You only let it sit for a few mins (5-10.)

 

This youtube vids shows how suck it through the intake vacuum...

The PCV hose it fine, but any vacuum line will work.

 

After reading this and many other SF threads, I decided to run to Wal-Mart and get a can to try. I decide to try it out on my work truck as a test vehicle before trying it out on either of my Vettes. I poured in about 1/2 can through the power brake booster hose using a small funnel. Put the rest in the fuel tank.

Engine stumbled a bit while pouring SLOWLY, but it took it w/o a real problem. The smoke started just before I shut the engine down. I let it sit for 5 minutes or so. Started it back up & got some more smoke, but less than I thought I would. What I am getting is a light bellowing of smoke @ idle and a puff when I throttle it harder.

What I noticed fairly soon was that a light, eratic miss at idle seems to be gone. I have 30 gallons of fuel or so to burn up, so I'll report back at the next fill up!


**note** Its worth noting here that I keep my work truck in top working order. I drive it everyday, and sometimes put 150 miles a day on it. I give it tune ups regularly and at the slightest sign of trouble, I repair the problem immediately. It has allot of miles on it, but it runs and looks much younger than it is.

Specs: 1995 Chevrolet 2500 4x4

just might give it a try come spring good posts thanks

 

Give it a good hard rev once you first start it and the smoke will be really thick. Hold the RPMs in the 3-4k range and watch the smoke show.

 

I swear by seafoam..... I used it first in my 95 Trans Am vert. Here is my experience:

I heard about Seafoam through the F-body forums, and like many was a bit skeptical... but hey for a few bucks why not. I ran it through the TA@ ~95k miles, using the vacuum line method. I actually used a whole can, and holy MOLY!! It looked like a forest fire in my little cul-de-sac. ALL of the neighbors came out to see what was going on. I kept her running and she probably smoked for ~10 minutes, then I went on a little run around the neighborhood, with a NOTICABLE increase in available power.

Being the skeptical person that I am, I wanted to figure out/prove how it could be a hoax. I mean, it could have all been in my imagination that it ran so much better right? "Placebo effect". And how hard would it be to make a liquid that smoked when ignited in a combustion engine? Probably not hard at all. It just so happened the perfect opportunity arose... I had another vehicle of mine, while I was away, break down on my house/car sitter. The dealer was my only recourse, and part of the "fix" was a full fuel system cleanout (to the ridiculous tune of over $500). As soon as I got back, I got a can of seafoam, and performed the exact same procedure that I had done on my TA, to the other vehicle (with even more miles). Absolutely NOTHING came out of the exhaust.

Since then I have used seafoam many many times, and have even used it before an oil change in the crankcase (made relatively clean 3000 mile synthetic look like 10000 mile dino oil). I will continue to use, abuse, and recommend seafoam as long as it's available.

I used it to get my fuel gage working again...I guess it cleaned off the sulfur that fouls up the Vette fuel sensors....all I know is the gage now works. BTY why is it that of all the cars I have ever owned foreign and domestic is it that the only one with this fuel gage problem is the C5 vette...???? GM engineering strikes again..?? Another GM screw up ..??? And the President gives them $17B as a reward for producing garbage vehicles..!!!!!!!!!

I can tell you that the last time I foamed my coupe I pulled #1 plug prior to use and read it, used the foam as directed and the pulled the same plug again. The difference was very noticable, and I would infer from that that the effect on the combustion chamber MAY have
been the same.
Just my .02 worth.

 

I have never used seafoam but I can tell you that Techron works great. I have used it several times to clean my fuel filter and get my gas meter to work. It also cleans your fuel injectors also. You can buy it at any auto store.
