Injector noise

I have a 03 F150 5.4 that has ocassional noisey injectors on the passenger side. It happens mostly right after a cold start. It runs great though. Ford says this is normal. Is anybody else having this problem?

Thnks

live with it, injectors are noisy in the modular motors. Don't worry about it.

Modular just means the family of motors, the 4.6, 5.4 and 6.8.

Every 4.6 I have every owned, I've owned 5 4.6 equipped vehicles, makes the ticking injector noise.

The 4.6 is a great motor, I have had cadillac owners ride with me in the truck and say wow this truck runs smoother than my northstar v8, and they are totally right.
