I've only been burned 1 time on both a cat and muffler being plugged. The cat broke loose, and some of it got into the transverse muffler. Of course you could suspect all day, but there was no way of knowing w/o replacing the cat and front pipe assembly 1st. I found that out after the fact. In other words, that car needed an entire new system front to rear, and unfortunately, it was a tough sell. ( In case you're wondering, it was on a 02 Camaro w the 3. 8. )

Thats amazing that reduced 80% of the motors performance. How many miles are on that cat? thax. I took out my o2 sensor on 4. 3 blazer today and started the motor and it reved smooth and powerfully. i most definitly have a clogged cat also. with 02 in it barely runs at all about 20% power. thax for sharing

Nice follow up. One of the advanges of watching older videos you can sometimes find follow up videos right away. Ive been really eating up your vodeos over the last month. You're like a perfect pair with my Scanner Danner watching. Just wanted to say thanks and you're a real credit to your profession.

The
Light is so thiin in matter that it will pass through any where. The fact that your light was barely visible sais it all.
For a good visual indication you can poor liquid in and note the time it takes to come out.
Thanks for your videos Eric

Just a little info on this. These GM cats, with the double wall tubing in front of it, have an issue where the insulation between the two tubes breaks down and clogs the cat. Seems like there's no way of preventing this from happening.

I've heard these things can be cleaned quite well. 8 hours in mineral spirits and 8 hours in Tide with water. Then rinse, blow out, and dry in low heat. Then just weld it back on. The catalyst is not effected by detergent or solvent.

Throw back to some of the early years when we had to repair/rebuild GM cats, the flat ones where you removed them and popped the plug and dumped out the old pellets and poured in new ones and reinstalled. How many here did that?

Hey Eric thanks again for doing these vids for guys like me trying to learn. One question - would the downstream o2 sensor give you any indication for this? Maybe even something you could use for this diagnosis? Thanks.

That cat was plugged! I seen a guy in town one time hammering that cone out of his converter with a long screw driver. Bang bang boom, Pieces falling out everywhere. A little too obvious what was going on there.
