I listened to the engine.
A few things to note. One, my alternator bearings seem to be going out, so I’ll need to get that sorted soon.
Two, I about freaked out when I noticed a faint ticking noise, not the dreaded chain rattle but something else. After listening closer and putting my finger (carefully) on things to feel for vibrations, I can say with reasonable confidence it’s just injector tick, as it’s softer and more solenoid-like than lifter tick. And, yaknow, it’s coming from the injector area.
Also my valve cover gasket on the passenger side is leaking already… smh. It’s been less than 10k.
