seafoam does it work?

[lil_Blue_Ford]

I was skeptical of Seafoam until the first time I tried it. I don't remember exactly how I fed it in, but it was either through a front vacuum port or IAC or something. Fed in half a can slowly while it was running then shut it off. Waited 15 or 20 minutes, started it up, got a little smoke but not really anything much. Was kind of disappointed.

Well, about a half hour later I had to go somewhere so I jumped in the truck, idled up the driveway and started down the road. THAT is when the smoke show really kicked off... it was midnight behind me for a good half mile or so, put out more black smoke than a diesel with the fuel turned up too high.

I always thought it involved driving my truck into the sea on a windy day...but I now realize it comes in a can so I don't have to drive 1,500 miles to get to the nearest sea...

If it was called "Lake Foam" I could have done it around here for free...well, except if the motor hydro locked on me...

Think my motor needs a can of it about now so it's on my list...

Seafoam is one great product. You get the best results when the engine is at operating temp. The hotter the carbon inside the more seafoam will absorb and break it free.

I use it primarily in the fuel tank on vehicles seeing as it cleans the injectors and gets sprayed in before the intake valves so it cleans from the injectors to the cylinder. Occasionally if the engine is real high mileage when I get it ill run it for a good 2 hours then suck the seafoam in whichever vacuum line will best evenly distribute it throughout the intake manifold. Suck the whole can down and then shut it off for a good 15 minutes preferably on a hot day so the engine doesn't cool down to much. Then take it for a hell ride for 10 minutes to suck it all through and out.

Seafoam is a great product if used as intended.

If you are not familiar with it or this will be your first time then watch the you-tube videos on the proper techniques.

There are even videos there by Seafoam the company.

If you use it on a dirty fuel tank, seafoam will help clean that too but clog your fuel filter or possibly your pick up screen on internal fuel pumps.

Most tanks aren't that bad.

I like using it thru the brake booster vacuum line, fuel tank but not the oil since it thins it out.

Lots of people have used it in their oil it's just I prefer not to.

Yeah and it can really annoy your neighbors LOL.

I remember someone did it and drove down the highway and it was literally james bond smokescreen.

Yep it works. If you wanna do the full job, get two cans...one regular and one with the little red curved/looped hose attached to the can. Save the regular can for your next oil change, simply follow the label directions. The newer cans with the U-shaped hose connect to your intake after you take the intake/air hose off...you put the end within half an inch of the butterfly/throttle in the intake, put the air hose back on to hold it there, put the other end of the U-shaped hose onto the spray nozzle of the Sea Foam and then run the rpms up a little while emptying the spray can into the intake through the U-shaped hose. Much better than drenching the top end through the brake booster vacuum hose and you don't have to work too hard to keep the rpms up and the engine running. Follow the label directions, then you shut it down for 5 minutes and wait...then start it back up, watch the moskeeto fog at work pouring out of your tailpipe...then run it down the road hard for a few miles and back. When you do your next oil change, put half of the regular can in your gas tank and use the rest in the crankcase after you drain a little oil out...run it for a few miles/minutes, let it cool then do the regular oil change and filter. I've used all three ways and it works wonders...also great on two strokes, like outboards and other small engines that haven't been worked or put under load correctly and are acting punkish due to carbon crud buildup. You can use ATF the same way, but the sea foam is more convenient to dose/use.

My old 3.8 Pontiac Bonneville developed a terrible valve tapping. I put the Seafoam in the tank and it cleared it up completely. I remember using 2 treatments. The tapping went away and never returned. Seafoam worked for me. That Pontiac was 1 of the worst cars that I've owned.

always worked well for me no problems great product i always do it to my friends car when they ask me to change theyre oil for them
first time it freaked them out with the smoke show lol

hey while we are on the topic... ive used seafoam on my 01 dodge that I hated and finally got rid of and it worked great on that truck, i just put half a can through the brake booster vacuum line got some white smoke while pouring it in, shut off for 30 minutes, started back up idled for 5 minutes or so randomly reving the engine. No smoke. Took it round the block couple times, still no smoke. Let it idle for another 5 while parked and randomly reved it. Still no smoke. This is my first time using seafoam on the 92 ranger and am surprised there is no smoke show. If I dont plan on driving the truck again until saturday will it be bad if there is seafoam in the motor for that long? Can any damage be done to the valve seals etc letting it sit that long with no smoke show to verify that it has burned the seafoam off?

I did the seafoam treatment on my 93 in the driveway a couple of weeks ago. It smoked a little while getting the seafoam, and a little after I started it back up but no big smokescreen. I wouldn't worry about any being left in there...just drive the hound out of it and enjoy.

If it idled properly that means there wasn't anything left in the intake. The smoke cloud is from the carbon and such being broken loose and burned off. The lack of a cloud indicates that the top end was already fairly clean inside, which is a good thing.

awesome! good to know. I did also add some into the oil but I didnt anticipate seeing smoke from that perse. However Im saddened that seafoam didn't help the rough idle which means I no longer get to be a lazy mechanic and I start looking for the cause.

Agree with Kimcrwbr1, have used seafoam since my first car 40+ years ago. have never found anything to top it. Dad used to put it in all vehicles and farm equiptment and it always made them run smooth and nice even on the John Deere model B (still have it and it still runs great.

i'm thinking of running this through the motor because i'm getting the truck smogged in a couple weeks and the trucks been sitting a while. would would that be a good idea? also i've heard that putting it in high mileage vehicles can actually cause damage because it breaks down so much stuff in the engine and some of the gunk built up in the motor could be holding it togther. is there any truth to that?
