Leaking DOC at welded seam. - Markos19 - 06-19-2023
So the dealer told me I have a leak at the welded seam of the DOC on a 2016 Peterbilt 389. They want ten thousand for a new one, which they also say they will inspect it and the DPF at the same time. Is it possible to just re-weld the canister at the seam at some other place? Does anyone know?

If it was mine I'd tig weld that bad boy shut.

Thank you for the reply. The dealer doesn’t even suggest this option but doesn’t say it won’t work either. I just need to find someone who can weld and has some familiarity with the after treatment system.

I'd try a local reputable exhaust shop like for cars, they may take it on especially if they make custom cats and stuff.

Great Suggestion, I have a 2002 CM570 and downpipe from turbo was $1000 special order from StealerShip’ I bought a down pipe in stock for $120 and brought it over to local muffler shop, 3 hrs later and $70 for labor.
Pipe Holding good and stong.
