Last valve adjustment was about 10k miles ago.
Air in the prechambers? Is that a result of worn injectors, or something else?
It sounds like I should start with fuel delivery & compression testing before chasing an air leak. I'll adjust the valves, individually crack injector lines, and do some research on injector replacement or rebuilding.
