Only have 13k miles on my 5.3 and at idle I hear a slight click/tick from what sounds like the oil pan area. It’s definitely the bottom rear of the motor. It ticks about every second like a clock. Anybody have any knowledge of this? Thanks,

High pressure fuel pump for the direct injection. It’s actually sound deadened quite a bit.
