My buddy used a screwdriver as a stethascope on my M30, and noticed that the loud ticking we thought was a calling for a valve adjustment, was actually my injectors! Is this normal? Is this a sign they should be replaced?

Thx,

I recently replaced the injectors in my m30. I will tell you if they removed the loud ticking when i start it up.

I fired it up with the design 3 19# ford injectors and it sounds like a sewing machine again! A bad injector can tick (loudly). Try running some seafoam through the gas tank, if that doesnt work you might want to replace them. If they are all making the same amount of noise, you might not have a problem.

I mean, I understand the whole theory behind pulling out the stethoscope, but I think you're making a lot harder than it needs to be.

Find someone with an autologic, recent modic/GT1 or other similar diagnostic tool and fire the injectors with it. Compare that sound to what you're hearing. Quick and easy; removes all guessing from the matter.

M30 valvetrain oil starvation is common and oft discussed around here.

well, i'm aware oil starvation is common... but i'm also aware valve adjustments are common. me and my buddy were planning one for quite some time when we realized the loudest noise in my engine bay was the injectors...
