This is only from my experience and how I set mine. Most of the problems I’ve had or seen others have is leaking injectors at the pintle/ seat area , most of any other issues stem from the leaking pintle seat , Otherwise not much goes wrong with them . When I’ve stripped them I have found soot impregnated on the seat and around the metering check valve. Being very careful I have managed to clean up the seat and get the injector to re seal when tested with a plate fitted to the metering acuator point. After really only ever seeing the same problem over the years I went to 85 inpd which is close to 9.5nm . I have had no problems with them set that way and even after strips the tips from a few set that way there is no visible damage or excessive wear . Seats were spotless. It’s just what I do and don’t necessarily recommend anyone else does it .
