i have used seafoam for a long time. myself and tom j. have both had issues with nasty old fuel in the tank. what fuel was in there had dried up. left varnish in the tank. put a few gallons of fuel in it, and what do ya know. that crap makes tar on the valves, sticks, and ruined pushrods, lifters, valves, ect. im sure there are other people who have had it happen. its HORRIBLE when you get so excited you got a motor running, it runs for 15 min or so, then BANG you got valve train issues because of crap in the tank. now, i get the motor running out of a 5 gal gas can with fresh fuel with seafoam in it. once motor runs good, i FILL the fuel tank and put 2 cans of seafoam in it. works great. cleans everything, no varnish nothing. even works on my 2 efi cars i got. every 5k or so i run a can thru. cleans injectors and all. once in a while you see a chunk of carbon fly out the exhaust. even on my '97 mountaineer 5.0, and my '03 dodge peon 2.0 you see carbon fly out with the seafoam. dave stohler www.picasaweb.google.com/das24rules _______________________________________________ AMC-list mailing list AMC-list@xxxxxxxxxxxx http://list.amc-list.com/listinfo.cgi/amc-list-amc-list.com
