    Default Bush mechanic's way to clean out cat converter ?

    I'm trying to occasionally help an acquaintance who is on his last legs financially.

    He has a 23 year old Camry which seems to have a clogged catalytic converter.

    I hate doing exhaust work as the bolts are usually frozen and I don't have a blowtorch. So I don't really want to unbolt the thing and knock out the centre of it. Thoughy that is on the cards.

    Does anyone know of a rough and ready barnyard mechanic's way to clean out a clogged cat converter, perhaps with some additive/cleaner I could pour down the intake whilst the engine is running ??

    Or perhaps disconnect the coil, pour something down whilst cranking the engine, THEN start the engine ??

    Haven't Googled it yet....thought I'd try some humans here......

    Cant advise on cleaning a cat, but for all rusted bolts/threads, i use ROST OFF. Should do the trick if you can leave it for a few hours, but the longer the better. A necessity in my workshop.

    Yeah, there is a way. Get a drill and put some holes in it. That'll free the flow.

    I doubt you can clean the cat. It works on a chemical reaction at high temperature. To reverse it I imagine you need either higher temperatures, some pretty gruesome reagents or both.

    Perhaps a s/h one is a better option?

    Don't try a spray-in carbon cleaner. They stuff converters.

    Either remove it and replace or ram a steel pipe through it and refit it

    The major problem with DIY cleaning is the safe handling and disposal of the toxic and hazardous waste products released by the cleaning process.

    What price do you put on your own health and looking after the environment ?

    With all due respect Rob. If your worried about the environment from a few cleaning products your better off not eatig a Hamburger once a week. Lots more environmental impact then a couple bottles of toxic waste into the air/waterways.

    Health issues. Sure, wear a mask and a flano and Im sure shell be right.

    Ah the "one person" doesn't cause many issues mindset.

    It's about the toxic by products retained by the CAT and rest assured there is more than just you disposing of oil and waste products in the sewer/ stormwater.

    No no. One person does make a difference. Its just that compared to whatever is in the chems/cat combo still wont touch one less hamburger a week both in environmental and health.

    Or

    Having a hamburger less a week is a lot more constructive that worrying about 1 cat and the cleaning process involved.

    We are on the same page.

    I don't eat commercially made hamburgers, nor do I dispose of toxic chemicals in a non environmental manner.

    Its all the same with all meats. The more concious meats actually take more land water feed etc. Conversation for another time.

    Whats the best method used to dispose of said products Rob?

    The cat?

    And the chems? Do local mechanics usually have a disposal system in place?

    Cat covert cleaning can be subcontracted. Similar to a mechanic using an engine rebuilder to hot wash the engine. Ie the task is given to a special business that has the necessary cleaning equipment and access to disposal facilities for the toxic remnants.

    Just as Macca's have steam cleaning contractors regularly detox and clean their kitchens and grease traps. The sludge is taken away in tank.

    However with a Cat it's probably cheaper and easier to replace it.

    I'm aware of the environmental impacts of cattle however the comparison between them and cleaning car components is not valid.

    We produce cattle to eat and survive. Not so with dumping toxic chemicals from cleaning vehicle components into the environment. this is entirely avoidable.

    Eating plants is a new concept of being envorimnental.

    Thanks for the info on the disposal. I never knew they could be renewed. I suposse with modern costs its cheaper to buy new? Or are the processes involved in cleaning just as expensive/wasteful?

    Unfortunatly theres really no such thing at the current rates of consumption.

    Remember how many people there are right now and how many there will be in 20 years.

    A conversation for another time.

    I replaced my Cat a month ago and the difference in fuel consumption and power was remarkable.

    An obvious statement.

    Around 300$ from memory on the xsara vts.

    Can you buy a second hand reco unit?

    It's a $10K fine in NSW for tampering with a cat. How much in Qld?

    I'd certainly never post on a public forum I was knocking the guts out of one.

    That style of eating has other environmental impacts by way of waste gasses and not to forget the antisocial effects on others.

    As much as I enjoy good repartee, you have "painted yourself into a corner" by initially endorsing unsound environmental practices and using the "whitewash" of cattle production will in no way justify any environmentally unsound practice.

    Just sayin'

    Im not saying that one is offset by the other.

    Im saying that its funny what things people consider environmental. Or the emphasis they put on subject type in comparrison.

    My suggestion doesn't aim at the rate of consumption, but at what is consumed. See below

    But as you say, another discussion for another day.

    Are you saying you aren't semi retired ?

    I'm sure a spot could be made available for you.

    There are many cheaper catalytic converters available as after market, that was the solution for our 91 Camry after it was stuffed in the paint/fuel silicon oil ??? contamination controversy years back.
