My wife wants me to seafoam her 04 Impala SS. I've done this with my 99 Acura TL, but I'm not familiar with the Impala engine. I want to run it through the intake but where do I run it? I'm assuming there's a specific vacuum line/port to use, but where is it? Any help is much appreciated.

buy the can that goes in the gas tank. pour it in, fill tank, done.

You might try the brake booster vacuum line

Make sure you put a new fuel filter on afterwards - I learned the hard way...

Seafoam is good and effective. However, if the car is running well, don't mess with it. Don't fix something that is not broken .

I know it goes into the gas tank but that's not what I'm looking for. I want to run it through the intake system. You know, white smoke from the tail pipes and all that junk. The car runs fine, but there's no harm in cleaning things out. It has 68K miles on it.

You're probably trying to clean something that is not dirty.
