Which vacuum line do you use to suck stuff up?

Has anybody seen a noticeable benefit after putting Seafoam in? What benefit did you see?

[VileZambonie]

You won't notice much other than a smoke show. It can help break down the carbon build up if you're heavily carboned up. It is a good to do every once in a great while but as far as noticing any great driveability increase it won't happen. Where it can be most beneficial is if you are experiencing pinging or cold start stalls.

I'm getting both pinging, and cold start stalls heh. I'll try it and report back on any noticeable results. I am thinking of using a few other products besides seafoam, as well. You know, over time.

And yeah whoever said they are just leaving it in their oil... that's bad. You have to change the oil after you run it in your engine for... how long? Maybe 15 minutes?

[VileZambonie]

I recommend changing the oil after the treatment. GM top engine cleaner is good.

[Skunksmash]

But uh.. so you use 1/3 of the bottle in the engine oil, 1/3 in the gas tank, and you suck up the last 1/3 into the intake manifold? I never actually read the directions on the side of the bottle of seafoam.

[Layne]

Their instructions aren't very clear imo. But yea, that's the jist of it. Look them up on the tube too.

Doing the SeaFoam trick doesn't always produce desireable results.  After doing it to my S-10, carbon kept breaking loose and jamming between the EGR valve pintle and seat.  While the carbon removal is one of the desired results, taking the EGR valve off and cleaning it out sometimes more than once a day and several times a week isn't.  And, if the EGR valve would have been damaged and required replacement, it would be nearly $200 just for the part.  The truck was running fine before I did SeaFoam and I haven't seen any great benefit from using it.  It has been over 1 year and a couple of months since I had to remove the EGR valve to remove chunks of carbon...so hopefully that's over with.

[VileZambonie]

you know there is a programming update on your S-10 to prevent the EGR pintle from getting hung up right?

[70fastback]

Did not know that.  Post or PM me with more info if/when you have time.  Thanks!

[Skunksmash]

Any other programming updates for the rest of these trucks that you know of, Vile?

[VileZambonie]

Did not know that.  Post or PM me with more info if/when you have time.  Thanks!

Skunk he was referring to an S10

Yes there are some updates but may not be applicable to you

[Skunksmash]

That's interesting. I will call my local chevy dealer and see if they have any info on updates that may be applicable to me.

[Skunksmash]

Well, my local chevy dealer went out of business. So I called not one, but two other towns, and they are out of business too. Nice.
