Guessing I am not the only one   that got this message  UGH  sad they do not have a  real life and do stupid stuff like this .

 just wonder what my path needs to be  have  523,000 miles on this engine do not know history but so far we have replaced exhaust manifold mass air senor tube, turbo  so is it time for bottom end or engine swap , use a bout 1 gallon and half on 12,000 mile oil change  Thanks for input  

keep having a code of PO5Eb00  Cold start scr nox catalyst inlet temp too low   .This on a 2016 Mack MP8 505  started at 137350 miles this is the 5th time we now have 247665 miles  they can not seem to figure it out just wondering if any one else has had this code problem Thanks 

tossing this out there has harmonic balancer been replaced ? just wondering 

getting exhaust fumes from 2005 Chu 613 with 460 gray motor  had exhaust manifold replaced due to center section under turbo be cracked out new manifold with up graded studs and other stuff did all three sections   but still getting gassed anybody else had this problem ?
