TICKING VALVE ON 07 6.0 LTR CHEVY

SOURCE: Rapping/ticking sound in my 2001 Chevy tracker engine.

does it go tick tick tick tick and when it warms up it stops or goes quiet?
its your lifters not getting enough oil
when u change your oil it will stop till that oil gets worn out
you will have to replace the lifters or it can also be a slack oil pump not pumping oil around the engine like it should

SOURCE: Diagnosing a blower that began ticking and then stopped

yes i am havin the same trouble but i have had outside water come in through my fan motor there is a hole in the bottom of the fan houseing and the water comes through there i am now waiting for my fan to stop working all togather and then i will replace it but not before i find the water leak

if noise is higher pitched and coming in on valve time...(2wice for every revolution of motor..ie: faster)...then upper end pressure is down due to sludge, wear , lifter failure, valvespring failure,rocker stud lifting out of cylinder head (kinda common) cam bearings failing (very rare)..oil pump bypass stuck open..and a few other possibilities... respond and we will go over lower end sound (deeper ,slower) and see what identifies your issues .... miles

SOURCE: ticking noise and low oil pressure

DOES IT HAVE A LOT OF MILES ON IT OR MAY BE THE OIL PUMP IS IS GOING OUT? THERE IS A SPRING IN THE PUMP THAT IS A BYPASS FOR HOW HIGH PSI IT MAY HAVE BROKE THAT WILL GIVE YOU LOW PSI.

Sounds like a hydraulic camshaft lifter that drains down overnight and takes 30 sec to pump up with oil
