Seafoam

So yesterday I put one third in the vac line and the rest in the gastank and let it sit for about 5 minutes like the directions say. I got NO smoke at all. I read that usually means that there is no carbon buildup but i know thats impossible..I have 104k on my car so there HAS to be some sort of buildup somewhere. But I did notice a difference with acceleration and idle..

As APynckel said; water/meth injection is a good idea. Can make a huge difference on forced induction applications especially once you've heatsoaked your intercooler.

Has anyone resolved symptoms of carbon build up with the Seafoam treatment in the IS250? I don't have any symptoms but believe this could be good preventative maintenance to perform.

You'll have to get the product into the air stream somehow. I saw mention of the" vacuum line" method of introducing the product into the engine perhaps that would work.

I'm aware of the benefits being introduced to the gas. I wouldn't use sea foam for this purpose with the exception of the left overs after being inserted via the vac line.
All being said, I'd like to hear real world experiences in curing symptoms of carbon build up.

I did this on my Gs recently. I poured half a bottle directly into the crankcase and the other half into the gas tank. Got the cops called on me because if the smoke lol. The idle was never rough so the only improvements i? Experienced are better gas mileage.

You pour it into the oil as well. It helps there as well. I wouldn't worry about "blow by".
Yes seafoam is a safe product however, there is a chance with higher mileage engines that you will have some seafoam blow by the rings and get back into the oil so I would advise that you do your full seafoam treatment a day or two before you are going to change your oil.

Poring it into your oil cleans your lower end and pouring it into the gas tank helps with the fuel system. I think these applications are well known and practiced since the introduction of seafoam. There are hundreds of fuel cleaners and hundred of snake oils meant to go into the oil hence an overall lack of concern for this use.
Again, has anyone used this for the purpose of Carbon Build up and what were your results?
Introduction into your vac line may only clean the upper part of the intake valve and the area that resides in the cylinder which makes me feel that this might not clean the exhaust valves in their entirety.

I would not expect Seafoam to do anything for exhaust valves, really. Then again, I have not heard of any complaints about carbon buildup on exhaust valves. Only intake valves.
