Question about using Seafoam

Brian,
I used the seafoam today. After I disconnected the vacuum line to the brake booster, I slowly poured about 1/3 of the can into the vacuum line. I then shut off the truck for about 5 minutes and then restarted the truck. Make sure your truck is outside or in an extremely well ventilated area when you do it. I also put a can of it in my gas tank.

Thanks.
I actually gave mine two smaller doses. One thru the brake boost vac line, and one through the line that goes up to the firewall to the evap fitting thing.
Made lots of funny smelling smoke.....
It does seem to idle better now. Haven't driven it so I can't say about that.
edit: HEY! just realized you are new to FTE. Glad to have you here and hope you stick around. It is a great web siTe with lots of good people.
Welcome!

I put 5oz in a glass container,have someone in the truck,and let the brake vacuum line ingest it.As soon as its gone I have the person shut it down.Wait 15-20 minutes,start it up,smoke out your neighbors,and go drive on the interstate 3-5 miles to blow the rest of the crap out! Come home,change the oil and poor the rest of the SeaFoam in your tank!
The reason I use a glass container is,the first time I did this I stuck the vacuum line in the can and the vacuum was so strong it sucked the can flat! LOL!!!!!!!!

Thomas,
I am - generally speaking - not a big fan of "miracle in a can" type stuff. But....Sea Foam seems to work!
I too had developed a slight bit of ping using 87 octane, under certain circumstances.
I have not noticed any pinging since the Sea Foam treatment. Even allowing for the placebo effect, I'd say it made a difference and was worth the $8 I spent on it.
I really wasn't expecting to see any difference but it seems to idle smoother and "run better" (how's that for a vague description?)
I plan to keep it up.

Thomas (or anyone else),
I wondered....by using the brake boost vac line, does that allow the Sea Foam "equal access" to all intakes? The vac port is on the port side, near the rear. I wonder if that allow the Sea Foam easy access to cylinders fed on the opposite side of the intake.
That question/concern is why I repeated the process using the vac port that ties in just under, and just after, the throttle body. I'd think this would be more likely to allow for the most equal distribution to all cylinders. All cylinders get their air thru this area and it just seems to make sense that they would all get a more unform dose of Sea Foam if it is administered thru this point.
Comments???

I do believe the Sea Foam will get sucked into all cylinders regardless of where it is injested. When a cylinder on the opposite bank is drawing in fresh air, it is pulling vac on the brake boost line as well. So, it is bound to pull the Sea Foam in - to a greater or lesser extent than cylinders nearer the vac port for the brake boost.
Regardless, I'll use the other line in the future. I disconnected the vac line right at the fire wall and put the Sea Foam in. This line goes straight in to the intake directly after the TB.

Since it was asked about in a different thread;
Here is how I did it......
Sea Foam Treatment for 4.2
Run the engine until warm.
Turn off engine.
Locate vacuum line leaving the bottom of the intake just behind throttle body. It should terminate into a connector located on the upper portion of the driver’s side of the firewall. (You should see a tag with “evap” on it, and a screw-on cap.)
Use a flat blade screwdriver to pull back the two sides of the retaining ring that holds the vacuum line in place.
Once removed, insert a small funnel or similar device into the vacuum line. (I used a 50cc syringe without the needle.)
Start the engine.
While holding a med-fast idle (2000-2500 rpm) slowly pour 5-6 ounces into the vacuum line. The vacuum will suck it in fast. I poured ˝ the dose in and waited approx 30 seconds, then poured the rest pretty quickly (the engine will bog down slightly at this point) and immediately shut the engine off.
Wait approx. 10 minutes and restart the engine.
It will make a lot of smoke. Rev the motor to clear at all the smoke.
Drive as normal now.
NOTE: as an option, you can use the vacuum line connected to the brake boost assembly. Remove tension form the clamp ring attaching the vacuum line to the check valve then remove the line from the check valve. Administer the Sea Foam thru this vacuum line.
