Uhh.. You have a first gen, so I don't exactly know where the hoses are on the 3.3 engine. I just did my 2.7 a couple weekends ago, I believe I had it drawn in through the cruise control vacuum line. I could show you a picture but it wouldnt help much as you have a different engine.

I also poured some into my gas tank. I think the can reccommends 1 oz of seafoam for each gallon of gas in your tank.

I did not add any to my oil, I think that was the 3rd option on the can. Good luck.

since it comes in bout a ten ounce can, one can for your fuel tank will do, and one can to run through your engine. i have a first gen myself and i'm not sure which vacuum hose my buddy used to put the stuff through the engine if you have a haynes manual look it up in there to see where your vacuum hoses are. also be careful how much seafoam you add to your oil, don't put in too much since when you put the seafoam through your engine, most of the internals will already be fairly clean.

When I used it, I used the PCV hose, and a little in the tank.

IIRC, my can was either 16 oz or 20 oz. It is out in my trunk right now and I don't feel like going to look at it, lol.

i know about adding it to my fuel. so for that i use one once per gallon of gas i have in my car? i just had my oil changed 500 miles ago should i wait till i need another oil change and change the oil of the treatment? what pcv house do i use since i got the breather filter and do i have to remove the breather an put that pcv house back in for the treatment? and can someone tell me wich vaccume hose to use? and where is the cruise controll vaccume hoses located? would it be safe to run it in all these places at once or should i do one after the other? and what kind of seafoam do i get

1) Sea Foam / 12 oz. Deep Creep Multi-Purpose Penetrating Lubricant and Cleaner

i had the same problem when i joined this site. i mainly joined just to find out how to do the seafoam procedure. well i found out there aren't any good tutorials that show you step-by-step on how to do it.

theres one "tutorial" on this site that literally just posts the words on the side of the seafoam can. that was extremely frustrating to say the least. its also one thing to describe to someone how to do something, but its alot better if you show them.

i have a 1993 3.5L and i had to figure out for myself on how to do it. when i get around to it, maybe this weekend, ill post up a full tutorial including pictures on how i did it.

if you put the seafoam and suck it in through your pcv valve, your going to have to get an oil change because it will end up in your crankcase. the best way to do it would be through the power steering booster line or through the two vacuum lines that feed the intake manifold (how i did it). when i put the seafoam into the pcv hose, i was dissapointed when i didnt see any smoke at all, and nothing felt different. then i did it through the vacuum hoses and voila..smoke show!

i can now report that i am getting at least 3-4 mpg increase than before

I think maybe you are confusing the breather inlet with the PCV. If you use the breather inlet, then yes, you are pulling sea Foam into your oil. If you use the PCV valve, then it is going straight into the manifold, it never gets anywhere near the oil system.

The Intrepid has a 16 gallon tank. So just put in one full can and fill the tank and bingo: the ratio is correct. I have used two cans per tankfull of gas on a few cars that had all kinds of crud on the injectors, and it cleaned them right up and did not smoke at all.

On average, I put in one full can every 3K miles.

Thank You.
Maybe I should have been more clear, sorry.
Pull the hose off the PCV valve in the rocker cover, not the intake side.
It's a big/ger vac. hose and easier to pour in the "foam".
Plus, it's after the TB, but before the injectors on a 3.3.
Not so much you kill the car mind you, but enough to make it "stutter" in my case.
Gumout spray cleaner does well on the TB/butterfly.

I first put half in a full tank and i notice a difference in the power...... So about 3 months later i got the nerve up to put the other half in the engine, but i got no smoke at all... I heard that the 3.2/3.5L engine don't smoke or as much as the 2.7L engine which puts out the "smoke show"....

My 3.5 smoked so much the first time I did it that it chased away my mother-in-law and fogged up the entire neighborhood. Then it smoked like crazy for 10 miles on the freeway. It was the most fun I have ever had with a car. Ever since, it hardly smokes at all when I Seafoam it.

Yeah, pouring it in the tank will not clean the intake out.
You need to find a vacuum line, and pour the Seafoam into the intake..
