0 Onyx610 Posted November 13, 2022 Share Posted November 13, 2022 (edited) Diffuser pipe, no I wouldn’t say that small leak is a reason it won’t “passive” regen. Will it complete a parked regen?

0 Onyx610 Posted November 13, 2022 Share Posted November 13, 2022 Passive regen occurs when the engine load and speed allow the temperature of the exhaust to get above like 650 or so. Also stay there long enough to burn off the soot. If you had a massive exhaust leak(s) then yes I could see that being the cause.

0 Onyx610 Posted November 13, 2022 Share Posted November 13, 2022 Has your driving style changed or location of where you typically are driving? You can seal that up pretty easily. Just get the aluminum gasket and two new clamps. One for the turbo and the one in the picture.

0 vinny933 Posted November 17, 2022 Author Share Posted November 17, 2022 Just an update i changed the 9 dollar gasket an put a new clamp on it . Dpf soot level stayed the same all day while paving. Went home on the turnpike and passive regen brought down soot level. Only way I saw leak was during a forced regen hope this helps someone 1 1 Quote Link to comment https://www.bigmacktrucks.com/topic/70697-exhaust-leak/#findComment-515335 Share on other sites More sharing options...
