I've read some good comments here & at SCCoA about seafoam so I just bought my first can today.

It says to use it through a PCV Valve or a brake booster line. Where is the brake booster? I searched around this forum for a picture, but found nothing. Is it just the brake fluid container?

I plan to disconnect the PCV valve, stick a funnel in it, start the car (leave it on park), and poor 1/3 pint in. Is that basically it, or do I need to rev up or anything?

Which end do I stick it in?

Do I stick it in the vacuum tube or the other end? I assume the vacuum tube.... and I assume I cant just shove it through the pcv valve.... or could I leave the pcv valve on it?

Then ill put the other 1/3 in the gas tank, and the other 1/3 in the oil a week or two before I will change my oil.

Is this a safe method?

The brake booster is the round drum against the firewall behind the master cyinder (the brake fluid container) you put the seafoam into the vacuum line that goes from the booster to the engine.

Ummm....

Do not pour anything INTO the PCV valve. Unless Im reading that wrong....you want to let a vacuum line suck it in.

With the car warmed up:

On the back of the intake there will be a main vac line. If you follow it back to the firewall you will come to a distribution "block". Remove the vac line from this piece. Stick the hose in the can and slowly let it suck up the fluid while you open and close the TB; roll the rpms.



Once the engine has sucked up the desired amount shut the car off and let it sit for a minute or two. Start it back up and "blip" the throttle for a few minutes.

Dont be alarmed by the smoke. That is your reward for a job well done. :)

and also if it chugs dont be alarmed, mine does it every time, probably because I suck it up too fast. When I stuck the main vac line into the can it created a seal because the hose is the same diameter as the opening to the can, and it sucked up all the seafoam and crushed the can with the suction lol. It was awesome. I sent a huge cloud of white smoke over the main street of my town (I live on the corner of an intersection) and people gave me some funny looks and I was just like, "Yeah I removed the restrictor plate so the red dragon could breathe a little easier, but lets keep that on the downlow, its not exactly street legal." Okay I didnt do that last part it's a movie quote.

Thanks for the picture w/ text "AEDM8" ... was really helpful. :)

The "This Line" looks easier to get to... is that the brake booster? The "Remove Here" the PCV tube?

while you open and close the TB; roll the rpms.
Translation please? :D :confused:

"This line" is the main vac line. The arrow above "Remove here" is pointing to where that line eventually meets the distributor block, your PCV line also is connected to this block. The main vac line is only a few inches long. Remove "this line" from the distributor block, then stick the removed end in the can.

Roll the rpms: raise them by opening the throttle body, let them fall, raise them by opening the throttle body, let them fall, raise them by opening the throttle body, let them fall, raise them by opening the throttle body, let them fall,raise them by opening the throttle body, let them fall, raise them by opening the throttle body, let them fall....ect... :)

AEDM8 your making me feel like such a noob :( ... though I am and I don't mind learning so it's all good. :)

So I take the "This Line" pop it out and just let it sit there?

Is there I way I can rev up from the engine compartment, or do I need someone to hit the accelerator? How high should I rev up?

Look at the throttle body... theres a gold-colored bracket. move it, this will open your throttle.

Hey dont worry man. We all had to start somewhere. Im glad that you asked the question.

Take "this line" (the main vac line) out of the distribution block. The end you take off you will be putting into the can, or if you choose use a bowl instead, it might be easier to measure that way.

You can open the TB manually while under the hood. Just move the top arm back a little. There is no need to open it all the way. Half way open should be enough.

You could have a friend to help you, it would give you a free hand to hold the vac. line and the seafoam while they roll the rpms.

When you take the vac line off and start the car you might need to keep your thumb over the open end, this will keep the engine from dieing, start rolling the rpms when you start sucking in the seafoam. Once you have sucked up enough shut the engine off and let it sit.

Watch for moving parts. (I dont know why I feel the need to tell you that...lol ;) )

Thanks for the info. :)

I don't know what bracket your referring to, but im sure I could find it. Any chance you have a picture?

If all else fails, would it be safe to have someone just tap on the accelerate instead?

its really easy, the throttle body, which is where the intake tube connects to on the motor side, has a gold colored bracket on the front side that has some cables attached to it. You just twist it and it will open the throttle, same thing as hitting the gas. Try it out a few times while the car is in park and you'll figure it out. Just kinda snap it open a little and the engine will rev up.

I'm humbly confused now. I thought I put the "remove here" line in the can? Or are you saying I just pull out the "This Line" and put the "Remove Here" into the can?

Any pictures of this by any chance? I saw some pictures of people using seafoam and I didn't see anyone who had jacked their car. :-/

So I remove the vac before starting the car? Do keep the vac sealed off the whole time?

Thanks again. :)

the "this line" and "remove here" and the same hose. You remove it at "remove here" and stick it into the seafoam can. You can leave the vac tree (where you disconnected the hose from) open that wont matter. Just stick that hose in the can and start the car. It might die the first time you start it, I just start it and rev it up a little so it stays running.

Jay where did you buy the Seafoam? None of the stores in Canada, Canadian Tire, Wally world (or at least here in Manitoba) seem to carry it.

Please don't beat me, but where does the seafoam go when it gets sucked into your vacuum line? I understand the oil and gas applications, but not the vacuum line application?
