    HOW TO: Clean Carbon Deposits w/SeaFoam

    ANyways.. I just wanted to let you guys know this stuff absolutely works and dont bother spending $70 for carbon deposit cleaning when you can do it yourself

    SeaFoam available at Napa auto parts, price $6 a can. How to use it: feed slowly into one of the vacuam line going into the cylinders (I used the PCV line). Use about 1/2 to 3/4 of the bottle..at about the 1/2 pint mark you will start seeing smoke coming out of your tailpipes at idle. Once fluid has been sucked into the engine. Turn off engine for about 1-3 hours, the longer the better. Start the engine and begin the revs... watch the GIGANTIC smoke cloud and the birds fall from the sky choking on carbon

    Take the car out for a spin, and WOT the baby on the highway to clear out any leftover carbon from the engine. Immediate results felt, better accelration, smoother idle, and slightly better gas mileage this morning to work. All in all a wonderful product.

    Hope this helps anyone who was thinking of cleaning the internals of their engine.


    note i did not do this DIY... if u try it and anything bad happens u can't blame me :) do at ur own risk

    I did it on a motor that is at 189xxx and it is running fine.
    You will want to use your own judgement on this one as you could potentially burn up and blow out all the carbon and crap that is sealing any little nicks or pitholes in your motor.
    You pour 1/3 into gas, 1/3 into the valve cover (like you are filling your oil), and 1/3 feed into the PCV line (pull it from the valve cover)

    But be sure to change your oil immediately after dumping it into the valve cover.

    i asked one of the guys at napa about putting it in the valve cover and he said it will be fine, its just best to change the oil within a few hundred miles.

    what about other type of carbon cleaner? I've got a bottle of motormaster's last time, wonder if I can use this here.
