What you Will Need: -2 Cans of
Sea Foam Motor Treatment -1+ ft of Small Vacuum Line
-Phillips Screwdriver
-Ventilated Area
STEP 1: GAS TANK According to Sea Foam this:
"Cleans fuel injectors, cleans carbon as you drive, lubricates upper cylinders, de-ices and removes moisture, stabilizes fuel" Dump 1 full can of Sea Foam into a full tank of gas.
STEP 2: CRANKCASE According to Sea Foam this:
"Frees sticky lifters and rings, increases R.P.M.'s vacuum and compression, cleans dirty parts, removes moisture, cleans PCV valve systems" Dump 1/2 can of Sea Foam into your crankcase (the hole on your valve cover where your oil goes. This is best done approx. 100 before an oil change.
STEP 3: ENGINE INTAKE According to Seafoam this:
"Cleans carbon build up, cleans intake valves and pistons, gives smoother idle, cleans catalytic converter odors, cures hesitations and pings, restores power and pickup " First, make sure your car is running at normal operating temperature and unscrew the cover covering the throttle cable. This is for keeping the revs up once you remove the vacuum line from the intake manifold.
Next, locate the brake booster vacuum line and loosen the cable clamp but don't remove the line yet. It is connected to the rear of the upper intake manifold. Located here:
Then, remove the brake booster vacuum line while a buddy or your third hand maintains a high rpm idle by pulling on the exposed throttle cable. With a (now 1/2 full) can of Sea Foam, take your "straw" (1+ ft of Small Vacuum Line) and place one end in your "drink" (Sea Foam). Place the other end just inside the opening of the nipple where the brake booster vacuum line was connected. You should see it sucking it through the "straw" and into your engine. Make sure this is a SLOW sucking over a minute or so not all at once!
Once you've sucked in the contents of the can, (you may start to see smoke come out the exhaust) shut off the engine. FYI: Cover the vacuum hole with your hand when trying to shut off the engine cuz it won't want to shut off with the leak! Hook the vacuum line up and replace the throttle cable cover.
Wait 10 minutes or more. Make sure ALL your doors are closed (house door included) cuz its SMOKE SCREEN TIME!!!!. Then start the car. I revved mine up a little during this period and then let it idle until the smoke was mostly gone. I then took it for a little spin on the freeway. Smoke was gone when I returned and it runs GREAT.
According to Sea Foam "Immediate Results: Smoother idle, increased R.P.M.'s better throttle response and improved performance."
