I have been using seafoam in heavy equipment engines for years and I have seen it make dramatic differences in performance and idle quality. I recently had a problem with low power from my 91 talon. It felt like the computer was removing timing. Normally what I do is find a secluded spot because you will smoke down your whole neighborhood. Start the engine and let it get up to opperating temp. I remove a vacum hose and put it in the can and rev the engine to about 2500 rpm and suck the can dry. Shut off the engine and let it sit for about 15 minutes. Then start it back up and run it down the road, and run it hard. This will remove a substantial amount of carbon build up from the combustion chambers. :thumb:
 
Heres a really really stupid question. When you guys say you put it in the crankcase oil you are putting it in where you put your oil in at during a change right??? Because when I do this I'm going to suck some up through the manifold put some in the gas and I want to put some in the oil to make sure I'm getting everything.
 
ok.. so you put 1/3 of it into gas, 1/3 into the pcv , and thats it? let it stand there for about 10-15 mins then turn the car on, and i don't drive my car around just rev it till the smoke clears up, and after that change oil, and and turn the car on for about 10 mins, and change the oil again? is that right? and no oil in crankcase? correct?

There should always be oil in the crankcase any time the crankshaft is rotated at any point during this treatment.

It's...

1) seafoam treatment procedure
2) drain oil
3) refill oil
4) drive car until engine is hot
5) drain oil
6) refill oil

This gets all the solvents out and keeps the internals lubricated throughout the process.

I would never put something like MCCC (others have compared the two products in this thread) in my fuel or crankcase. I can't determine if others felt the product was similar or if they were just referencing the procedure... but when I was messing with MCCC, I dipped my fingers in oil, applied a drop of the MCCC and when squeezing/rubbing my fingers together, I felt the solution become non-slippery.

If SeaFoam is approved for use in the fuel system and crank case, then feel free to use it that way. I know it comes in several varieties. If you want to treat and clean the whole fuel system, I would use a fuel system-approved product like BG44K. It's expensive, but it's safe and very effective.

Call me paranoid, but I want my car to achieve antique status and still run. I'm critical of solvents that degrade rubber and plastic, or that dissolve carbon and break down engine oil.

EDIT: Seafoam is nothing like MCCC. Just read the product info for the second time in years. It appears to be a different formula than I remembered it being 7 years ago. The previous seafoam product I had used was only for use in the combustion chamber and intake tract. MCCC is highly-caustic and requires safety handling procedures during its use and immediately breaks down oil to a non-viscous useless sludge.
 
I think im just gunna do half in the intake and half in the gastank. My car only has 65,000 miles on it so putting it in the intake should sufice, by the way what is this all cleaning when put in the intake besides like the valves,lifters and such.
 
putting it in the oil wont increase compression, oil has nothing to do with compression. it will break out sludge and other crap from your oil which will let it rev easier. when you seafoam your combustion chamber, it cleans the carbon and shit off your pistons and anywhere else in the chamber which will help reduce unnecessary compression, which will reduce detonation and in turn the ecu will pull less timing.

if your car is prone to leaking oil, it can get worse after seafoam because it cleans the sludge thats holding the oil inside the seals.
 
so if i have a leak and do seafoam it will most likely get worse. . but would a leak sealer help or not no more because i took off the old junk.
 
I remember when I started having problems with my car. It was immediately after I went to Oil Can Henry's and had them do their oil flush additive. My car started leaking oil from several different locations. Keep in mind this was on the stock motor with ~130k miles. If your seals were fresh then I'd be more likely to risk it. If your motor is old, the .001 horsepower and .2 mpg increase of adding it to your crankcase isn't really worth the risk of ruining your oil seals.
 
oh geez just read the can and do what it says, if you suddenly start leaking oil, the leak was there before you just didnt know about it/ or couldnt see it, so there for you should thank the sea foam for it has served two purposes, clean your engine, and found your leaks which you can now fix to prevent any further harm to your engine, i just sea foamed my engine 2 weeks ago i put some in the gas tank, some in the engine oil, and then sucked up the rest into the intake, and everything was fine, and my car has 160,000 on stock everything and no i dont baby her. just read the instructions and you and your car will be fine :thumb:

I don't understand how possibly making your car leak oil is beneficial. It's like picking at a scab you can't see (say on your back). What is this? Pick-pick-pick. Oh now I am bleeding I must of cut myself in the past. It is a good thing I picked that scab so I am now aware I cut myself and didn't realize it sometime in the past. So now you are bleeding for no good reason. The reward is you get to fix oil leaks which weren't effecting the operation of your car in the first place. If that oil leak is behind your front main seal then you won't realize oil is leaking until it drips out or you inadvertently slip your timing belt. I'm not saying it won't help, but I am saying that if your car starts leaking oil... which mine did... is it really worth the minute benefit. I haven't read through the 600+ posts in this thread but I don't imagine putting it in the crankcase nets nearly the same benefit as cleaning the combustion chamber & intake.
 
i have not read all the post either but can you honestly say that the sole reason for your car leaking oil was because you used sea foam? your car either had the leaks and you didnt know about it, or it was just not noticable yet, or you had a prolem that hadnt showed its big ugly face yet and the sea foam forced it out, like hmm builed up on a bad gasket or a seal? the sea foam cleans the build up or carbon or sludge or whatever and oh ya look ya got a leak, im not trying to be a jerk but come on are you really trying to say you can see every inch of your engine all the time and you know exactley what every gasket or seal looks like?:hmm:
 
but like i stated before if you read the instructions you will be fine and the instructions say to divide the can into the fuel/oil/comustion chamber. so to get the full affect of using the sea foam yes it would be benefitial to put it in your oil.:thumb:
 
I will admit I can't see every bit of my engine. However I can say that it did not leak oil in a detectable(on the pavement or the visible parts of the motor) amount prior to the additive. Yes I am stating that there were bad seals where the oil had formed deposits/gunk/crust holding the oil in and that the oil flush treatment did indeed remove those deposits and caused my previously non-leaking engine to start leaking oil in more than one spot. Were these going to be problems in the future? Probably. Were they right then? Absolutely not. What it did was make those potential future problems into problems right then. The car was 14 years old with approx 130k miles on it and I am saying that putting this stuff in your crankcase is not going to save your motor, it will not rejuvenate it, and it will not make it significantly faster. So why? A motor that doesn't leak is a motor that doesn't leak. I don't care if it is held together with powdered pistons and dried coolant, if the motor runs well and doesn't leak then seafoam in your crankcase is not going to make a noticeable change for you. It may not even make it leak but if it did, would it be worth it? I am not trying to be rude and I didn't say that the car would absolutely leak. I said that there is a risk that this could happen as a warning from a similar experience. Any motor of similar age and mileage is most likely going to have deposit buildup are around the seals so the risks are far greater as the mileage increases.
