E46 M3 Engine Sound After Valve Adjustment

[MrFurryface]

so this is normal? i have a same E46 M3 2002. sounds exactly the same

[doomlord82]

@MrFurryface Yeah, perfectly normal. I can hear it on other owners' M3s.

[doomlord82]

@MrFurryface The ticking sound is coming from the fuel injectors. Get yourself a stethoscope and place it on the injector rail. It just means that those guys are clean.

Each engine valve bolt has to be torqued down to a spec number. if not clicking sounds occur.

[sunnyjason]

yes, my E46 330xi makes that injector sound too. I guess its normal. maybe try some seafoam.

Darn that doesn't sound right :( Did you have to re do it?

[doomlord82]

@simondalangpan Nah, it's just the injectors ticking. I've checked multiple times with a stethoscope.

[neverquit250]

my engine sounds the same.. This is a good sound right?

[doomlord82]

@neverquit250 Yes. I took a stethoscope to the injector rail, and all the ticking is coming from there.
