How To Find An Exhaust Leak With Smoke Machine

[@BarboursAutoHelp]

By the way... I know, I know... I didn't need a smoke machine to find this leak. I've actually known about this leak for a few years now. It's a demonstration video folks. Hope it helps!

[@oshkoshbegone]

I laughed out loud at work when you showed the hole... I get it was for demonstration purposes but it was funny as hell.

[@BarboursAutoHelp]

Yes, very funny but by accident. I should have presented it a little differently. But there it is. lol

[@sextingwithdolphins]

I exploded with laughter 🤣🤣🤣

[@uranusneptun5239]

Good thing mentioning the holes that are there by design!

[@autolinepro]

Thanks for the awesome video Keith! We hope you are loving our smoke machine! We really appreciate your support.

[@BarboursAutoHelp]

It's fantastic. Thank you.

I'm about to buy this right now...does it come with the adapter to fit a nice tight fit to the exhaust?

[@BarboursAutoHelp]

They have what you need. Website is easy to navigate through to find what you need.

I used a shop vac w soapy water. I saw bubbles from the front cat in my 2.4 2001 taco. That means the cat is toast right?

[@macknumber9]

I just bought this to try and pinpoint a tiny exhaust leak that I found with the shopvac+soapy water method and i was surised to see that the smoke was not visible out of these pinhole/hairline cracks...i guess this is better for detecting leaks that are not hairline/pinhole

[@howabout2138]

For super tiny cracks you need more pressure, for big you need a lot of smoke

I have 2010gmc sierra 5.3 want to buy a smoke machine. Where would I attach it to engine to check evap leaks

[@blackfriendlygiant]

Silly question but I have a smoke machine used for a party a few years back. I'm not a mechanic and I'm trying to find a leak in my exhaust. Would this be useful? Will using a water based smoke fkuid it damage the engine?

[@TravMan923]

I would imagine that would work fine!

[@gz617]

I need to diagnose a leak with my catted headers around that exhaust manifold and where it meets the midpipe. Is that stuff safe for a catalytic converter?

[@BarboursAutoHelp]

The stuff sold by AutoLine Pro is. The stuff most machines use is.

[@macknumber9]

How do you repair a catalytic converter leak? Do you need to take to muffler shop and have heat shield cut off and then rewelded back together after the leak is repaired?

[@BarboursAutoHelp]

Probably just replace it.

[@macknumber9]

@BarboursAutoHelp wouldn't it be much more cost effective to just have the heat shield cut off...leak repaired and then heat shield welded back? Can't be that labor extensive

[@BarboursAutoHelp]

@macknumber9 the trick is doing it without damaging the catalyst.

[@billwolfe3579]

I am wondering, willl the smoke go through the cat to show a leak in front of it?

[@BarboursAutoHelp]

Yes. If the cats are not hot they don’t work.

[@antoniogonzales3030]

Is there a chance the smoke might damage or affect some of the sensors?

[@BarboursAutoHelp]

I've never had an issue and it's recommended by manufacturers to use a smoke machine to diagnose lean codes. So, I doubt it.

[@markholyoak9790]

Great video thanks for making it

[@BarboursAutoHelp]

No prob.

[@xnitro6794]

have the same machine but smoke doesnt go through the exhaust system?

[@BarboursAutoHelp]

It should. What kind of vehicle are you working on?
