I used Sea Foam on my Dakota yesterday and figured I would make a post. It's actually very easy.

1)Start car engine and wait until warmed up.
2) disconnect main vaccum line (see pic below)

3)SLOWLY pour 1/3 of the can into the vaccum line. The engine will turn off if you pour too fast.
4) Turn off engine
5) Pour 1/3 of can into gas tank
6) Pour remaining 1/3 into crankcase
7) After 10-15 min start engine and rev the engine then drive for 10-15 aggressively but legally (white smoke will come out the tailpipe)
8) Done

 

I really want to do this to my truck soon. As I am not a mechanic, I don't know where some things are located. Where is the main vacuum line on a 4.7?

 

I believe that it would be in the same area as the first pic?

i just seafoamed my dak the other day.

 

All Dakotas to my knowledge are the same as the first pic. By the way def. made a difference. My truck has 220,000 so it needed a cleaning. I am going to do it again in 2-4 weeks

 

You need to change the oil very soon after this is done BTW

 

no you dont, its a petroleum based product. their website even says so.

 

I wasn't sure if you do or not. I just changed my oil and was gonna do the seafoam but was told I shouldn't do it til right before I change my oil. I'll have to look into it a little more.

Edit: Yup just read their faq and it says it's fine to use without changing your oil.

 

"The most frequently asked question about using Sea FoamŽ is as follows: “After using Sea FoamŽ in my oil, fuel, or through the vacuum line (to clean carbon from the combustion chamber) do I need to change my oil?” The short answer is: No you don’t have to change your oil after using Sea FoamŽ in any application.

When using Sea FoamŽ in your fuel or through the vacuum line for carbon cleaning your oil does not need to be changed. Using Sea FoamŽ in your oil, at 1 Ŋ ounces per quart, is a safe way to clean a crankcase, free up rings or free up sticky lifters as you drive. Sea FoamŽ is not a chemical engine flush and therefore, it will not damage internal engine components or plug the oil pick up screen. Sea FoamŽ is a pure petroleum blend with no chemical additives and is safe for long term cleaning or short term pre-service cleaning.

Sea FoamŽ is a blend of highly refined additive oils and is compatible with all motor oils including synthetics. It is safe for all internal engine components and will not affect any seals, gaskets or o-rings. Sea FoamŽ cleans oil deposits and varnish in your crankcase by safely/slowly re liquefying the old oil residue so contaminants may flow and be filtered. The longer Sea FoamŽ is in your oil the cleaner your crankcase will become. When adding Sea FoamŽ to clean oil, for long term maintenance cleaning, you must check your oil periodically for color and clarity, when your oil looks dirty change it. Because you added cleaning oil (Sea FoamŽ) to your oil you may have to change oil before the expected service interval.

When adding Sea FoamŽ to dirty oil before an oil change, for best results use 1 Ŋ ounces per quart of oil at least 100 miles before oil is changed."
