I did this on my 97 Civic (170k miles). Car is neglected so it should have plenty of residue and gunk and what not in the engine.

Begin by parking the vehicle in a well- ventilated area. Locate a vacuum line that you are certain DISTRIBUTES EVENLY TO ALL CYLINDERS. On many vehicles, the easiest option is taking the vacuum line from your brake booster PCV.
DONE
Start the engine. For automatic transmissions, keep the car in PARK. For manual transmissions, put the car in neutral and apply the parking brake.
DONE
SLOWLY POUR 1/3 to ½ can of Sea Foam Motor Treatment into the vacuum hose(do not put any vacuum line into Sea Foam container to
draw liquid into engine), while at the same time revving the engine to about 2000 RPMs.
Well, it is hard to pour into that small hose (3/16" diameter I guess). So I put a little seafoam into the cap, and let the hose suck some sea foam from the cap. I repeated about 30 times to use 1/3 of the can. when I holding the cap with liquid under the hose, I was pulling the gas cable to rev the engine, I was to able to see the tachometer but I guess I was going from idle (750?) to over 2000.
You will begin to see clouds of white exhaust from the tailpipe. When you have finished pouring, turn off the engine and let it sit for at least 10 minutes.
I saw white smoke coming out. so far so good. I waited 10 minutes.
Now start the vehicle again. Drive it aggressively (but legally) for about five miles or until the white smoke is no longer being produced. Repeat Sea Foam treatment as necessary.
Well, here is the problem. I drove in 3rd gear at 3500 RPM for about 4-5 miles and I saw no smoke. What does that mean? I didn't do it correctly?
If you look on youtube you should see LOTS of smoke.
