I hear alot about this stuff but have never used it , what is it suppose to do and does it really work ??? And how are you suppose to use it ??
 


I've used it several times on all of my car. I stand by this product 100% You'll be surprised by the results.
 
It cleans the carbon from valves and the combustion chambers. You let the intake suck it through and then let it sit. Fire it up 30 min. or so later and watch the smoke show, lol... The more smoke the more it cleaned. And yes, it really does work (not snake oil). I use it on all my cars and have yet to have an issue. It actually freed up a sticky lifter I had on my old 302 when I used it in the crankcase about 100mi. before an oil change. It also can be dumped into the gas tank to clean the fuel system. Well worth the $7/can.
 
You can youtube people doing it. It comes as a liquid or aerosol. I have heard so many good things about it, i just don't think yo ucan buy it in Canada. I have yet to ever see it.
But stories i have heard have all been good.

And yes, you run your car and it will smoke.. You'll think something is wrong, but its actually a good thing.. You repeat the process until you see no smoke.

Edit - i decided to see if i can buy it.. and yup, the partsource sells it.. so I will try it out and let you know!.
 
I currently have an oil leak that I am currently trying to figure out where it is coming from and I need to change my plugs and wires. Will it be okay to use Seafoam in my car while I still have these issues? I just replaced the EGR valve, so I am just checking to make sure this is not going to ruin the new part!
 
Don't use Seafoam on anything over 150 K miles or not maintained well. I used it on a Honda I bought with 170 K miles. Car didn't have the right plugs in it even when I changed them. Gave it a slight CAM sound though lol. But after running the Seafoam (I did the full treatment of gas tank, put in the oil for 100 miles before changing and running it through the intake), I had oil leaks and the connect rods started making noise. Sometimes that carbon is needed. It seems to fall under the same line of changing the transmission fluid and filter on a higher mileage vehicle. If it hasn't been done, leave it alone.
 


I did it on my unmaintained 192K mile gtp and didn't have a problem with it and it ran a whole lot better afterward.
 
Regal - As far as I can tell, the individual I purchased the car from did an okay job maintaining the car. The left the ERG issue alone (was throwing a code for ERG valve stuck open) for several months. So there was some carbon build up around the ERG mount and the spark plugs have a bit of carbon built up on them as well.

For the EGR, I recommend removing it and soaking it for a day with penetrating oil. Just costs you the penetrating oil and an EGR gasket will no ill effects.

If you do the Seafoam, follow instructions exactly as listed. Check your rubber hoses also. The Honda had some hoses eaten afterwards. If your car is supercharged, seek an alternate path for the intake portion of the process. You don't want to take anything off the supercharger rotors as you will loose efficiency. Do some searches on here and the web on Seafoam as it's been discussed a bit.
 
Its not supercharged and I just replaced all the hoses. I will follow the instructions exactly. I am assuming here using the PCV hose is going to be the best place to dribble seafoam into the engine and then put the rest in gas tank. This is what I am gathering from their website. Am I correct on this?
 
The only bad thing I've ever heard of it doing when put in through a vacuum line is fouling plugs in extremely dirty engines, and that's as simple as a plug change afterwards and no big deal. I've had positive results many times using it that way. It also works well on motorcycles (if you can find a vacuum line) FWIW.
 


On my motorcycle i just ran it through the gas line and it didn't want to run at all on straight seafoam.^^^
 
So should i run it through the T vacuum line under the supercharger snout? Or the middle vacuum line on top of it?
