Does it actually do anything?

Some people swear by it. I never tried it. I was going to but after reading all the mixed opinions I got confused and decided not to.

I have used it in lots of different vehicles, including a 50's ford pickup. cleans the carbon right off the pistons! just pull your brake booster vacuum line and let the motor pull it in from the bottle. do that for about a min or so then let it take enough in to stall. restart and watch the smoke from your exhaust as all the crap blows out. you can also add it to the gas tank and oil. If your going to add it to the oil though do an oil change afterward.

dependent on how much carbon buildup is in the motor, it can help quite a bit.

here's the full procedure:

- Buy 2 cans of Seafoam and 1 can of Seafoam Deep Creep spray.- Put one can in a full tank of gas- Put half of the second one in your oil- Drive 100-150 miles.- Park the truck and pull the vacuum line going to the brake booster.- Start the truck. The idle may be racing, or it might not want to idle at all. If it's idling high, don't worry about it. Right now you have a huge vacuum leak. If it's stumbling, blip the throttle by hand enough to keep it running as you do the next step.- Trickle 2/3 of the remaining 8 oz of seafoam down that line. You may need to have a friend there with a hand on the throttle giving it just enough gas to keep it running.- With the final 1/3 of the remaining half can, now just dump it down the vaccum line. This should kill the engine. If not, shut it off ASAP after doing this.- Use seafoam deep creep spray and pull the air intake tube, push the throttle butterfly back and spray about 1/3 can down the intake and let it sit as well.- Reassemble your intake and put the brake vacuum line back on.- Let the truck sit 30 minutes.- Start the truck back up (it will start hard)- Let the truck idle 15 minutes. If it doesn't want to idle, work the throttle a little bit to keep it running, but do not rev hard on it during this period. The truck may smoke a considerable amount during this time. Don't worry, it's not going to hurt anything.- Go out and take it on a drive - flog it. You'll make lots and lots of white smoke.- After a few wide open throttle accelerations, the smoke will clear and you'll end up with a better running truck. This cleans all the carbon buildup on the inside of the engine.- Lastly, change your oil. This will be the blackest, nastiest oil you drain out of your truck.

This stuff is a petroleum product and will not harm sensors, cats, etc. I know it's weird to think about dumping something like this in the oil, but with the difference it made on my car, I'm sold on this stuff. The pinging went away, as did a flat spot in my rpm range under acceleration. The car also is idling a lot smoother.

i tried seafoaming my ka d21 and when i pulled the brake booster line the truck didn't have enough power to stay on

to be honest i have done it before on other vehicles through the brake booster and oil and used as a fuel treatment i hardly got the results as when i used the actual machine that automatically puts it in the fuel rail for you.

but to each their own

but i have heard having a heavy foot clears out carbon lol

Sure, about 100-150 miles will be fine in the crankcase. The general measurement is a shot (1.5 oz) of seafoam for every quart of oil.

I just did this on my truck to help clean the crankcase. Don't worry, it's not gonna flatten out the camshaft for ruin any engine bearings if you use the right "oil to seafoam" ratio.

Okay my brother (being the wise mechanic that he is) told me not to put it in the brake booster vac line cause it will destroy my engine.. also I cannot find the deep creep seafoam

Your brother is wrong.

If you dump a whole bunch in at once, it can hydrolock the motor. You trickle it in. It won't hurt a thing. I've done this several times on several vehicles from Nissans to LS1 Chevys.

Deep creep spray is basically seafoam in an aerosol. Most parts stores that carry seafoam will carry the spray too. I've found it at Autzoone.

Okay! Thanks Desert rat! I'm going to drive around today once I put the stuff into the oil and gas. Also I just put some Foglamps *from Auto Zone * on the bumper next to the headlights and it really looks good and helps with the low beams

I am somewhat against seafoam. I have heard of cases where it degrades performance since carbon can help improve compression on worn cylinders sometimes. It will probably do more good then bad in most cases, but I don't like chancing it.
