so my 97 z24 176K seems to have developed a leaky HG. i've been going through coolant at about a gallon a week. seems to running fine, no cel's or anything. anyway i'm thinking about doing a head gasket replacement myself. i'm a pretty decent mechanic so far so i'm not too worried about it, but is this a pretty quick process? i'll be attempting with the motor in the car.

anyway any help, tips, hints would be awesome......... thanks
