How much gas do you have in the tank?

oldManTan

you're supposed to let it run and give it some gas while plumes of white smoke come out the exhaust, did you do that? and then change spark plugs afterwards once the car has completely stopped smoking.

What oldManTan said. I've Seafoamed about 10 cars over the years and all of them ran a little/lot rough until it burned off. I usually take them out for a short drive (5-10 minutes) and make sure to mash the gas a few times until no more white smoke comes out.

I have a little under half a tank..do I need to drain my old gas out?

unknown101

Yes I did that..but after the smoke stop..took it to drive for about 5-10 min...car started to slip like rev high...so I drove it home..and changed the sparkplug and oil the next morning

You should be fine there.

And by slip do you mean clutch slip?

Any Other suggestion?

just let it use up the gas, put the old plugs back in, the gas still has seafoam in it you don't want it to foul the new plugs already. it might be a good idea to change the oil again not the filter though. it's best to do this with a nearly empty tank.

I had a carbon buildup problem, and I ran a bunch of seafoam through the booster line, got the smoke show, and still had the carbon problem.

I then used the oldschool method of squirting some water in the intake with the engine revved up and hot, and the resulting steam cleaned out the engine with no smokeshow just the actual carbon smoke making its way out (like 1/4 the smoke of seafoam) and in half the time I spent seafoaming it I had actually cleaned the inside of the combustion chambers some. (note I have a map sensor setup I did not spray down my maf with water).

there is always the chance of hydrolocking an engine when putting water into it, but after seeing the youtube videos of people basically pouring water into the engine and it still running, I gave it a try with a little squirt bottle, and It hardly made the engine even stumble and after a few minutes of letting it take some water in you can see the steamy carbony exhaust smoke coming out the exhaust.

anyways just thought I would share the old school steam clean method is what worked for me. I got tired of the sea foam smoke show and not getting any results. I am not responsible to what you do to your car so use any water at your own risk just like everyone else, but it can work and have good results when done right.

I am just glad I didn't have to pull the head to clean the piston tops for my carbon buildup on the piston problem.
If you have engine sludge from using DINO oil or going to long on change intervals, steam clean does not help with that, for that you do use the seafoam in the oil but be sure to change it as directed.

^^ I had thought about that, sounds scary but, it's no different then meth/water injection. Have you seen the inside of the head at all since then? Any obvious cleaning?

oldManTan

it's pretty crazy seeing people just stick a hose in their intakes lol, but i guess it works! also, if it's ever really really foggy, go for a spirited drive, that should help as well lol.
