I used seafoam religiously on my old 97 Cobra. The 97 Cobra had these race like split port heads with two ports per cylinder. The geniuses at Ford decided to only spray a single injector into one port so the other non sprayed port would get tremendously gunked up.


On a warm engine (important) I would slowly rev the car while dumping about 1/3rd of the can into the pcv valve. Before doing it I would cut a 20oz soda bottle in half using my leatherman and fill that bottom portion with seafoam. I did that because the pcv valve line on the Cobra was only about 4 inches and thus it was too short to suck seafoam from anything other than a small container.

For that car it was very important that you let the motor die with seafoam still rushing in. I would keep revving the car while it went in and when the bottle had about a 1/2 inch left I would plunge the pcv valve hose into the seafoam and signal my girl to stop revving. The car would die as it choked on the last bit of seafoam. That way it was coated on that dry intake tract and the valves.... since air normally quickly sucks the seafoam through.

After it died I'd wait about 15-20 minutes depending on how bad I thought the gunk was. Then I'd immediately start it and quickly hold the revs up to about 2500rpm. After 5 or 6 seconds I'd go up to 3500rpm and let off. A bunch of white smoke would start pouring out. Then I'd rev it up to 4500rpm and hold it for a few seconds then go up to 6500rpm and let off without holding it up there. A TON of smoke would come out.

Then I'd basically snap it up to 7000rpm almost to fuel cutoff (7200rpm on the 97 cobra) and then let off. Usually by then that was the peak output of smoke and the car would then be good enough to drive without causing a massacre. I'd go for a quick cruise and really beat on it hard. Once the smoke completely stops you're basically done and it literally was worth a *lot* of horsepower on that car. Like 2 or 3 times the normal kick in the seat from doing an oil change and air filter change.

I haven't tried it yet on the Evo but I can contest to it's effectiveness on my Cobra. I did that every 15,000 miles and it made a huge difference.

ill try seafoam out one day.

never used it on the evo.. but used it on plenty ka24de 240's and my jeep cherokee classic with 218k on it.. it was a pretty epic experience.. smoked out the whole block lol.. its important to change the oil shortly after but im sure that was already discussed

have you checked your spark plugs to see if it left any deposits if any? I know that when I checked my Lucas "Octane Booster" my plugs were black as hell so I eventually stopped and I was a newb then but anytime when I put any cleaner in my tank I always make a way to check my plugs to check everything is good! just some input to keep in mind bud

really glad it worked for ya

Sorry to sound like a newb, do you have pictures of the vac line that you are putting the seafoam into? Also putting it into that vs the engine would clean what parts that the gas wouldnt?

Thanks

This might answer a few questions and give a little more info also.

Seafoam IS E85 approved! That's good news for all that run E85.
I would like to see if this would dissolve the mysterious black gunk that some people get on their injectors when using E85. Since I don't get this on my injectors, I can't test it for the forum.

I have used seafoam for 14 or so years (Gas and E85). I've also used it all 3 ways listed on the can (Intake, gas tank, crankcase). My own suggestion is to use it in the intake manifold and gas tank.

NOTE: I guess I better add a disclaimer. Do these steps at your own risk. You accept all responsibility for what you do to your vehicle.


Gas tank Instructions. (Will basically clean tank, injectors, valves, cylinder area, etc)
1. Pour in half to full can of seafoam
2. Fill up your gas tank
3. Let it work over time as you drive your car

Note: You will not see smoke pouring out your exhaust with this method


Intake Method. (Will basically clean the intake mani, possibly injector tips, intake ports on the head, valves, cylinder area, etc)
1. Warm up the engine
2. Locate a vacuum source on the intake manifold. One method is to use a spare piece of vacuum hose aprox 8 to 12 inches in length. Unplug the blow off valves source at the intake manifold. Plug in your spare length of vacuum hose to the manifold. This spare length will allow your to easily reach the can of seafoam.
3. Let the engine idle.
4. set the can of seafoam within reach of your hose. As the engine is idling, slowly put the hose down into the seafoam. You're trying to slowly suck in a little at a time. It's a little like skimming the top. You will probably have to blip the throttle to keep the car from stalling. You can do this by using the throttle cable. DO NOT just dunk the hose and start sucking the can dry quickly.
5. Monitor the amount you're sucking in. I probably suck in about 1/3 the can.
6. Shut off the car and let sit for 10-15 to let the seafoam do it's job.
7. Start the car. The car may not just start up instantly. Just crank it a few times and it should start up. It may sputter at first. This will go away as it's working all that stuff out of the engine.

Note 1: This is where the 007 smoke screen will probably come into play. It will smoke large amounts until it blows all the carbon and other stuff out of the car.

Note 2: If your engine has extreme buildups, there is a possibility that you could foul your plugs. I would check them to make sure.


Crankcase Method Since I'm not a big fan of this, I'm not going to put the instructions up. You can follow the instructions on the can. I will tell you I would not suggest you drive or put any load on your engine with it in the crankcase. Yes seafoam is a cleaner and lubricant but it's thinner than your oil. I would not suggest any load being put on your car when there's a possibility that this may thin out your oil. This is mainly use at idle, drain oil, then new oil and filter.
I may be wrong but do this at your own risk! I prefer to be safe than sorry.

These are the basic, quick and easy instructions.

As far as the questions about does it really work and have you used a scope to see in the cylinders, etc:
As I said above, I've used it for about 14 years. I've seen the before and after of the piston tops on my own engines. It was a night and day difference. I also had the TB off after a cleaning (TB gasket leak) and the inside of the intake mani was also spotless. Unlike the before that had black buildup throughout the mani.

I would take pic.s but my car is apart right now. Sorry!

I could have sworn I did a "How To" about this a long time ago. It may have been back in my 2G days though...hmmmm

Hope this helps.

Seafoam is awesome! Works every time for me.
