The information to the editing was perfect great job

[@jdubya54]

Excellent teacher. I dont have the problem but I like to learn proactively too. Thanks for the video

[@lizirizarry1793]

Loved the way you presented the entire video! Thank you for the information!!!

[@mikejerrett7354]

The vacuum trick was cool awesome 😊

Put my truck in the ditch a few days ago. Smelled exhaust today while driving, time to do this test, thanks.

[@imagerymatters]

Wow, such great info. Thank you

[@DANNYN224]

That’s a nice trick instead of using your hands and feeling for a leak potentially burning them

1A is the best...them and Chrisfix got me right!

[@imakedookie]

since spraying soapy water all over my exhaust to locate the exhaust leak, i smell a dish-detergent kind of smell mixed with exhaust now when its defrosting, any way you guys could do a follow up video for that?

[@1AAuto]

+@imakedookie We do not have a video for this repair right now, but we'll keep this request in mind for a future video! 1aau.to/m/Shop-1AAuto-c

On my 2010 Outback, it was the "variable valve lift diagnosis oil pressure switch" (one on each side) that was leaking oil. Smelled like propane until I replaced it.

[@nightfangs2910]

Can you spray the pipe down with an undercoat?? to get it to last longer in the rust belt like me in Massachusetts

[@handycrowd]

Perfect! Easy and logical. Nice 'trick' with the vacuum. See exactly the same problem on Honda CRVs, the compressed wire mesh gaskets rot out all the time 🙂

Love the shop vac trick

[@melissa8696]

This was awesome because I just had my transmission replaced and it came back with a toxic smell no one could smell except me. I was getting sick, headaches, having episodes of piercing pain in my face and eyeballs and headaches were so severe I couldnt funtion. I went without a car for so long I was scared I d lse my jobs. and finally at times others started to smell it here and there and one day after the 3rd time of Ford picking it up I didnt then I did. Now I have appt to take it to someone else cause I no longer trust Ford who swears even after one guy got sick driving it they swear there is no smell or anything. So we will see and this helps me know IT ISNT JUST ME.. Thank you.

[@HotRod-wv4vm]

can you do the shopvac process to the engine bay?

[@enriquelopez9124]

Awesome informatio & tutorial.

[@therealfrickenchicken]

I just had a brand new high quality exhaust put on my car and after a few weeks of driving noticed a gas smell in the car when turning on heat or ac. The car is almost 16 years old, but it wasn’t long after the new exhaust was put on, so it’s hard to say if it’s a coolant leak or something with the exhaust. Do you have any tips? I highly doubt there would be any holes in a brand new exhaust.

I have toyota corolla 2009. I do feel like there is some fumes getting inside the cabin some how. It is odorless. I don't smell anything but I feel the allergy. I started dry caughing. some skin irritation and throat irritation. I believe it is somehting. Went to mechanic, he checked said everything is fine. Changed the cabin filter but still i feel it. It all started after some one hit my rear bumper on the driver side. Any advice please.

[@robertdiehl9003]

I am assuming that a leak in exhaust will cause Check engine light....

[@user-bc1kp1sl2e]

What if you only smell exhaust fumes on idle without recirculation of ac on?

[@Sourpusscandy]

My problem with the exhaust smell coming in via defroster, that operation opens the plenum or whatever part that diverts the air, from what I normally run “recirculate in the cabin” to “use air from outside” and I smell exhaust, skunk, whatever the heck pooopersville from outside. Does this not go through the cabin air filter? Gah! I’m always switching the defrost on and then off and closing the outside air to recirc.

[@Sourpusscandy]

I don’t smell exhaust when there’s no cars/trucks running in front of me.

[@simondurcov]

is it okay if i only smell it on the other ones ? i dont smell it on defrost

[@llisagomez5706]

What a woman!!!❤❤❤❤

[@willsrestorations]

Anti-seize never goes on the female threads, every time I see a video about automotive does somebody doing something really stupid. That anti-seize goes on the threads of the O2 sensor only

[@abdoalhussein]

Catalytic converter is rusted but the bolts are not🤔

[@lilllwizzzle]

Nice!

[@PLATINUM2U]

What if you smell exhaust when the vehicle is floored on the highway

[@1AAuto]

+@PorcheGT3 We wouldn't be able to diagnose an issue like that here, you may want to have a local mechanic take a look at it. Thanks for checking us out! 1aau.to/m/Shop-1AAuto-c

[@chippy_crumb]

Heck yeah, lady mechanics! I once took my car to a shop ran by just 5 women. Super awesome :D

[@physicsfaith]

Now all I need is a car lift...

Oxygen sensor

[@melissa8696]

I wish you would wear a mask while doing these tests though for real.
