to come off anyway

cheers
