Sea Foam

[kevinw2345]

I have been thinking about using Sea foam on my 98 expedition with 211,000 kms and some change. Has anyone used it on their vehicle with this many kms. I have heard good and some bad stuff so want some fellow Expedition owners opinions. Thanks Guys

not the same thing, but i SeaFoamed a 1994 Ford E150 conversion van with a 302 and 176,000 miles on it. BOY did it give off a smoke screen!!!!!

Using it how? Fuel system, crank case before an oil change, top end cleaning such as introducing through your brake booster? What is your goal?

i did it through the brake booster method..

Using the SeaFoam to clean the top end will require you to use it either in the fuel tank at fill up or thru the brake booster or vacuum line feeding the manifold.

Putting the SeaFoam in the oil before the oil change is cleaning the bottom end.

It depends on your reasoning of use to where you put the SeaFoam.

A smoke screen out the tail pipes will only happen when you use it directly into the manifold, ie: brake booster or vacuum line. And that is a good thing, it is doing what it is supposed to do, cleaning deposit build-up in the intake, valves.

SeaFoam is meant to only clean up the carbon build up through the top end, and oil build up deposits in the bottom end when used in the oil.

I usually add a can of SeaFoam every 4 or 5 fill-ups. It does all good and nothing bad. It is a great investment as a regular fuel additive. Only downfall to this method I use is if there is deposits in the fuel system it could clog up injectors or disturb the injector spray pattern. Other than that, it is a safe and clean method to help keep the upper end clean as possible. I virtually swear by the product as I have been using it for years and on all kinds of makes and models.

I'd suggest a quick search of the forum. We've pretty much covered this subject to death.

i am pretty much just looking to clean it, i know sometimes when i stop the truck starts to shake like the engine wants to stall so i want to give it a good cleaning inside.

i know some people swear by it, some people dont. Thats why i asked for opinions i have a year warranty on my truck right now so if the Sea foam reveals any problems it covers all internal parts for the engine. Thanks for the in depth response.

i used it in the gas tank and oil. and i used it threw the vacuum brake booster hose and it didnt really set off a smoke screen. nvy said it put out some, but not much. i should have put in a 2nd can but i didnt have one.

That sounds kinda like a torque converter not wanting to unlock.... Or is after you come to a stop and within a few seconds after it does this?

its a few seconds after i stop. I can put it in park and it sometimes does it.

If its running and shifting good leave it alone

The smoke screen is created by the break down of unburnt and hardened carbon in the intake and valve train. The more it is able to break down, the more the white fog. It is wise after you let it run while you are dumping it in the intake, to take it out for a test drive. First take off in first for abotu 100 yards hard on the pedal. Then come to a stop and do it again in first gear. Repeat a few times then allow it to idle for a few minutes. The take off hard in first allows for high RPM and the ability to kick out all that carbon and throw it out the pipes. Usually I pour up to 1/2 can on the first run, then come back after the test run and repeat with the rest of the can.

Be mindful not to put it in through the brake booster too quickly.. Bad bad ju-ju could result just pour it in nice and slowly

That be true, you gradually pour it in, you do not want to bog the engine down to a stall.

This may sound stupid but does anyone have a picture of the brake booster line so I can run the seafoam through it? I think I know which line it is but want to make sure. I have a 2001 Expedition XLT.

Sounds like you start it up and slowly pour it in right? Thanks for any help on this!

 

[kevinw2345]

Thanks guys i used sea foam the other day, didnt put it in the manifold dont know if i will but i put it through the brake booster and the gas tank. Had no problems, had a little bit of smoke but nothing major.

Skyjumper is The Man ! , I'm Brucesexpo From Explorer forum and Skyjumper is very smart when it comes to these Expeditions and Explorers ! Think i Might try the Seafoam in the brake booster and in the tank , Kind of worried about blowing a gasket if i put it in the crankcase ? Not sure yet We'll See !
