It was inhibiting the movement of the valve piston. Noticed increase in Nox and found culprit.
Remedy, Good fuel treat used constantly, high quality oil that doesn't shear or volatize easily, and periodic cleaning with a safe,effective cleaner is highly recommended.
Maybe that 10 year warranty will come in handy. I'm the most anal engine guy you'll ever meet, no wonder people are freaking out when this happens.
Total miles 50000.
