How do I replace engine gaskets?

I know absolutely NOTHING about vehicles, but I need very specific step-by-step instructions on how to do this. I have a 1988 Plymouth Grand Voyager with a 3.0L V6 engine. Keep in mind that 1) I have no choice, because this is the only vehicle I can legally drive and my uncle is forcing me too, due to a bartering agreement of the utmost importance, 2) I don't even know the parts of a vehicle, much less where they are located or what they do, and 3) Please no "it's too hard" or "it's just not worth it" or "you're an idiot" blah blah blah. I HAVE NO CHOICE. Please, either tell me a VERY good website or e-mail me some pictures and instructions. Please, I need help A.S.A.P. Thank you.
