Seafoam - 2nd Gen Photos

Standard disclaimers apply. The forum and individuals who post therein these threads claim no liability to damages and make no warranty or validity of information found within. Work on your vehicles at your own risk.

One of the easiest maintenance tasks you can do for your X is run Seafoam through it to clean it out.

What is Seafoam? We're not talking about the foamy stuff that forms at beaches, no what we're dealing with is

This stuff can usually be picked up at your local autoparts store usually for less than $10. Here's a description: Link

This stuff is basically a very high grade lubricant oil that will stabilize fuel and remove unwanted build up from other mechanical components. Adding this to a few components inside your engine will make clean out the fuel and oil system and keep your vehicle running strong and efficient. I gained an instant 3MPG the first time I ran this through my engine just to give an example.

The technique I use is splitting the can of Seafoam into thirds and applying one third to:
  • Brake Booster Line
  • Fuel Tank
  • Crank Case

A general warning: It's recommended that if you add this to your crankcase that you do it within about 100 miles of an oil change. It will most likely knock some gunk around and you'll want that emptied out of the system relatively soon so it doesn't redeposit itself.

The part that typically confuses most people is applying Seafoam to the brake booster line. There are other vacuum lines which may work just as well as the brake booster, but I've always used the brake booster as that seems to be the standard among most vehicles.

First off the brake booster line is the one that comes out from the drum on the driver's side of the vehicle:

With the vehicle running simply take a pair of pliers and pull the vacuum line away from the coupler. It may be on there pretty tight even after pulling back the clamp. Just keep twisting it back and forth and you may also find it easier to use something blunt on the end of the hose to push it off the coupler. The engine will immediately start idling rough. This is normal and it shouldn't actually die.
The vacuum line will have obvious suction on it. What I did was pour some of the Seafoam into a disposable cup and slowly feed it to the line.

At this point you may get a considerable amount of white smoke billowing from your exhaust. This is also normal. If your engine starts sputtering too much just ease off of how much Seafoam you're feeding it for a moment and then continue.

Once it's taken a third of your can of Seafoam, go ahead and reconnect the vacuum line and everything will quickly return to normal.

The other two areas are exceptionally straight forward. While you're at a gas station filling up your tank go ahead and add a third of the can to the tank before pumping gas into it.

And for the crank case you can add it directly to the oil reservoir. (As before it's a good idea to do this when you've got a oil change already scheduled so it doesn't go more than 50-100 miles for best results)

That's all there is to it. The inside of your engine will be cleaner, mechanical parts will turn better, fuel injectors will do their job with less impedance, your truck will love you more, and it cost you less than $10.

Good luck! ;D

I run a can every time in come back from Mexico. I put some in the oil just before I change it about 500 miles before. Great stuff.
