Let me start off by saying I am not very knowledgeable when it comes to vehicles. I purchased a 2014 Silverado z71 crew cab hoping for a reliable truck that would last me well beyond when I pay it off. I figured I would come to this site to ask people that are much more knowledgeable than I about an issue I am having.

I own a 2014 Chevy Silverado 5.3 with after market exhaust. The exhaust was put on the truck by a previous owner. At idle, the truck seems loud (and not from the exhaust) standing on the side of the truck by the front doors. I am not sure "ticking" is the right word, but that's about all I can come up with. I have heard some people talk about the DI causing this, but my brother also has a 5.3 and mine is way louder than his. It is almost embarrassing how loud it is when people are standing around it at idle because they are constantly pointing it out. My question is: Is this the direct injection, or could I possibly have another issue (such as an exhaust leak)? I have attached a video for anyone that has the time to listen and provide feedback.

A big thank you to anyone that takes the time to provide feedback. I am looking forward to checking out this website in the future and increasing my "truck smarts." Thanks again.

 

Here is a link to the video of my truck: https://www.youtube.com/watch?v=zK643x41t4g&feature=youtu.be

Can you post a video? DI engines are a bit noisier at idle, but shouldn't be anywhere close to embarrassing! It could be an exhaust leak.

I hear the high pressure fuel pump in there. Doesn't sound abnormal in the video. Of course the phone is going to amplify all the small noises.

Hey guys. Can anyone give me a 2nd opinion on this “ticking”, I just bought the truck with 87,000 on it, dealership said it’s normal but man is it loud. Didn’t seem this loud standing at the dealership with a freeway right next to it. Read all up on the DI noise, just really second guessing my purchase lol. Thanks

not sure if you’ll ever see this but i just got mine with 102,000 miles and it sounds the exact same. Just curious to see if any progress was made finding out of it’s a problem and if it’s “fixable.”

Not certain if this is THE common cause of 5.3L ticking, but check your spark plug boots.  The 'ticking' noise may be spark arcing inside of a loose boot.   I've heard people mention this, and there's a few Youtube videos discussing it as well.

    • I imagine the cold winters up here with repeated short runs in town every day for those that live and work in town and given what I have come to learn on this forum with DI engines having fuel dilution issues, and if they don't change the oil until it says to but keep driving it for a while, I bet all that is just lovely on those finicky lifters. 
    • I just did some reading and Stabilitrak is more than a what I had originally thought. It is more of a vehicle control system to help the driver in precarious situations. I thought it was only the AWD system. Now I know. So I changed the title for this thread to AWD conversion to Z71 
    • Sounds like converting will be a bigger endeavor than I was thinking. This truck doesn't have 2Hi like the Suburban did. The Tahoe has 4Hi and 4Lo and a button to turn of traction control.   From what I understand the Stabilitrak uses open diff in the front and rear. When wheel speed is not the same the stabilitrak uses the ABS system to slowdown the spinning wheel(s) to transfer power to the slower non-spinning wheel(s). I thought the transfer case was open too. Being able to transfer power either more to front or rear depending on wheel spin. Maybe I miss understood some information with you saying and power transfer is 50-50. Thanks
    • My brother has a 2007 Avalanche with afm 5.3. It`s got 176,000 miles. Runs like a clock. Never been apart. Co worker has a 2010 Tahoe with afm 5.3. 230,000 miles. Never been apart. Runs like a clock. So, even though cyl deac is a weak spot, they can go the distance.   BUT, these engines had the oil changed regularly, AND had 5w30 as spec. I wonder if they would have lasted this far on 0w20? I`ll bet not.
    • I certainly could be wrong but I hear of pickups far newer than that 2007 cutoff which may not be going to the wrecker but are having engine work done and be that a reman engine or new engine or trying to repair the existing engine. Some of it would be design issues as per the cylinder deactivation system that GM has and one of those lifters wiping out the cam and the question of oil changes moving the needle or not on that whole mess, or in the case of Ford pickup engines that have the long timing chains and wearing them out and the roller followers and phasers and some of that certainly goes back to oil change intervals. But in those various cases the truck has all sorts of life left in it and so the unfortunate owner and may be original owner or used market owner that is pouring money into repairs so the truck is not seeing the salvage yard yet but damage is happening by infrequent oil changes. A friends son had bought a 2018 I think it is half ton GM and it had some sort of extended or used dealer warranty on it and of course the lifter issue bites and its rattling and so the dealer had to swallow the bill and was at least 7000.00 and I think they only replaced what they felt they had to replace so yeah, I can see that being a ticking time bomb in the not too distant future. Would frequent oil changes cure all these engineering "marvels", probably not but some engine designs have shown that they do much better if the oil is changed a lot more often then if the manufacturer service claims are followed. New trucks cost so much that there is an incentive to keep the existing truck on the road by repairing.
