Hi,

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.

Suggestion:

you might have a collapsed lifter or a bent pushrod. if your engine has substantial miles on it you might just need your valves adjusted. a loose rocker arm will tick pretty loud. i would probably pull off the valve covers and pull the push rods make sure they arent bent and then re-adjust the rockers. something for the shadetree mechanic but if you only know how to put gas in and change the oil id take it to the pros.





Thanks for contacting Fixya.

2005 silverado 4x4 making a ticking noise when driving? Doesn't matter in 2 wheel or 4 wheel still does it from starting out until stopping.


The ticking may be caused by a torn or damaged front CV joint boot. Check each side of the axle assembly, right behind the tire for a damaged rubber boot. If the boot is damaged, you should see grease from the axle all over the front components.

Loud ticking noise, dash, passenger side very annoying


That ticking noise you hear is an HVAC actuator that has failed. It is a small motor with a plastic gear and the gear has stripped causing it not to open/close as it should.

I have 2005 Chevrolet Silverado and it just started making a ticking noise in the engine. The ticking noise gets faster and louder with higher revolutions.


I bought a used 05 Silverado and it had started to get a ticking noise. I had one of the lifters replaced as it was determined that it was sticking. A week later the oil pump went. Replaced the pump and have not had any issues since.

Ticking Noise in 01 Chevy Silverado 2500


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
