    3. Do you know how catalytic converters work and how do they get blocked?

    If you use an old grade engine oil it will poison the catalytic converter.
    The catalytic converter can also get blocked due to soot and carbon.
    Another way to block/damage it is by pouring something cold on a hot converter.

    To unblock it you have to run the engine at high speed for an extended period of time. It increases the temperature of the converter and breaks down the deposits.


    If you have bad sensors, your car runs rich, or there is some problem in the ignition system due to which unburnt fuel is entering the exhaust, you can clog your cat converter. Cat con runs very hot and when fuel enters there it burns and raises the temp even more which can melt the mesh.

    If you pour your cleaner liquid (or even regular engine oil or even water) on ANY PIECE OF HOT METAL it will produce the same white smoke. Now, does that mean that it is cleaning something? I dont think so.



    Lastly if you read the description here: LIQUI MOLY - Motor Oils, Additives, Car Care - Products - Catalytic-System Cleaner

    It says that the product is *quote* " for removing typical contamination and deposits found in the intake and combustion system"

    If you notice it does not say much about cleaning the cat converter (at least in the main description.)

    In addition it says "Dissolves and removes deposits and contaminants such as oil, resins, adhesive residues, etc. of the intake and combustion system."

    It also says "The high cleaning effect ensures a clean catalytic converter and reduces the exhaust emissions."

    There wont be any cleaning solution left by the time it reaches the cat con.
    In short they clean rest of the system and hope that if rest of the system works well cat con wont get clogged.
    White smoke it the part of the cleaning process, it might not have renewed the cat but surely have its impact thereon.

    Your remarks are valuable indeed.

    I am not sure about that. Probably won't help if it is too much clogged.

    It is usually recommended to not drive cars for short distances because the cat won't reach the desired temperatures. It makes it more likely to get clogged.

    So it is better to prevent clogging than to repair it.

    There is a thing called italian tune-up. (google for more info)
    You basically run a warmed up car at high rpm (~4000+) for 10-15 minutes, often reaching the redline.
    It is supposed to clean the carbon deposits in the combustion chamber and the exhaust system.
    Try to do it around the time you do an oil change.
    Please quote or tag me if you want me to reply as I dont check forums often.

    dont waste that much money

    remove the cat ...but 2 bottles of battery acid .. used proper gloves and put them in cat... keep both end of pipes closed with help any shopping paper ..and let it be in there for 3 mints

    remove it and everything inside will be out .......

    all this wont cost more then 300 rupees including labour

    wash it before fitting back and avoid direct contact with acid ........... have done it on many cars and it works great ...
