Hey, I just did a seafoam treatment on my honda, all went well. I will admit I don't know much about engines but got throug the honda like I said, I have a 2003 gx470 and it seems less cut and dry with that car. Can someone please give me some very detailed instructions on which one it is or a pic, I've been reading and searching various forums for 2 weeks to be absolutly sure and I am finally breaking down and asking for help. Thanks so much.
