I'd like to clean up carbon built up on inside of intake manifold on my daily driver. I thought that Seafoam works great but recently been researching and watching videos on youtube that prove otherwise. What could I use to clean inside of intake manifold/top of valves?

I don't think many of these products do much to be honest. I use seafoam if I have the intake off and put a few ounces in the intake ports but who is to say what it really does.Most carbon is not going to be removed no matter what with out a wire wheel or something along those lines.I cut the seafoam with chemtool.Water is free I have done that too but never noticed any difference.What is built up from so many miles doesn't clean up easy at all.
Pedal to the metal/carpet?! lol
Amsoil Powerfoam and a PEA rich Fuel system cleaner is about the best your gonna get.
Clean your MAF with MAF cleaner, Clean your TB with TB cleaner.
Spray Amsoil PF in while running, and dump Redline SL-1, Techron+ or Gumout Regane in the tank.
That's the most cleaning your going to be able to do short of taking the whole manifold off.

Theres only three that are easy to get and work. Redline fuel system cleaner, chevron techron, and gumout high mileage regane/ all in one
Water does a great job in de carbonizing the combustion chamber, It's an old trick and I've used it on the "Luv" machine and my old tractor a few times with good results.
Before you even start however, commit yourself to BEING VERY CAREFUL in how you do this as water in your combustion chamber will hydrolock your motor and ruin it. The key is a steady few drops through a vacuum line.
The way I do it is as follows.
Head to your local grocery store and purchase your favorite bottle of wine. Open and enjoy.
When wine has been consumed, rinse bottle well with clean water.
Run a hose or tube several feet long from vacuum connection on motor to an easy place where you can hold it without becoming impatient or developing a back ache.
Fill bottle with water.
With motor running, slowly and gently insert tube inside bottle of water holding the hose above the water level to the point it just starts to create enough of a "draw" to suck the water, (in mist or droplet form - DO NOT PUT TUBE IN WATER - MOTOR WILL BE KILLED AND GO TO MOTOR HEAVEN IF YOU DO THIS).
Keep an eye on temp gauge so you don't overheat the motor and listen carefully to the motor so you don't bog it down too much, (if it bogs too much, that means you're getting too much water mist in your combustion chamber).
Once again, be VERY careful when you do this, but it will work if done properly.

I have used all those products and never noticed one bit of improvement at all.And I use a whole bottle and put like a couple gallons of premium so the dose is high.I think E-85 would do more than any of them I use it 50 50 ratio.
I've seen Greeceguy's method used with a ball inflating needle on the hose to control the volume of water. Though, others never specified a wine bottle. I don't see why a 40oz Pabst bottle wouldn't be the obvious choice for this.
Anyway, if you have port fuel injection I would think any Techron or similar PEA based cleaner would do it. No gas additive will clean intake tract junk from the PCV or otherwise. Maybe wait until 3m three part fuel system kit is on slickdeals for 15 bucks or something (though I can't vouch for it's effectiveness).

In my opinion, way to much water at once, but a good example none the less, (and the guy sounds like Haji on "Johnny Quest)

Another example with more control over amount of water introduced into motor. (though during process, you can still enjoy the beverage of choice).

This "old trick" is time tested and known to work well for removing combustion chamber deposits and can also clean up the intake valves but for whatever reason mitmaks wants to clean out his intake manifold as well. I really can't think of any good reason for that but it's what he wants to do. The water won't work because the intake isn't hot enough to boil the water on contact.

There ya have it. PEA doesnt work and all of BITOG is wrong. Just run alky..

i had a jeep 2000 4.0 come into my shop from someone who lives a few blocks away from the shop he always used high test and drove like he was 95 yrs old it was knocking like a rod was going to break,, we sea foamed it through the throttle body and in the gas tank and then drove it like i stole it.. It ran rough was spitting and popping but after about 15 minutes it ran great and still does two years later.. Good stuff...Water would have cleaned a lot of the carbon also but you have to be careful.

How did you conclude your intake manifold has carbon? Its not like its inside the cylinder with all the heat and pressure. Throttle body cleaner.

I have bought all those products and not noticed any difference at all you want to waste your money go ahead that's all it is.Maybe the vehicles I had didn't need it but I don't buy them anymore.We as car people are excessive in many things that's probably why I have 500 dollars of detailing items.Its my opinion your wasting your money.If you have it like that go for it.
Sea foam,mmo,b12 chemtool,etc will all work when administered through a vacuum line.
I've sea foamed countless vehicles. Every single vehicle when driven by the owner got me a phone call asking what I did because the vehicle ran better.
On a low mileage vehicle I don't feel there's much to clean however if done helps keep responsiveness like new.
The only stuff I haven't used is the amsoil power foam and I really want to try the stuff because I've never heard a poor review.
As far as sea foam goes dribble in half a can at a time into a hot engine then take it for a high revving run.
Do the whole can,half a can at a time.

gasoline engine? why would you have carbon in your intake?
diesel engine? TDI? intake needs to be physically cleaned due to poor design of EGR.

Which doesn't affect performance, unlike the EGR system on some diesels.
