Ticking and rumbling noise cones and goes at idle
SOURCE: ticking noises only when you start then goes away
Depended on the mileage and if the truck has been worked hard. It could be a few things, A worn out hydraulic lifter, a worn crank bearing, old engine oil that needs to be changed, or maybe a tired oil pump. Try using a stethoscope to narrow down where the ticking noise is loudest. From there you will have a better idea what the cause is. Take a look at the oil pressure, see if it takes to long in the morning for the oil pressure to start building. Every time you look at something different it will help bring you that much closer to the solution.

Sounds like lifters are bleeding down. Try doing an oil change with a thicker oil or even go synthetic. I use Lucas oil additive and it seems to work pretty good.

One thing you should get checked is the oil pressure.You could have an oil pump that is going out or getting weak.Also depending on how regular you are with your oil changes it is possible that you could have a sticky lifter.The oil pressure at idle should be 4 psi and 25-80 psi at 3k rpm.If it is less than 4 psi at idle do not do the 3k rpm.This is check with a warm engine.(normal operating temp).Hope this helps.Good luck.

Im having the same problem! No pop, just a hum, and my volume dial won't adjust. Like the actual dial isn't working. I can't use radio, cd, or aux. Silence SUCKS.
