alright so one day i was driving and notice that my temp. meter was almost at H... so i pull over and the first thing i check was my raidiator... n sure enough if was empty so i went n bought some n pour it in n, it was all better... after a few more days i check it again and it was empty again but its not leaking under? so i figure its leaking into my block im guessing that's a blown head gasket? any clues on how to do a head gasket job? what i need and whats the process of changing it out? someone told me that its harder then expected cause you gotta line out your pistons and do all these good stuff? any advice?
