Rawze's EGR tuneup - Hennessy - 09-14-2022
Just wanted to say thank you for posting those videos! Very helpful as I will be tackling that same set up in a few days. Questions that I may have.
When cleaning the parts, how did you clean the inside of the tubes? Carb/choke cleaner or carb/choke cleaner with a brush?
Do you recommend replacing all the sensors with new ones or are there sensors that i can just clean and get away with? What sensors would they be?
On the Peterbilt, you didn't clean the EGR Valve, but should I attempt to clean when doing the EGR Tuneup?
I have a Kenworth T660, ISX15 CM2350 with 757447 Miles. In frame was done at 650000 (ish) Miles with a new turbo and actuator about 4 months ago. Unplugged the (magic) plug just to get me back to Tennessee, so I can work on it. still derated at 25%, But no stop engine code, so I'm thankful.

* all new sensors if they are old.
* clean out the EGR valve if it has not likely been done in the last 400+k miles or so.
* carb/choke cleaner is fine for pipes.
* Check the circuit that runs thru the thermostat housing for the exhaust pressure sensor too while you are at it.
* Inspect and clean or replace the Doser injector while at it too.
* replace the DPF Delta-P sensor and inspect its cross-tubes + connecting joints for cracking / rubber cracked, etc.
* If it has been more than 250k miles, maybe pull the DPF and DOC filters, take pics of their faces, and send them to an OEM facility to have them baked, de-ashed, and flow tested .. then do a DPF replacement procedure in Insite software to go with it.
