Exhaust leak?

Exhaust leaks should be relatively easy to spot. Any leaks before the DPF should leave little black soot trails. On flex pipe, you will typically see it in between the ribs. I've never come across a leak after the DPF. Since you won't see any soot after the DPF, I'm not so sure what the best method would be.

 

2019 and it's still an issue. Finbyrd, I've had the same problem. 3 hours in traffic jam on NJ turnpike. After that I went to a fuel stop, but didn't even fuel up. Had dizziness, shakey hands, poor vision focus, and rapid heart beat. Reported it to fleet, took myself out of service, I was not going to drive like that. Parked auto-start to charge EPU flooded my cab with exhaust. I opened windows and eventually had to leave cab and go away for an hour. Came back and had to vent cab of fumes. It was bad. Finally got sent for repair check, after another few days, and guess what, flex pipe after turbo was damaged, right under cab air intake. (2019 International LT).

 

You would be dead before you know it with the gases that can get into the cab.

OOS that truck and have that leak fixed before you send it out again with a driver and load.

 

I just found the other day my mysterious leak that i was chasing it for a while and as a someone here mentioned it was the flex pipe right behing the turbo. Dang that pipe in vovlo was $800 no gasket no clamps

 

Is the flex made out of Gold ?

 

I have been asking my self same question. Ridiculous prices for those steel parts. I bet it cost them $7 in china but whatever i guess we have to pay

 

In the old days, before everything went proprietary, you could have just walked in to any parts store and bought a chunk of flex pipe and two clamps and it would have fit on half the trucks on the road.

 

You calling me old? Lol
We can still do that with our old stuff.
