Engine Tick - 2015 GMC Sierra 5.3

[dalek77]

Wow, same issues with 2017 suburban. Two of my neighbors bought the same truck and no tick. Mine has it. Random, hear it on drivers side, heard in drive throughs at times, cruising on highway or driving slow around 1500 to 2k rpms. Brought it in 3 separate times. They finally said they're performing the below. We'll see how it goes, but I'm not optismistic.

My dealer refused to replace that part after I showed them a TSB that says to replace it. They said the TSB is not valid for my truck and opened up a TAC case with GM and they said there is currently no resolution.

The solution is switch to Ford, the number one selling truck in America for 475 years now. 
 
Cant wait to be out of my 16 rado I will never buy GM again. Had a Impala ss a few years ago and that was the biggest pos I ever owned, don’t know why I went back to Chevy. 
 
This engine tick is doing more harm under the covers than you could imagine. No other manufacturer has a ticking engine. 

Had an expedition for 10 yrs before this suburban. Had ticking, and corroded bubbling paint on hood and tailgate. Fuel pump went out twice. Oh, and the spark plugs broke off in head. Ford has its ****ups too. Can't win........

See way more 96-02 expedition and explorer than blazers and Tahoe’s. When’s the last time you saw a 92 Chevy truck? You don’t because they don’t last. Go to the working mans part of town you’ll see a 92 f series. 
 

New expeditions do look nice. They look like a suburban. Lol

I’ve probably had 50 small block Chevy engines from 150 HP to over 400. Never lost one, most of the good running ones had a tic.

what the hell are you smoking?  I live in the truck capital of the united states and there are 10 old Chevy trucks to ever 1 Ford and Dodge.  Sorry son, your argument don't hold shit around here.

That’s your particular area..sorry dad numbers don’t lie. F series best selling truck 97362 years now. Maybe the people in ur area can’t afford a new ford? That’s why I didn’t get one lol. 
 
Cruise by the mansions here and all f150s 
 
the man man who said he had 49 engines well none of them had afm which is the cause of the tick imo. 

Cruise by the Mansions there and they all have F150’s??

Fuel feed line did nothing to fix them problem....

[dalek77]

Have you guys ever tried a mechanics stethoscope and search for it?

I've tried.  Problem is the sound isn't present at idle.  Those engines make so many noises, it's hard to track things down.  Everything to me sounds like it's vibrating.  Vacuum pump, fuel line, etc.

 

I had the fuel feed pipe replaced to no avail.  I've settled on the fact that it is a rattle somewhere, because I can go over a bump and the noise stops for a while.  When the weather cools down a bit, I am going to tap around under the truck to try and locate things.  Also planning to dynamat the driver floor and firewall inside.

 

One thing I've read on these forums kinda makes sense as a culprit, and its the starter not fully retracting and bouncing off the flywheel.  This could be intermittent, and initiated/stopped with bumps.

I know sometimes in a fast food drive through, it's real loud. Ricochets off the building wall near drivers side. Think they'll mind if crawl under my truck next time to find the noise? Lol. I'll say my tranny blew.

I think my neighbors are beginning to wonder why I come home everyday and open the hood of my 1 year old truck.  Then crawl around under it while I have my 7 year old son rev the engine.
