Ok, so for a while I've been meaning to test out SeaFoam on my truck. Well, I finally got to it about a week ago, then got caught up with writing a thread on a how to.
All I hear is about running it through your Power Brake Booster line, or through your main vacuum line.
Now, if you look at the diagram of the vacuum routing on the core support that the MAIN VAC is the PCV valve. Now, both of those are so far back into the Upper Intake Manifold that they wont reach the front 4 cylinders. So, after crawling in the engine bay, I have found a very efficient and easy way to run it while hitting all 6 cylinders.
It's a nipple that hooks up onto your emissions system that runs to your charcoal canisters.
First you want to start off by removing one side of the intake tubing. Use a standard screwdriver.
If you want, you can pull the whole tubing but it's not necessary, just kind of lift it above the throttle body and let it rest there.
Next you are going to remove the emissions line from the nipple. It's located on the bottom right side of the throttle body.
Use a spare vacuum line, or use what I used. Take the vacuum line (black with yellow stripe) off of the upper intake box's bi-metal sensor. It runs down to a tubing that helps your engine warm up faster in the winter. I just used that because my tubing broke and therefore the line was useless.
Then plug it into the nipple.
Make sure you have the line clear of the belts, you don't want to catch it and tear things up lol.
Make sure you re-connect you intake tubing on the throttle body.
Next, set the can somewhere stable so you can use one hand to accelerate the engine and the other hand to feed the line into seafoam.
NOTE: This will smoke like crazy if it is your first time. I did mine for the first time outside my house and I was in front of my driveway and couldn't see my house at all (I really wish I could have recorded it...sorry guys)
This video is the second time, I only ran half a can and dumped the rest into my oil before an oil change.
Let it sit for 5 to 10 minutes. I put my sylvania 3157's in while it sat.
After that, make sure you pull the vacuum line you used, and put everything back together. Drive around for a while, maybe hit the interstate and blow all of it out.
P.S. - Don't hate the flaky paint...first time high temp project lol.
Good luck!!!
