just poured some b12 chemtool (basically seafoam) down the booster vaccum line in my 2.8. she didnt like that idea 1 bit, wouldnt even idle w/o throttle input with the line off. i did manage to get half the can in but wow i never saw the car surge so much on its own. i hope it works well, i think shes dirty on the inside causing some ticking, the motors only got 74k. anyone else use this?

 

seafoam is mostley water, chemtool is all chemicals. I use seafoam and swear by it, but i only use chentool in the oil before a change evrey once in a while.

 

I used some seafoam, car almost died while i was putting it in but runs alot better now.

 

Try a smaller vacuum line to administer whatever cleaner you choose. The brake booster line is a huge vacuum leak.

 

yeah chemtool was crap. i wasnt happy so i went out and got seafoam, what a difference, i almost smoked out my neighbor hood, car took half of the can before she called it quits with my girl on the pedal about 2500rpm. not much smoke on the drive, but it smoked like hell when i was applying it, i had to hold my breath for like 45 seconds and then when the car stalled my girl runs out into the house yelling that stink omg i cant breath haha because her window was down.

 

good to hear it worked for you, I use it on all my older, high mileage cars bout twice a year, half can or so each car. Always worked great.

 

i just tryed the seafoam, used 2/3 of the can put the rest in the tank. im skeptical i did see alot of smoke but so far no improvement in anything still runs the same as it always has. is there suposed to be an impovement right aways or does it take a certain amount of miles?

 

i swear by seafoam, i use it regularly in all of my cars. they always run bettedr after i use it, but it usually runs a little rough when you are pouring it in. after that they always run wayyy better.

 

since putting my crate motor in a yr ago i have only drivin the 91 rs 3000 miles......will seafoam benefit me any?

 

i just got some seafoam today if the break booster line is too big then what vac line do i use?

 

Seafoam is light oil, alcohol, and naphtha. No water.

 

I stand corected.

 

What are you guys treating ? Are you trying to get the carbon off the valves ? Will it affect the o2 sensor or the cat ?
