Thanks for sharing Mason, nice job ! Too bad he didn’t do oil sampling he would have picked up excess fuel dilution early on maybe have prevented a failure! Just saying sometimes it helps! Thanks for sharing hope all is going well! Take care now have a good week bud !👍

Just had one a Cummins V16 cylinders .
Smoking on right hand bank .
But funny thing it idles pretty decent.
Customer put 8 injectors on it still smoking .
We show up ck valve lash and all exhaust were tight (clue #1) reset lash still smoking .
Pulled injectors and air tested cylinder and would not hold air ,it was coming out the exhuast.
Pulled 1 head and the exhuast valve had sunk into the head and the valve seat was gone .
Today's young techs have a hard time diagnose a mechanical failure like the one your showing
Boils down to ,do you know the root cause ?
