I'm not sure how much city driving you do but that can carbon up the prechambers and injectors which does require more frequent purging/ cleaning than an engine doing mostly highway miles. I drive 90% highway...all the diesels I have owned never required one injector to be replaced. Yes they were louder when cold but that did not interfere with starting or cold idle or warmup. City driving is tough on any engine...diesel or gas and requires a lot more maintenance.. So purge often!

I get a bit of injector knock when cold but it goes away quickly.

I'm not burning oil and oil analysis came back A+. 168K+ miles, hoping for 200K with no issues.
