Thread: Seafoam

  1. #1

    Default Seafoam

    ok, ive read about this seafoam stuff a couple times before and was wondering what it is and what it is used for and if it is worth buying (sounds like it is worth it already but just want to hear some opinions)

    the 1st time i heard about seafoam was in the motorcycle world. i was told it would eat the varnish out of the carbs and get a sitting bike back on the road in no time. i remember getting the money order for a case as it was only sold thru mail order and by the case. i put some in the carb bowl and the fuel tank and let sit for an hour and be hold the bike did start and run (smoked like heck for a bit) now 25 years later i still use and love the product and it is avalable at any NAPA and some larger auto chain stores. i use 1 can in the gas tank when at 1/2 full or 1/4 full. i then pull the booster vaccum line i was told i do it wrong but i i not had issues i pull the booster line and insert it into the can of saefoam and suck it in and let the motor stall (the correct way is add a funnel to the vacc line and pour slowly into the line and turn off the motor after 2/3s of the can is installed) let sit for 10-20 min and restart the car. it may or may not smoke (my kids love it when it does---and yes the smoke will stop, but sometimes it takes 20-35 min-i stop traffic for awhile and we laugh and 2Xs the fire dept has come out to investigate a fire
    about 50 miles before the oil change (oil, gear or tranny) i put the recomended amount in the correct spot.
    if you got alot of miles you might get a new fuel filter and change it after 250 miles cause your old one might get full of crud...........mike

    Sea Foam works great. I keep a few cans around to clean fuel systems on cars that have sat a while and I run it in my daily drivers about every 6 months.
    It does a great job cleaning clogged injectors, I've pulled clogged injectors and let them set a 1/2 hour in Sea Foam to clean up, works great.
    I usually run a 1/2 can in the gas tank and the other 1/2 in the vacuum booster line (actually any vacuum line will work great). I've never tried it in the oil yet because I use a sepparate cleaner for the oil just prior to oil changes.

    its worth every bit, at about $5 a can? I used 2 cans on my truck. I believe you put a can in a full tank of gas, half a can in your oil with about 150 miles left till you change it, and the other half in the brake booster line. With that last half for the booster line, you take one third(While the vehicle is running), pour it slowly and DO NOT let the engine die. Do this again with another third. Then with the last third pour as quick as you can to try to kill it and if the engine doesnt die, shut it off quickly. let it sit for about 15-25 minutes. Start it up and run for about 10 minutes. And for my favorite part, go for a little spirited driving and watch behind you as all of that buildup comes out your exhaust. It a lot of fun trying to make a huge trail going down the street. We did this in my best friends WS6 and had about a half mile trail of smoke. Have fun.

    did the seafoam treatment today in my truck and it smoked like a you know what as it was supposed too. the truck felt much smoother after the treatment and it seemed to have a little more pickup. it was also more responsive and it seem to have a little more pickup and be more responsive.

    I made movie of it as well ill post it up when i figure out how
