Here's some interesting information on SeaFoaming over on LS1tech

Ok....as you pour SeaFoam into the brake booster line it immediately gets sucked up by the rear two runners....the front 6 cylinders get pretty much nothing. So you are cleaning the two rear cylinders. Also, fluid is heavy and gets sucked right through the engine and has no time to sit and soak inside the engine....it does nothing. Allot of that SeaFoam that gets poured into the brake booster line pools in the intake also and sits in the rear of the intake.

The smoke show is mainly that SeaFoam getting sucked up when the engine is started later on. I'd be willing to bet that if someone does a Brake Booster Line SeaFoam job, a whole can, then removes their intake BEFORE starting the engine, they will pour allot of SeaFoam onto the ground. Then reinstall it and start the engine......no smoke show. Fluids of any kind are not meant to go through an intake where AIR should be going through.
If you pour it too fast, the rear two cylinders almost stall the engine because they're getting drowned out by the liquid.

You also run the risk of getting too much SeaFoam into a cylinder and hydra-locking the engine...BYE-BYE engine.

They make products that do this job properly....Mopar Combustion Chamber Cleaner (MCCC) and GM has one also. They are FOAM.......so when you spray them into the FORWARD PCV vacuum port this foam travels with the incoming air from the TB and travels to ALL 8 cylinders, (((unlike using the brake booster line and the SeaFoam having to fight against that flow of incoming air))). Which is doesn't, it gets sucked up by the rear two cylinders only. This foam also expands as it sits, so it bloats itself throughout the intake, runners, heads and cylinders...touching all of the inside surfaces to eat away the build-up of crap inside. Fluids can't stick to walls and ceilings, they fall to the bottom from gravity. This foam sits and eats.

I did two full cans of SeaFoam in one week....until I popped my head up and said, "what the hell am I doing, this is a joke." The next week I did one can of MCCC, and it smoked more than both SeaFoam treatments combined.

SeaFoam is GREAT for the gas and to clean out the crankcase during an oil change.

I have been using SeaFoam for almost 14 years in my 1998 T/A. Every 3-4 months a put a full can into 1/8-1/4 of a tank of gas to clean my entire fuel system, from gas tank to filter to lines to injectors to valves. I personally don't use it for oil changes, I use GUNK engine flush at every oil change.
