Lifter or Injector tap?

[Rickyace09]

Dropped my truck off at the dealer for a lifter tap noise that it started doing at 30% oil life. Only on cold starts and usually happens about 5 minutes are start up or after oil pressure picks up. Goes away after engine is warm. Dealer is telling me it’s a normal injector tap.

I was told the same thing with my 15 Sierra. Dealer said it’s the injectors making the noise and nothing to worry about. Needless to say I’ve been keeping a close eye on things ever since.

Lifter tick and ticking from the high pressure fuel pump are very similar. At least to my ears..

 

The dealer just didn't want to tell you that the problem isn't bad enough to fix yet.
