Seafaom is fun
 

As the description says, I let it sit overnight instead of waiting 5 minutes, since it had 77k and hadn't been cleaned yet. This is about 15 minutes after I started the car. After the cleaning, the high, bouncing idle disappeared and I got some power back. The idle dropped back to 550 instead of 1000+RPM, which was the big thing I was hoping for.

The wind noise isn't as bad as I thought it would be since the camera was pointing back, so you can both hear and see when I really hit the gas. Pedestrians and other drivers were giving me strange looks the whole time I was out :D

I've been thinking about doing seafoam in my explorer... but havnt figured out a good place to put it in...

some of the people on the explorer forum say the brake booster line... others say that doesnt reach all the cylinders... and no one has offered a good alternative place to put it in... so I just havnt done it...

Back in the day, we used to dribble a little automatic transmission fluid into the carburetor opening to clear out carbon builup that caused detonation. That was always a fun job.

JStrider, from what I've been told, the pcv valve hose is a good point to introduce the Seafoam.

Are you guys talking about the stuff I normally use to free up frozen nuts and bolts? I've only seen it in a spray can if it's the stuff I think it is. I usually get it from NAPA.

PCV hose on 5.0, 4.6, or 4.0SOHC
Nope, this is the motor treatment, not Deep Creep.

well I did it... didnt get as impressive of a smoke show as you did... but got some...

put it in thru the pcv... slowly poured half the can in got some smoke while doing it. then killed it... it kept running on its own for a couple seconds. then I let it sit for about 20 minutes... fired it up and drove till it stopped smoking

dont notice any difference in performance... dont know if it had ever been done before...I know it hasnt been done in the 4 years/30000 miles I've owned it.

I've used it on my F150 a couple of times, when even I feel a shudder from a spark plug fouling I do it. It cleans the spark plug as well as buildup in the cylinder. The first time I did it I got the massive amount of smoke, it was pretty fun.

So how do you "properly" use Seafoam?

Is it best to use a funnel and pour it through the tube connecting to the PCV valve? Or does it matter if you just pour it into the gas tank during a fill up?

Right before an oil change...

Park outside. Pull the plugs and pour ~1oz in each cylinder. Cover the plug holes with a rag(s) and bump over the engine ever so slightly. Just a tap. (distributes the cleaner around the rings) Replace plugs and let sit at least a few hours. No driving. Next morning, warm the engine (still no driving) and draw dose in via vacuum hose or pour it directly into the throttle body - without stalling engine. Expect a cloud. Let it idle for 5-10minutes, shut down, change oil & filter. Really. You don't want the seafoam in your crankcase for any length of time.

Pouring it into the gas tank will help clean your fuel system, intake, and might do a bit for the combustion chambers. It'll also drop octane a bit which you may feel as a performance change for the better or worse.

Pouring a small amount into each cylinder and allowing a soak clean the compression rings and can make a big difference on higher mileage cars.

It all depends on the condition of the vehicle. If the car is recent or in great shape you may not notice any change at all.

If you have a carbureted engine you can remove the airfilter and pour it directly in. Just watch out for blowback.

It's a fuel injection engine.

Thank you for the step by step Destruct. When I feed through the PCV tube twards the fuel injectors what's the best way? Is there the plastic IV style (purchasable at AutoZone or other store) gravity feed to pour it into the running engine? Or so you simply use a paper funnel doing the best you can?

when I tried it on my Subaru WRX, I turned into freakin Spy Hunter. I ripped out of the neighborhood because of all of the smoke and I had a poor motorcyclist following me for over 5 miles. Everytime I threw the clutch in and revved it up, smoke came pouring out. So when I went out with my Integra I went to an empty park. Almost no smoke, that engine was clean. Both times through the brake booster line. Just dribble it in so it stumbles but doesn't stall.
My question is did I cover the top end on my Subaru with it's horizontally opposed engine? Will it circulate all the way through, or just clean one side? The brake booster goes to one side of the engine.

Use the suction of the hose to suck it right out of the bottle.
Bah, you wasted it, not just on one side, but on one cyilnder. You need to take out the PCV valve out with the engine off (19mm wrench,) run a rubber hose into the hole (make sure it seals or your engine will stall,) pinch the hose, have someone start the car, then dip the hose into the can. once it's all sucked in, the engine will stall, which is your cue to put in a new PCV valve (those things are a pain in the ass to get out, might as well do it while it's out, especially if your intake needs cleaning.) Let sit, then start the smokeshow.

When you'ore doing this, it's a good idea to clean the throttle plate for maximum gain.

Any potential hazards or dangers with using seafoam? This stuff is pretty corrosive, right? Anyone had a bad experience?

It isn't as bad on paint as brake fluid but you wouldn't want to spread it around. Basically naphtha and alcohol. It does burn easily so watch ignition sources. Like most nasty fluids try not to touch or inhale it.

Trust me, I would not put anything corrosive in my engine. It'll strip paint if you leave it for a long time, but it's pretty safe. Don't breathe it and don't get it in your eyes or leave it on your skin.

If I need the carbon clean out I drive the shit out of my car (I do that everyday its not broken) or hold the throttle half open and pore a can of Coke in the carb :D
