4 times to dealer to try to find ticking

[pfmg]

2014 5.3 Crew bought new 41k right now

And no it is not the normal injector noise, service manager and techs have confirmed. after it warms up from a cold start for 5-10 minuites it starts a random ticking noise from the lower front of the engine. it goes away after fully warmed up. been to the dealer 4 times for the noise, just picked it up last night, and they just keep throwing parts at it. water pump, radiator, starter sheid clips or something.

 

and the noise is still there. I have even told them I think it is the vacuum pump. I just don't get how GM can afford to piss off customers and toss money at parts for nothing.

 

off to call the dealer again.

 

Then there is the crappy shifting tranny, I mention it every time, and they drive it and say its normal Truck would be gone if I could afford it.

It may be time to try a different dealership just to see if they have a mechanic that can locate the sound.

 

But I would be starting to get after them to tear into the engine. At least drop the pan and check the lower end.

 

If they can't find it on the outside then something is going on inside and I've seen bad bearing rings only make noise until they warm up and once they heat and expand they shut up.

I'd push for that vacuum pump as they sound like a lifter gone wrong sometimes.

Did they remove the belts and test once it starts making the noise? That would eliminate a lot of rotating parts.

I do not belive so, Its going back next Thurs, I see what they say.
