How to clean inside of ls6 intake manifold??

I remember seeing a thread about it. Some one posted a paper/document from GM on how to clean it. So if some one has it can they post? Please.

Seafoam. Goes into the vacuum line... smokes like a mf afterwards. (for about 10 mins). Search for tons of threads on it.

Like Todd said, I would look up Seafoam. There is a good write-up on how to do it. i believe the "Seafoam Deep Creep" is what works well in the intake manifold to get some of the grime off and it is petroleum based so no harm to the engine, but you want to change your oil not too long after you do it, good luck.

you're on the right track. But use Deep Creep made by Seafoam. Spray it liberally into the intake manifold let it sit for about 20 mins.
