2017 GMC Sierra 5.3L Engine Tick

[Hexa Fox]

Hey guys, 

 

I have always received great feedback from this website. So lately I have noticed that my engine is making a 'ticking' noise. I know this is associated with the lifters failing. I have been trying to look around and figure out if I have something to worry about. I may take like a minute long video so you guys can hear for yourselves. However, there is definitely a 'ticking' present, I would almost describe it as as diesel knock. 

 

I already have a project car, so really do not want another project right now. The truck is still under warranty and need to get my paperwork to figure out what it says exactly. Is this something that GM would recognize as an issue and be under warranty? I am hoping at least part of this is in my head. The truck has just over 20,000 miles on it now. Any feedback and advice would be great. I also installed a catch can on it within the last year that some of you may remember.

 

I have seen people say to replace the entire lifter assembly the push rods with quality after market stuff and it resolves the issue entirely. However, since I am still under warranty I do not want to even consider anything like that right now. Anyone that has had luck with this is welcome to chime in though, it may be something I consider in the future. So hear is a video of a Mazda with the same clicking sound as my truck. My truck may not be as bad yet but this is definitely the sound it is making.

Mine ticks with 111,000 miles. Hard to say if it's strictly the lifters or the injectors but either way it doesn't bother me at all. That's pretty much how they are all will sound someday.

 

I mean you could take it into a dealership under warranty but if they find that the engine noise is normal you'll still end up eating the cost of the diag fee because they didn't fix anything.

Thanks Cam,

 

Mine is definitely not as bad as the video as of yet. However, like I said it sort of sounds more like a diesel engine than a gasoline on though lol. Another reason it is troubling is because mine barely has over 20,000 miles on it. 

 

Have you had good luck with yours did you delete the AFM through modification, a device like the Range or something else? The only thing I have done for my truck is install a catch can, which does seem to catch a lot of garbage.

post a sound clip, does it sound fast than the cam speed or  crank speed in revolution freq?   injector freq tick, spark jumping off a boot makes a ticking noise, high pressure fuel pump in the engine could have wear lash in the fuel pump rod to cam lobe?, 

 

correct me if i'm wrong but can HPT tuners disable each injector or spark plug in the scan tool, this might help tracking it down by going thru each cylinder to deactivate each one?
