Sea Foam

I used some sea foam today, And stalled the egine 3-4 times.. Man that is some touchy stuff! I first tried using the PCValve, and it stalled so I tried the brake booster line, and got quite a bit sucked up, but it stalled a couple of times.. then i dumped some i each Barrel (TBI) and stalled it. and i had enough of it, so i let it sit for 5 minutes.. dumped the 3/4 full seafoam in the fuel tank, which is completely full, started the engine, and there was some blue smoke!! so i rev'd it up quite a bit, roaring blue smoke, after 5-10 minutes it cleared up, then i went for a ride.

Now, a few Friends told me to use this stuff to clean out the carbon in my engine and CAT., But how do i know thats what that stuff did?

Anybody got any info on this seafoam stuff?

In my opinion the stuff works

I have used sea foam on a couple of vehicles and the results wer favorable. I never occured any blue smoke. The question in mind is what prompted you to use the sea foam in the first place? I am assuming that this vehicle probably has pretty high miles. I dont know what the vehicle even is. My experience was with an 84 ford van with over 200K miles and the only symptom was it just ran like crap. I dumped some sea foam in on about a 1/4 tank, the whole bottle, and it helped quite a bit. I rebuilt the carb and boom, problem fixed.
I hope I have provided you with some descent feedback.

Tim

Dump the seafoam in the crankcase and i THINK even into the engine's oil. I think you have to be very careful with the mix ratio when dumpping it into the oil. Confirm this first! I dont want you to complain about the KABOOM because of me

My Kawasaki sat in storage for a few years. It would not start at all when I took it out. I threw a can of Seafoam into the tank and let it sit for a week /the bkike kicked right over. Great stuff!

CLICK for the Sea Foam FAQ page. It covers everything you've just asked or were concerned about.

Briefly, the smoke is normal. Adding too fast will cause stalling, and in severe enough cases could lead to a bent rod or cracked piston from hydrolocking the engine (liquids aren't compressible, for the most part).

This stuff can be sprayed from a spray bottle (empty 409 cleaner bottle, for instance), right into the TBI w/the engine fully warmed up and running, w/o stalling it. But don't try to suck Sea Foam up a vacuum line like drinking a milkshake through a straw- the Sea Foam has to be poured into the vacuum line slowly enough that the engine "labors", w/o stalling.

After you're done adding it, take the vehicle out on the road and hammer on it (in a secluded, safe area- follow traffic rules and be safe) for a few minutes to get rid of the carbon, etc. that it knocks loose.

I swear by the stuff. I pour two bottles into my boat tank (90 gal tank) before I lay it up for the summer. Run it for about 10 minutes to get it into the carbs (150 HP outboard), then shut it down...so it sits in the carbs all summer. The engine runs as smooth as velvet when I get back in the winter. I do the same thing with my cars and small engines when I lay them up for the winter...

I used that where I work till I found real chemicals.

I use it in a pinch for upper intake cleaning. My preference is to slowly draw it into the intake via vac line. stall the motor. scrub the throttle body with a rag or brush.

Fire engine, rev it slowly draw in the rest of the can.


Great for cleaning carbon, intake, and valves; engines smoke like mad and run rough for a little while. Drive about 3-10 miles and you'kll be good to go.

Ditto on the outboard, I have a 24' Bennington tri-toon fishing rig with a 175 Mercury Pro Xs engine. ALL of the fishing and high perf. boat web sites highly recommend Sea Foam along with the Engine mfg's. gas supplement. I use a "cocktail" of the mix in every tank.......good stuff!! Now if your engine is really gunked up and you use the Sea Foam correctly it will look like a battleship laying down a smoke screen sometimes.

Used it when I started a derelict Triumph TR8 that I bought that sat for 8 years (215 aluminum V8). Worked great! Engine ran and even idled at 800 rpm until the dried out carb gaskets started spewing gasoline and i had to shut it down. Then it was time to clean up all the mouse turds that shot out of both tail paipes into my driveway!

It seems to work good for me in cleaning injectors.

To help decarbon my motor I like to mist water into the carb and do an internal steam cleaning. You can't just pour water down the carb or it will hydrolock. I had a crude water injection set up for awhile using a very restricted vacuum line. I put a hypodermic needle in the hose to meter the water. It worked great but I ran out of water pretty quick so I took it off so I didn't have a vacuum leak.
