The best way is:
-park outside
-get a very small funnel
-find your brake booster (big round black part attached to the firewall driverside)
-pull the rubber hose off the brake booster (should be a compression clip, use big plyers)
-insert your funnel into the hose
-start the truck
-take note of the suction coming from your funnel
-open can of seafoam
-put your thumb on the can and slowly pour it down the funnel
-take note of the changing idle
-keep pouring, slowly increasing the amount and use half the can
-truck might stall
-(running or not) install the brake booster line back on the booster
-truck might stall
-if not stalled, turn it off
-wait 20-30mins
-start truck
-drive like you stole it

Whoala.

What do you do with the other half of the can? Gas tank or repeat the process on the next oil change?

Do what you want, I put mine in the oil.

I did the above twice now this weekend, thick smoke each time...loved that it was doing something

I'm sold on the stuff, check my threads

How many miles do you have on? I can't imagine it'd matter if it was a flex fuel engine. Would it?

I did mine yesterday, I used a smaller hose and installed it into the brake booster hose and used it to suck the fluid out of the can while my wife sat in the truck and kept the truck from dying (I had half a cans worth of seafoam in the can so I didn't suck out too much!!). That was the only thing different than what Boss did!! I basically did that with half a can, poured another half a can in the oil and poured 1/2 a can in the gas, my truck always drives better after I do all of that!! For those keeping track, I bought 2 cans!!
Talk about a white smoke screen, I went over to my neighbors house and advised them to close their front door and windows and I'm glad I did, I couldn't see thier house for the first minute of revving the motor!! ha ha ha!

I think I have 120k now.

Not sure I follow, I have a ff truck yes but don't understand ...fuel is fuel.

Thanks BOSS, your write up made it alot less confusing. I will try this once I get back to my truck. Its been a couple weeks. I still have a couple weeks to go till I get it back. Its in NH, I am in TX.

 

[Travieso]

boss so you pour the other half inside the gas tank or in the motor where the oil goes into ?

gas or oil...
i put it in both last time i foamed my hoe. that way through the gas it cleans the injectors..

if you really wanna clean your tank,injectors etc napa recommended me to use a full can with a tank of gas along with using half in the oil and half through the brake booster...

I haven't done much research on SF. I didn't think it'd matter on a FF, just thought I'd ask before I did it, messed up the truck and have somebody say "don't do SF with FF". Just covering my arse, hopefully.

I've been using seafoam for years in my truck. When I bought my Tahoe with 104K on the clock, it had bad cold start piston slap and knocked under load. Switched to M1 synthetic and started running a can of seafoam thru the intake before each oil change and after about two oil changes, both issues are basicly nonexistant anymore.

I do have some alternatives to Boss's procedrure though.
-Use the PCV line that runs to the rear of the driver side valve cover. This line goes into the top center of the intake, where as the brake booster is plumbed into the rear of the intake, providing for better distribution to each cylinder. The majority of the gunk you are tring to clean from the intake is comming from this PCV line in the first place therefor the heaviest concentration is going to be in the center of the intake where this line enters.
-Use a whole can in the intake and pour it slow enough that you do not have to touch the throttle to keep an idle. You don't want to risk hydrolocking the motor and bending a rod or valve.
-No need to pour any in the crankcase unless you are using bottom shelf oil and don't change it regularly. If you only use half a can in the top end, use the rest in the fuel to clean the injectors and any remainder left on the intake valves.
-I seafoam my vehicles the evening before an oil change and let it soak over night. If you don't have time, I would let it sit minimum 20-30 minutes as Boss suggested.

so today i wanted to seafoam and cant find the valve to put the seafoam into ? is it in these pics ?

Its the hose that you have your finger on.

 

[WhoDatPanic]

for sure ??? i am really confused dont want to put it in the wrong hole haha

 

[yukon23]

Yep thats the brake booster and if you run your finger a few inches back you will find the pcv line its the hard plastic tube going into the back of your valve cover you could pull it up off the pcv and slide a piece of hose into that one also just as BigKID stated earlier.

 

[WhoDatPanic]

so how do i get that freaking line i have my finger on off to suck up the seafoam ??

 

[WhoDatPanic]

im a ratard when it comes to my engine lol plz someone help me im going crazy haha i have had the can of seafoam for like 3 days but to scared to do ne thing because i dont want to eff up my hoe..

 

[Rivieraracing]
