sea foam help

[solareclipse 27]

hey guys just wondering if someone has a good write up or something with how to use sea foam? i got a new cat on my eclipse and the guy at the muffler shop said to get the system decarbonized. so where are the best places to put it in at???

Half a can in your gas tank. Drive like normal.
Half a can in your oil. Change oil after 100-200 miles.
Half can sucked into vacuum port on throttle body. Use a rubber hose. Keep engine rpm about 3k.

Don't forget to change your oil and plugs after using it!

The best and most effective way is sucking it in through your intake. It's easiest to have someone inside the car trying to keep it running cause it will try to die. Get the whole bottle in there and then shut the car off and let it sit about 20 minutes. Then fire it up and haul ass until you don't see anymore smoke...then change oil and plugs.

def search the forums, it's all over the place

i use 1 can in gas tank
half can in crank case
half can through the BOV line to the TB, best one ### it's out in the open and long enough to go in the bottle

I personally dumped the whole can through the BOV-TB line. Ran it hard and long for 10 mins or until the smoke cleared, then changed the oil. A representative said that changing the spark plugs were not necessary so I didn't. Runs fine.

Oh, last 1/2 can split evenly poured into cylinders and left over night. Be sure to crank it with the plugs removed before starting the car to prevent any chance compressing left over fluid.

After this and after the vacuum line method be sure to rev it up. Take it for a rip roaring spin around the block until the smoke clears.

so it is best to use two bottles.
i dont think it has ever been done before.
my eclipse has about 150k on it also.so it should be ok
to use it.

I copied this from an old post of mine. It was in the context of finding an exhaust leak on a turbo car but the general principles are the same.

1) Get car up to operating temperature
2) Have car idling
3) Remove vacuum line from BOV. Since you now have a large vacuum leak the motor will idle rough as if it is going to die
4) Stick the end of the hose into the can of Seafoam so that the vacuum is sucking it up. Don not allow it to suck up the whole can in one shot. Do maybe 1/5 can at a time or just until the motor wants to shut down. You may need a helper to give it some gas while you are doing this to keep the motor going. If you have exhaust leaks the smoke will start revealing them right away.
5) In order to hit the IM more evenly you may want to do some through the hose that connects to the PCV valve as well. It is too short to extend down into the can so you may need to temporarily replace it with a longer vacuum hose for the treatment. But since your main goal is to identify exhaust leaks as opposed to cleaning out your IM this is not a necessity.
6) After about half the can has been sucked up allow the motor to suck up enough so that it stalls
7) Let it sit for about 10-15 minutes. Even while it is sitting some smoke will continue to develop and work its way through the exhaust so that you can continue to identify leaks.
8) Make sure all vacuum hoses are hooked up. Start her up and take it for a spirited drive. You need to open it up a little to allow the residual chemical to burn off.

BE WARNED. Your exhaust is going to smoke like crazy. You may want to do this when it is getting dark so that your neighbors don't freak out. Try to stay on backroads with little traffic if possible. You'll see what I mean about the smoke. Don't worry, it's normal and expected and will burn off.

Make sure you do this in a well ventilated area! Don't even think about doing it in your garage!

If you have an old set of plugs sitting around you may want to put them in for the treatment and then reinstall the good ones after your all done.
