Quick Seafoam question.

I am going to seafoam my 2000 Ranger 4.0L tomorrow before i leave, it has about 120k miles, and i dont think it ever got such a treatment before.

So i was wondering if i could use an entire Can of seafoam through the brake booster vacuum hose to get more cleaning power, half a can in the gas and the other half in the oil when its about to get changed?

And should i start pouring the fluid in the vaccum only when the engine is warm?

Thanks

Careful with the speed and amount that goes in thru the booster vacuum line.

Do not want to hydro lock your engine and break/bend things.

If you haven't looked at youtube for all the videos on seafoam, I would highly recommend you do.

Yeah i checked that, but i was just asking if an entire can in the vacuum would be bad.
 
To answer your question, yes to both. Use 1/2 in the oil and let it run for 10-15 minutes at idle. Run half the can through the booster vacuum hose. Let it sit, then restart the vehicle after 30 minutes.
 
What problems are you trying to correct??

Some folks think you should only put in the gas tank! Cleans more things that need cleaning, leaves things alone that maybe should be left alone and no danger of breaking things.

IF you are just doing it for grins, you can cause problems you don't currently have by putting any of those magic solvents in the oil if the engine is really dirty and you don't need them if it is clean. Pull the oil fill cap and PCV valve off and look at them. If they are clean (or pretty clean) on the inside you don't need it. The same can be said if they are really dirty, it might be best to leave it alone. Sort of like seeing a snake sleeping in the sun and saying, "Let's poke it with a stick and see what happens!!" :icon_rofl:

My truck only gets 13 mpg in city, and i never try to exceed 2k RPM when i accelerate, people claimed to get up to 17 in town and 20-21 in highway, i cleaned TB, MAF, IAC, new air filter, done throttle cable mod and i cant improve mpg, plus the truck has some difficult climbing a hill, full throttle and it cant barely hold 90kph.

So far ive read a lot of good stuff about the seafoam, and some other say that seafoam is a bad idea...

But would an entire can in the vacuum be really more benefit than an half can?
 
Well, i just did it but there was no smoke, only a tiny bit at startup for about 1 second but then nothing.

Heres how i did it.

1.Warm up the engine

2. Ask a friend to hold rpm to 2K and make sure it wont stall

3. Pour really Slowly about 1/3 of the bottle in the brake booster vacuum line.

4.Stop engine for 15 minutes, replug hose and add rest of can in fuel tank.

5.Start it and rev it up, no smoke or hesitation.

Did i do something wrong? Maybe i added the seafoam too slowly? Took me like more than 5 minutes to poor 1/3. Or too much RPM?

(By the way, i didnt poored the sea foam directly in the hose, but in that thing between the brake booster and hose, maybe thats why the truck wanted to stall so easily?)

No smoke just means that there wasn't much to clean up inside the intake.
 
Ah well, i tried again but this time i added half a bottle and poured it in faster, nearly stalled truck twice, this time there was smoke, but not much.

I will wait to add in crankcase untill i need a oil change, would the other half can be too much? How long should i drive before changing oil if so?
 
Adding it to the oil is not going to help mpg. it'll just wash all the carbon and sludge into the oil filter, like its supposed to. thats only really intended if you have sticky lifters, ect. I sell seafoam services to customers all the time at our shop, the way we do em is half a can in the vaccum hose, drive it until it quits smoking, dump the other half in the tank. I'm always leary about shutting it off directly after pouring in seafoam as it doesn't do anything. It works better at operating temp :icon_thumby:
 
It only smoked for about 15 second, so i guess i failed again.
 
If that's your reason for doing it, there is something else at fault that a can of Seafoam won't fix.

But yes, you did it correctly and that's all there is to clean. Part of the can in the gas tank and 1/3 of it in the crankcase (when about to do an oil change) is fine.

But be warned that it might knock crap deposits, grit, and sludge loose that could clog your journals for oil delivery if you dislodge too much at once.
 
Under 200K that motor is still a baby. You probably got all your gonna get especially the second time. The first time I did my 2.8l it clouded up the neighborhood and the follow up it barely smoked. Bring it up to temp and suck the seafoam in at a rate the motor almost stalls and quickly shut it down is the key otherwise it just blows out the exhaust and cannot dissolve the carbon on the valves, rings and piston tops. If you was to check the compression before and after the treatment then you w0uld know what effect if any occured. The key is to shut the motor off as fast as possible and let the chemicals do their job.

Ah, i stopped the truck like 2-3 second after the last drop, that might be why.

By the way, does the guy inside the truck has to keep the gas pedal alway at same level? or he has to make sure it wont stall?

And does the brake booster gose really does lead to all cylinder?

Go in thru the throttle body
