1996 Mitsubishi Eclipse head gasket

You need to spend $12 and buy a repair manual. Replacing the head gasket is easy but you have to remove the over head cam which means all of the timing marks have to be lined up and you have to replace the rocker arms exactly as you found them and you have to torque everything just right.

The book will explain that and how to determine iof your head is warped or needs machining. Its a lot to go into.
