Seafoam???

yup, workes wonders. ATF will do basically the same thing. It makes lots of smoke.
 
It's all about "garunteed to pass". Garunteed to pass smog or double your money back. I just put some in my truck after my buddy had a good experience with it. My truck starts right up now in the morning and runs better than it did I think
 
I use it when I am getting a rig running thats been setting for a long period. seems to work good for that.
 
Yeah, but ATF will usually kill a Caty converter. I used the seafoam to clean mine out when I was having a nagging ping problem, and plan to do it again after I put on a few more miles.
 
I've used it on my '87 and on my wife's 2000 Tahoe when she hit 100k. Both with good success. On my wife's Hoe the SES light came on for a while but it cleared. I bet it was one of the 4 O2 sensors reacting to all that smoke coming thru the pipe.
 
pull the line off of the brake booster and hold your hand over it. makesure the engine does not shut off and put it in the can of seafoam and let it slowly suck up the seafoam. then shut then engine off and let it set for maybe 20 mins. there ya go. happy smoking up the neighborhood

How exactly do you get it into the engine? Just pour it into the throttle body or carburetor?

I pulled the hose off the throttle body hat goes to the pcv valve and used a piece of hose I had laying around. Put the hose on the vacume port and into the can and had my wife start the rig (after warming up with about a 10 miniute drive prior). Sucked in about 1/2 the can and had her shut it off. Let it sit while I hand luch then came back and started it up and ran it out. Drove around for 10 minutes and repeated.

You should have seen the crap come out of the pipe on the 2nd cleaning!
 
On my K5 I poured it down the throttle body since I know it will hit all the cylinders. On the Hoe I pulled the pcv tube, spun it around, set a small funnel in it, and poured into it.

Carb should have PCV hose as well, or use the power brake port. If all else fails you could pour it in as well. I think the can has instructions.
 
I'm confused. If it puts out a bunch of smoke I take it you have to let that clear out and drive it right to the DMV for inspection? Whats it actually doing to the internals?
 
I asked this question a while ago, and if I remeber corectly some said not to use it because it will screw up the engine because the carbon being cleaned off made it dirtier in other areas or something like that. I could be wrong though.
 
yup, seafoam rules.. we use it HEAVILY in the marine biz...

I just shock treated my K5 with 2 cans to the gas tank and it cleared up a sticky injector... It's also good used as a fuel maintenence item, throw a can in the tank 3, 4 times a year...

And yup, does wonders for combustion chambers too with a direct dose...
