4.9 starting to tick
 

I change my oil regularly and treat the engine better than I treat myself, but its starting to tick, it started a while ago but very difficult to hear, if you didn't hear it everyday you wouldn't notice the tick but now its gettin louder what do I do?

First locate the source of the tic. Use a piece of rubber hose , a screwdriver or a stethoscope. Is it valves, lifters, rockers, bearings, rods, or an accessory making the noise.
