On the bottle of seafoam it says to have a certified mechanic make sure the line you are using services all cylinders and each make/model can be different. So, I want to do this the correct way but does anybody know if the brake boost line services all cylinders on the 351w? Also, do you guys just get a small funnel and pour it right into the line or what? I'm kind of nervous about doing it

 

Yes. The vacuum line off the brake boosters tied into the ENTIRE vacuum system.

Pull it off and "feed" the line a of sea foam a little at a time until the whole bottle is gone. Then shut the truck off and let set for 15 seconds. Reattach vacuum line to booster. Then start it up in WELL VENTILATED area and go for a ride. it is going to smoke like a B I T C H

 

Haha yeah I know. It's pretty windy here. That's why I'm gonna do it today. Still trying to figure out where. A park where there are no women or small children around lol

 

When I did my truck with the way the intake was designed some of the fluid kinda puddled up in the intake so I drove my truck up the road and as soon as I pulled out the driveway all of it flooded into one cylinder and it blew white smoke out the tailpipe like crazy. Smoked out the whole neighborhood like that and some guy passed me right as it died down and gave me one heck of a weird look. Don't know if it actually worked but hey it was cool looking.

 

Lol well yeah it blew all that gunk out.. My neighborhood is close together. I don't like it but there is no way I would do it at home. It wasn't as built up 4 years ago as it is now and just too crowded. If I did it here I guarantee the cops would be here

 

Forget the neighbors and let it rip! I wish we all could do that some days, basically just find an empty area near home and do it there is my advice.

 

Thanks, I ended up doing what you said. Went out near a cornfield where no cars were around and parked. Took the booster line off and put about 2/3s of the sea foam in a paper subway cup. Bent the cup into a V and slowly poured it in. It wanted to die so you could only do a little at a time. When I poured it all in I shut the truck off but no smoke was coming out yet. Put the line back in and let is sit for probably 2 or 3 min then fired her up! Smoke started to roll and since the truck was already warm I revved her up real good! It took a good 10-15 times for it all to come. Id definetly recommend doing this on a windy day lol. New exhaust sounded real good too! I poured the rest in the gas tank
