Has anyone tried the seafoam into PCV method for carbon cleaning?...

[drewgold]

Curious if anyone else has tried carbon cleaning following this DIY:

Thinking of giving it a go, are there any drawbacks to this method?

I'd also like to know!! Same steps for a 2.7?

No I didn't rereadr that thread, but if I remember correctly, you would still have to do a carbon cleaning. After the cleaning it can help prevent some of it, also it will only hit the front of the valves. If you want to do it, go ahead, but you will still come to the enevitable.

That actually works like a champ. I personally have done this about 25x on my vehicles, customers and some friends with no problems yet. Two things I typically do differently than the write-up is replace the plugs after the service is complete and the engine has cooled below 100 deg F and I stall the engine until it shuts off by flooding -flooding should only be done at idle- let the Seafoam soak for 10- 15 then restart and complete a 10-15 min highway run.

Plug replacement is not mandatory only recommended as maintenance. I prefer the stalling method because it really saturates the combustion chamber and lets the Seafoam penetrate and loosen the carbon deposits.

I directly shoot sea foam over all intake or exhaust valves when I pull the intake or exhaust manifold directly (red straw) and soak the piss outta them. As well, they soak for a minimum of hours as the car is apart and not driven. I'm not talking a little squirt, but soaking every angle of each valve including the stem.

Before treatments the exhaust valves are (used to be) ~caked with carbon build up and even the intake valves would be dirty, After the treatment, and given say 4-6 months, when I pull the manifold(s) for what ever reason they are now........extremely clean and ALL carbon deposits are gone. As in looks like a ~new motor. All the caking, all the layering, is gone.

Keep in mine it's the "first time" that really helps as that is when you have years and years of carbon build up.

As far as squirting into the intake, tb butterfly, etc....just forget about in. You need to physically spray the valves...not shoot a can through the intake manifold.

I also have one of these in my toolbox and works well. Its quick, don't have to take much apart, well on most cars and will achieve the same end result. Granted it is hella expensive but if you have access to one or are in the industry I recommend it. And of course you can get a more economical set up if you go this route. It def will pay for itself... eventually.
