I was sceptacle at first, but then I used it and WOW, what a difference on my 96 Cobra. It can be bought at most autoparts stores. I'm big over on www.stlmustangs.com, and if you post over there asking about it, you'll here about 30 people sing its praises. People say to put it in the gas, but then it's just like injector cleaner and doesn't do shit barely. I was told to use the PCV valve to suck it into the motor, so that's what I did.

Step 1: with the motor off, simply pull the PCV hose out of the DRIVER-side valve cover, but leave it connected to the manifold.

Step 2: Open the bottle of Seafoam (the fluid, not the aerosol spray kind) and put the end of the PCV hose into the can, while keeping the can as upright as possible at first. You'll need 2 people, one to hold the can, one inside the car.

Step 3: Start the motor for about 12 seconds. This will suck all the contents out of the bottle into the motor. The can-holder should signal to the person in the car to turn-off the motor as soon as the can is empty. The faster you turn it off, the better. You'll notice that the motor will nearly die when it sucks in the Seafoam, this is normal. Seriously, it'll work fine after the process is done.

Step 4: Let the car sit for 30 minutes with the engine off.

Step 5: MAKE SURE YOU ARE IN A VEEERY WELL VENTILATED AREA. This will cause quite a smoke-show. Start the motor, let it idle for about 30 seconds. The engine will be sluggish and want to die, but will usually stay running. After 30 seconds or so, raise the RPM to about 2800 and hold it there until you feel the motor start to rev more freely (usually about 20-40 seconds). This step makes lots of smoke. That is all the dissolved carbon blowing out.

Step 6: Take the car out for a spin. Go WOT as soon as possible. This should clear the remaining contaminates.

Step 7: Drive the car around at different speeds and RPM's until it feels like the car is running like normal. After 10-15 of driving, you should notice a large increase in power, more smoothness in revs, and an all-round better running motor. After 74,000 miles I did this, and it felt like the engine had gained 20 horsepower, even though it was probably just underpowered with carbon before.


A can of Seafoam is about $4-5 and the can looks old-school. It has ornate style writing and kinda resembles an old shaving-cream can. Ask the store people, they'll know. It should be by the injector cleaners, etc.

I just used this stuff on my 97 cobra that has 66000 miles on it and boy did it make a HUGE difference, trust me give it a try its well worth it.

Sticky por Favor?

I reccomend Seafoam along with BG's 44K for a good total clensing of the intake and injectors. Im getting ready to do a Seafoam treatment to the HRL since it just eclipsed 210,000 miles.

I agree, it's a good product. Nothing however compares to actually taking the intake apart and cleaning it and the IMRC's by hand Tim. I did seafoam twice before I took it apart and it was still damn dirty. There is just some gunk you have to scrape off.

i know but i'm lazy and can't seem to find the time, you should know me by now

[EVA-02 GT]

Hmm can anyone get a pic of the pcv hose where the can should get sucked up at ? I just tried and the liquid didn't get sucked up so I guess it was the wrong one

[Scottyboy]

Could I use this on a carburated engine?

Back in the day we use to use ATF thru the carb. RPMS to about 1500 and slowly pour a QT thru th ecarb it will billow white smoke but it will clean all the carbon deposits off and its about 3 bucks a can.

Yes, it works good with carb'ed motors.

so i'm up on doing this to my car but where do i find PCV hose???

its been awhile since i looked at a 4.6 but i believe it comes off the intake hose near the throttle body.

[blackicecobra]

Is it safe to use on an 02 GT. Thanks

Yup.

[ImpactStang]

so i read a can of this the other day, it says you can pour it directly into the gas tank. true or not and whats the difference between that and using it through the PCV directly? also said you can use in the oil too....

[bighoss88lx]

Pouring it in the gas tank cleans your fuel system (fuel lines, injectors, etc). Sucking it into your intake cleans your intake manifold, tops of pistons etc of carbon deposits.

The label pretty much says you can use it for anything. So far I have only run it through the fuel system on the boat, the beater and the stang.

[AdRock]

Seafoam is the shiznit.

I run Chemtool through the gas tank and SeaFoam through the intake. I just don't trust putting any of that stuff in the crankcase, never have, never will.

[sonicblue4.6]

Where is the PCV hose on a 94 GT??

[BlackSunshine01]

you can run it in the oil. i used to work at oreilly. i ended up calling up thier corprate dead quarters to see if it was more like a motor flush or what. the guy on the phone told me that you can run it as a flush or in the oil full time to help prevent deposits. but i have never personally ran it in my oil.

[cmschlatt]

so if i put sand in my air intake, that will polish it right?
