140,000 Miles! Seafoam Questions

[Gitingrdone]

I would like to get some input about the product "seafoam" and its results. I just reached 140K and want to know if it will give me back what I might have lost along the way. What will it help or hurt. I saw videos of "DV2000NJ"s truck on youtube. I want to know if all of that smoke is worth something.

it is supposed to help get out all the carbon from the engine to allow it to run better. I have put seafoam in the gas tank for the last 15 fillups on the car (1993 Cavalier with 185,000 miles), and I have noticed a less rough idle, but I have yet to inject it into the lines or the intake...

Personally, I didn't see a huge improvement, but I didn't lose anything by any means.

You're from Gville and I assume you're a Gator fan, so you are excused by me. I wanted to do seafoam, but I have yet to do it because I didn't find enough information (even in that thread) to make me feel comfortable enough to do it to my truck.

I did it for kicks at around 55k miles. It seems to have helped with the rough idle a little bit. We dumped it right into the throttle body on a '93 Silverado with a 350 and ~215,000 miles. It was a night and day difference. Obviously results won't be typical, but I can say I have experienced first hand that it can and does work. For $6.50, I'd do it.

Yeah, it helps somethings.... Just make sure you don't do it in the carport or inside a building...... If you do you will find out what I am talking about. Find the vacuum source closest to the throttle blade. Remove hose and plug it off. Put long hose on that source and open can. Crank engine. Allow to idle and slowly let it draw down on the cans contents. Keep engine running for half of the bottle then allow it to GULP the rest of the can and stall the engine (allow the engine to die). Let it sit about 15 minutes and crank it up and you will see all that carbon..........

 

However I am not sure about long term multiple uses on the catalytic converters....... It has to pass threw them to get to the end of the pipe so I wonder. But I have done it to a many vehicles that had an IDLE problem and it will cure it right up.

 

Also, here is a Ford thing.... 4.6 2valve with a Aluminum intake has a groove below the plenum that will become lodged with sludge from the egr. Quite the power robber/idle issues....

Edit: I sell it by the case to a couple of used car dealerships....... Every car gets a can, ran in it same method...

the most entertaining part is leaving a smoke screen up and down the block, i have yet to do it to a car...but the video of the volvo station wagon is great
