Anybody tried Seafoam cleaner???

[foghorn23]

After reading posts on this and other sites I'm anxious to know if anyone has used Seafoam cleaner in the intake, gas, and/or oil and their experiences with the product. I've read some really good things about this, (especially on the F**d board)

 

Ford Seafoam discussion

 

Anybody had any bad experences with seafoam (not Fords ) Thinking about using this in my truck, but would like to hear about how this works with the General's trucks.

I've used it for about three years and it seems about as good as anything I have used. It usually comes well recommended by most parts houses. It a little pricey but I also believe you get what you pay for most of the time.

I've used it in all 3 places and it works great. I wouldn't use anything else.

What is the cost of this stuff?

[superbee]

I pay $5.00 per 16oz can and I won't use anything else. This is the best in my book.

Hey guys...

 

Im nervous about pouring anything but gas into my tank or ingesting it up the vacuum hose...

 

Would doing something like this SEAFOAM void a warranty?

 

Anybody have any comments on this? thanks

[asepgrad98]

it should not void the warranty. I used a special "IV bottle" to put a can in the brake booster hose slowly over about 20 minutes.

Good stuff. Use the SeaFoam screw-top can through your booster vac line or PCV line. Then take the intake off, open the TB blade and spray SeaFoam Deep Creep into your intake. Let it sit for a while then go drive it. Works quite well!

I have never used it on my truck because i was affraid of it causing harm to the plastic intake manifold. Although i really wanted too. I have "been involded" with it on many vehicals and it made a HUGE difference!!! A 1988 izuzu trooper II, old 5.0L ford 150 (had amazing results, i mean ), a 5.0L single cab chevy truck, a '89 vette, 96 f150, early 90's mazda protage, among others.....

 

It says (from what i remember) use a 1/4 can in the oil, 1/4 can in the gas, and 1/2 the can in the vacum line from the brakes.

 

In my exprience, we used the whole can in the brake vacuum line, 1 guy pouring lightly, and 1 guy keeping engine alive via gas petal. There will be tonns of white smoke pouring out tail pipe!!!!!!!!!!!!!!(seafoam plus carbon). when can is gone, turn off motor for 5-10minutes, then start it up (might need slight gas petal to start) and drive the crap out of it untill white smoke is gone...

 

If you really needed it, you will feel a fairily big difference in engine operation!!!!!!!

Well I decided to go ahead and try the seafoam. Wow! What a smoke show. I'm not sure what it did but it did burn something off. I put about 8 oz through the PCV hose and let the truck sit for about 25 minutes. It took about 3 trys to get it started, and when it did...... THE SMOKE! I drove it hard for about 5-6 miles and the smoke finally quit. I poured the other 8 oz and another 16 oz bottle into the gas (about 3/4 full) and have driven the truck about 100 miles. Maybe it's my imagination, but it sure does feel more responsive. For $4.89 a bottle if for no other reason, the smoke show is worth it.

Can using SeaFoam damange seals or anythign like that? I'm considering using it on my 2000 Yukon with 67K miles, but I jsut want to make sure there won't be any drawbacks or damage by doing so.

 

Also, in addition to putting it in the gas tank (you just dump it in through the fill hole?), is the other best place to use it in the PCV? To do that, do you just pull out the PCV valve and dump it down in there?

 

If anyone could post some pictures on where to add it, please do.

 

What are the major benefits of using it -- does it just clear out carbon build-up or what?

 

Thanks!

Sroll down on this thread, it has pictures that show the intake tube you are wondering about.

Seafoam is very aggressive.

 

I would be careful using it.

 

My buddy put it in his 98.5 Dodge diesel and his dads 01 Dodge Diesel. Both of their injection pumps died within 2 days.

 

I would not recommend it in a diesel. I think it is a little too agressive.

 

I personally won't use it. Chevron Fuel System cleaner is good stuff, and I would recommend that.

Umm.... most GM parts are all clear-coated from the factory (even the intake parts) --- seafoam may strip this clearcot not good. perhaps something that is more specific to GM would be preferable-- even if the price is slightly higher.

Thanks GlennRMK, I had been wondering if/how well it worked in a diesel.
