I was wondering if anybody has done the thing where you pull the vaccum line and fill it with sea foam which is supposed to get all the carbon off the valves and off the cylinder walls? If so which vaccum line on the 3.4 are you supposed to fill with the sea foam?

Thanks

I have done it. I pulled the big line going to the take booster. I believe it helps. Others will say no.

You will see the big black vacuum (½") line coming off of the brake booster. You want to use that hose. Also, you don't want to fill up the hose...yer gonna end up with a possible broke motor if you do it that way.

Just so you know..don't fill up the brake booster!

well then approx. how much should you put in it? Ive been told keep putting it in until it kills the motor then put the vaccum line back on and start it and drive it hard

Follow the manufacturer's instructions...


Performing a Sea Foam Engine Treatment on a Fuel Injected 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. (See notes about special situations such as the Vortex or Subaru H style engines.) If you are not certain, contact a certified technician.

Start the engine. For automatic transmissions, keep the car in PARK. For manual transmissions, put the car in neutral and apply the parking brake. SLOWLY POUR 1/3 to ½ can of Sea Foam Motor Treatment into the vacuum hose, while at the same time revving the engine to about 2000 RPMs. You will begin to see clouds of white exhaust from the tailpipes. When you have finished pouring, turn off the engine and let it sit for at least 10 minutes.

Now start the vehicle again. Drive it aggressively (but legally) for about 2 to 5 miles or until the white smoke is no longer being produced.

yep bam is right, that is exactly how you do it! I had to drive my T about 20 miles before the smoke was completely gone! It was the 1st time it had ever been done in 14 years, and about 80k miles! My grandpa and dad had it for its entire life, and most of the miles were in town, short distances
