I've run seafoam in my cougar on numerous occasions, and have run 3 cans through my truck already.

It doesn't damage seals or anything, and just the other day I picked up a can of seafoam spray to clean my throttle body.

It seemed to do a real nice job cleaning my TB, and didn't make the engine bog down when I was using it like it does through the brake booster line. I didn't see much smoke either but my TB is really clean now.

 

Don't use anything except non-chlorinated brake cleaner to clean the TB.

 

seafoam spray is meant for cleaning the TB.

 

Dodge issued a TSB stating to use only brake cleaner. The SeaFoam folks would want us to use it for that, but so would the TB and carb cleaner makers.

 

anyone know of differences between the marvel mystery oil and seafoam? I've heard people on hear with success with both, just curious.

 

I can't imagine that seafoam is going to harm anything considering we pump it through our brake boosters, the only difference is it's point of entry.

 

You run the SeaFoam THROUGH your brake booster?

 

not the brake booster, the brake booster vacuum line. Have you used seafoam before?

 

Lot of good points being made on here. I will still concider taking it to my mechanic and having him do a fuel system cleaning being that it only costs a little over $100. Besides if anything goes wrong with any sensors he's good enough about putting in new ones for free! I go to school for automotive and the instructor told me the chemical(formula) they use hooks straight to the fuel line by-passing any gasoline

 

As I said earlier, I've used it many times and would NEVER tell anyone to "run it through the brake booster," as you advocate.
