My friend talked me into putting Seafoam into my gastank...WHOA!
My truck is smoking like a chimney now!
Good Lord- what's that crap doing to my truck!
Wish I never had put that stuff in there.
He also tried talking me into putting another can in my crankcase and straight into my carb.
The can into the carb will make it smoke like heck for a little while. Did you follow the directions on the can?. I use it all the time and have had nothing, but good results. It will knock loose all the deposits and blow them out the tail pipe as smoke.
i do hope that the OP and the guy who used marvel mystery oil realize that that is how those two products work. white smoke from the exhaust=clean motor! thats all gunk and crap in there that being burned out. marvel, yes you will see a drop in fuel mileage while it cleans everything out. its just how the stuff works. did some seafoam in the intake of my 91 460 and turned the campus parking lot into one giant smoke cloud. im not even kidding, you couldnt see ten feet. then it smoked for about five minutes while i drove it around town. runs better now.
I used seafoam on my old chevy, I made a vacuum line drink it out of the can... do that when it's warm and let it sit for a while... then run the engine until it stops smoking... can't say if it helped much since the truck still ran like crap...
