where does 'sea foam' go?????

s2gots · February 13, 2007

Alright, so I do feel stupid asking this question, but I cant figure out what hose it is that the sea foam goes in. I sprayed the deep creep in the TB, I got that down.....but where is this vacum line Im supposed to use??? Anyone have pics of it???

I'm not 100% positive, but I believe you can use the hose coming off the brake booster, or there should be one coming off the TB as well. Either one should do.

EDIT: The line that I believe is coming off the TB is mostly hidden behind the intake.

Thanx TheClassic....one thing though...I dont have that brake booster!!!!!Its just the master cylinder. The only hose that comes off of it goes to the power steering pump. What the **** is going on???

Does this look more like your engine bay?

yes...thats it!!!

Look at the top left corner of the TB. Do you see that elbow with the hose connected to it? That's it. Just disconnect the hose, and stick it in the bottle of sea foam, or funnel it in a little at a time. Whatever the directions say.

Is it the rigid hose, about 3/8"??? If so, which end do I remove? The end on top of the TB, or the opposite end?

The black hose at the end of the elbow should come off with a little work. Since your truck is seven or eight years old, it might be a little hard.

You have Hydroboost power brakes meaning your power assist comes from the PS pump instead of a vacum booster.

You can also use the PCV line to pull in the seafoam. There is really no great way to pull Seafoam into these engines. The SF is going to take the path of least resistance and most of it will end up going down 1 or 2 runners in the intake. Some will get into the other cylinders but not a great deal. The Deep Creep is the same product just in an aerosol. If you can get it into the TB while running the engine, you will likely do the most good as it wll distribute the product more evenly. As long as you do not have the electronic Throttle, you can simply drill a hole in your intake tube just before the TB. Insert the straw of the DC can taking care not to let the straw suck into the engine. Run it at a fast Idle and spray away. When finished, plug the small hole with a sheet metal screw. I have been told this is not safe for a late 02 or 03 and up with Throttle by wire. It can damage the electronics in the throttle control if the DC go into it. I am not sure how it could get in there, but one of the Techs on this forum cautioned us on this.

I used the PCV to pull the SF in, and the deep creep via the small hole method....I was LOL when all that smoke started to pour our after I started it up....but Thanx for the help, I appreciate it!!

ive heard in the past about "sea foam" what exactly is it? is it recommended to do? how often? and would it help my 06 to gain more power or is this just to clean out the engine?

s2gots · February 14, 2007

mostly to clean it out....being you have an 06, I would not think you would need to clean it?? I have 130k on my 99, figured it cant hurt!

Jerry, it is petroleum based product that is designed to clean carbon and build up from the combustion chamber and valves. They make some other claims as far as cleaning gum and varnish from the engine when added to the oil, stablizing the fuel like StaBil does etc etc. We (CARQUEST) sell it by the tanker full and have been doing so for 10+ years. I have never heard of one customer complain about the stuff and have literally heard hundreds of very positive comments about it. Some people say that it is priarily made up of Naptha, an agent that dry cleaners use in their dry cleaning process.

I feel it has it's place and when used by the instructions, almost every user will tell you their vehicle runs better. If your truck is low mileage and you have been using a good high quality name brand fuel, you would likely not feel a lot of difference.

For general combustion chamber preventative maint., I prefer Chevron's Techron. An expensive product but when added to the fuel every 3,000 to 5,000 miles, it will do as it claims.
