Catalytic Converter Acid Wash

What about for the rest of us who are out of warranty?

 

If you have a converter that is plugged up there is a reason. If it's burnt no amount of any acid will fix it.

 

Water doesn't neutralize acid. You need a base to bring it back to a PH of 7. Use some baking soda.

 

On the Tundra forum that was linked, those using this solution for their cats heated the solution when soaking the cats in it. Did you do this at all?

 

8/80 in the US

This has got to be one of the greatest DIY of all time...

Agreed, get that pH over 7. I work with acids and bases every day at work. Metals will last in basic solution but if it's acidic it'll slowly eat 'em up. Sure it may dry now but every time you run the engine it'll have water in the exhaust to re-activate it.

 

I used a soapy solution....!

 

Yes i did, you can see the stove...!!

 

I know, I know, but some Times we hope something works,. in the other hand, if it ends up not working, I got a great know how on how to take all headers apart...

 

Don't do this!

Just use multiple water washes to remove the acid.

The baking soda could crystlize in the cat! Not sure if that is bad or not but It would be best not to chance it.

 

Well, everything is installed back on the truck. I'll be informing each 50 miles, or if the check engine comes back.....

 

Lol, you wash out the backing soda, you don't just leave it in there.

 

If I send you my boring cat can your chef turn into a gourmet dining experience?

I just picked up a pair of cats from a member for 250

 

When it recrystallizes you don't just wash it out anymore.

 

Lol, I wish I could get a couple of used ones...you are Lucky..!

 

I jumped on it when I saw it, plus got the guys assurance and guarantee that they will pass smog. Just gotta get some gaskets from Gadget@URD

 

First report @ 52.1 miles after acid wash:

Not check engine light has been set yet. Diagnostic tool reads that on board computer hasn't finished the catalityc converter monitoring.

At this time, no conclusions can be made, lets wait 50 more miles, or a check engine light, whatever comes first.

 

Damn I hope this works, I have the same problem. Good luck.

 

A magic potion!
