Seafoam treatment

Nimrod · 08-22-2007, 04:33 AM

I want to do seafoam thing but not sure which vaccum hose to put it in. This is on a 3.4L Tacoma. Can anyone walk me through this? THanks.

Just find the brake booster line that runs into the master cylinder it should suck air when the engine is running and it is disconnected

p.s. I was skeptical for a very long time until I actually tried it and oh my what a difference I am a believer now

Wow, was fast. Thanks, that sounds easy enough. I will give it a try tonight.

Elton · 08-22-2007, 04:44 AM

poor it in slowly just dont go and stick the hose in the bottle

mkgarrison5 · 08-22-2007, 07:10 AM

or use the pcv valve. thats what i use and yes it works. have someone in your driver seat taching it to 1500 rpm to help suck it a little quicker.. then let it sit for hours then crank it and run it down the road.. just dont pull out infront of a cop smoking bc he will pull you lol... trust me. i about got a ticket. he was pissed

Tark · 08-23-2007, 07:10 AM

I did the entire seafoam treatment about 2 months ago:

1 can in the gas tank
1 can in the crankcase when I changed the oil
1 can sucked through the PCV valve

My truck runs like an absolute champ.

I allowed myself to chalk up 2000 miles w/ the seafoam in the crankcase w/ Mobil 1 and when I drained the oil, it came out a little redder than just normal oil.

I am sold on this stuff, and am always skeptical of any additives.

That said, go for it, the $4 or so per can is worth doing.

RunnerUp · 08-23-2007, 10:15 AM

2000 miles in the crankcase? wow, thats alot... i drove about 150 miles with it in the crank case and then changed it

but yes, the PVC valve is where i did it also, 1st time i just let it keep running after i added it and burned the first dose out that way, the second time i choked the motor out with it and let it sit for a half hour and blew plumes of smoke, 3rd time i let it sit overnight and wow... it was really thick smoke

this is the PCV valve and the side you pour it in, just pull that hose up and pour it right down that, but not too fast, and keep a finger over it when you arent pouring otherwise your engine stalls

mkgarrison5 · 08-23-2007, 11:02 AM

or you could leave the pcv valve IN haha. i do it that way, it doesnt stall. as long as someone is in the driver seat pressing the gas petal to 1500 or so rpms you will be fine.. take your time..

also whoever uses 1 can in the tank is wasting.. use in a concentrated form like 2-3 cans per 5 gallons and run till empty. THEN put 1\3 can or 1\2 can intervals through the pcv valve or brake vacuum line. the longer you let it sit the better it will work.. persoanlly i wont put that stuff in my crank case just oil

jrallan26 · 08-23-2007, 12:16 PM

Did any of you had to change the plugs afterwards??

RunnerUp · 08-23-2007, 12:18 PM

i changed my plugs afterwards, but i also had 100k on them, so they needed it... but i have heard of this stuff screwing up cat converters and plugs before

Texas_Ace · 08-23-2007, 12:20 PM

DO NOT DO IT IN THE BRKAE BOOSTER HOSE!

It only feed 3 cylinders and could mess something up. Do it in the PCV hose like said above.

frodin1 · 08-23-2007, 12:20 PM

Here's a video! Good luck!

infiltrator · 08-23-2007, 12:23 PM

yeah, you have to change your plugs and clean your o2 sensor... i havent done it but read too much about it hahah. i should be getting around to it in a month or so.

mkgarrison5 · 08-23-2007, 12:27 PM

i changed my plugs but not the O2 sensor.. mine is just fine and i have done it twice.. one time i changed the plugs and the second time i didnt. i dont see it being a big deal unless your truck is really gummed up bad. go ahead and do it. btw the first time i did it i had 80k miles on my truck. no problems at all. i took the plugs out and other than them being shot to hell bc they had 80k miles on them they werent gummed up from the seafoam..

RunnerUp · 08-23-2007, 12:52 PM

dude, after watching that seafoam video frodin posted... i want bug be gone, its cleans everything, and i mean everything, just watch the video!!

Gerdo · 04-25-2008, 09:10 PM

I'm going to do seafoam in the next few days. I do have a couple of questions.

I'm only going to use it in the PCV and in the gas tank.

Do I need to change the spark plugs?

Do I need to clean the O2 sensors?

Do I need to change the oil?

How long should I leave the seafoam fog in before restarting? 1 hour? 12 hours?

daytraitors · 04-26-2008, 09:20 PM

You shouldn't have to change the plugs unless you notice a loss in mileage or power or both. Given that you're asking the question, if you haven't changed the plugs for 100k miles, go ahead and do it; it's a cheap replacement. If you're doing it yourself, get a good socket and a 12" extension.

You don't need to clean the sensor if you're mileage or power are fine.

If you use the seafoam in the crank, you should change the oil within 500 miles. It alters the viscosity of the oil, so don't tow with a can of seafoam in the crank. That said, I can't imagine that the seafoam would actually remain in the oil after 500 miles. I figure it would have burned off by then, but that's what they say. . .

Leave the seafoam in overnight, or at least three hours.

daytraitors · 04-26-2008, 09:20 PM

If you feel like playing around, soak a bbq grill in seafoam for a few hours. . . tell me what happens.

pdyebrasil · 04-26-2008, 09:40 PM

I asked a couple of my mechanic friends what they knew about seafoam and both of them mentioned how they had recently had quite a few cars come in with messed up cats and injectors and such because their owners had used seafoam... So, if you're gonna do it, be warned.

That said, I did it about a month ago (before I talked to them) and felt a little difference, but not anything major. I don't think I'm gonna risk it again.

Texas_Ace · 04-26-2008, 10:51 PM

I would never use it in the crank, that is aksing for problems. In the gas, I use it from time to time, though i prefer things like lucus and RXP for that.

I will also use it in the PCV from time to time, it does seem to help some but then i will also be changing out my cat for a high-flow one pretty soon anyways so i am not worried.

Jdizzydub · 04-26-2008, 11:41 PM

Nice video and good thread..sounds like i'll be adding this to my to do list.

ozziesironmanoffroad · 04-27-2008, 12:08 AM

sweet im gonna put some seafoam into the carburator of my honda and maybe it will fire!

mkgarrison5 · 04-28-2008, 04:55 AM

GM top end cleaner is by far better than seafoam..

Gerdo · 04-28-2008, 06:56 AM

Do you use the GM cleaner the same way? Can you get it at the auto parts store or just GM?

mkgarrison5 · 04-30-2008, 07:25 AM

just GM. yes you use it the same way. except do not leave it in overnight AND CHANGE your oil after you burn it out. you should do that with seafoam too but GM is much stronger.
