oops, i just read a bunch of info a reply to a past post of mine.. seems like some good stuff, does anybody have any additional info or know anybody that has used it? i just finished reading all the info i could handle.. i am no mechanic.. but it seems i just go to autozone, see what products they have and try it out! makes me feel a lot better than my previous options(head gasket repair, engine replacement) i will let you all know how it works out.
