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

I have an 06 Silverado with 215k miles. Has the L33 Aluminum Block 5.3 in it. It runs great, has good power, but has an odd ticking/knocking noise. It doesn’t make the noise until it’s been running for about a minute so I don’t think it’s exhaust. I also do not think it’s a lifter because it sounds more lower end towards the rear of the engine. Has anyone had any experience with these L33s knocking? It has been making this noise for a while now and it’s very annoying/embarrassing. I’m not sure if oil has anything to do with it but I use penzoil 5w30 full syn. Let me know if you have any ideas, thanks.

Took my 2017 Chevy Silverado z71 to the dealer today . Engine was ticking on top end sounded like a lifter tick and slight deeper knock in bottom end . oil presure was all over the place would go from 65 psi to 25 psi at same rpm. I have 44,000 miles. Has anyone else had this issue? With the strike in play who know how long I will be without my truck.

Hey guys, I got a 2015 Silverado 5.3l. 138,250km. started ticking sometime last winter. Would happen instantly at start up and last about 5 minutes then would fade away. Sounded like a lifter. Took it to the dealer they said they couldn't hear it. Sound went away so left it. Fast forward to this winter and as Soon as the weather started to cool down I noticed the ticking again. Took it back to the dealer said they couldn't hear it again. I went and picked up my truck right at closing, soon as I fired her up the sound was there but everyone was gone so no one to hear it. I took a video. Next day I called the dealer, sent the video. Took like a week to get back to me. In the meantime I had taken videos pretty much every time I started it. Long story short after a brief fight with them about them trying to say it's normal etc they agreed that it sounded like a noise coming from the valve train. Left my truck with them, they called me said they had to change all lifters. Went to pick up my truck and on start up the sound is still there. This was a month ago. Sent more videos and a previous video from before they did the work and they are saying they can't hear it again. Took it in in person they agreed that there's an issue again and they will look at it. Now they are saying it's possible bad injector noise but they can't figure out which one ?. In the meantime I took it to another dealership they changed the vacuum pump. After that the sound changed. Now it's no longer at start up but once the truck has reached operating temperature and is more of a dull sound. Took it back to that same dealer who did the vacuum pump and they said valve train noise and deffo not injectors. But they won't work on it because the other dealer already did. They didn't change the VLOM or the cam. I had/have no check engine lights. Truck runs awesome. Sometimes rough idle. Any ideas what it could be? -
My engine is ticking and it seems to be getting louder. I read up and the Direct Injection ticking being noisy, but does this sound right? https://photos.app.goo.gl/ge3qqYU9YrzvPx3l2

I'm doing my best to isolate this ticking sound that is persistent, yet intermittent. Data so far: 2018 CC SLT 1500 6.2L 4WD Max Tow 19K miles, all stock Doesn't happen when motor is cold, much more prevalent when motor is warmed Doesn't happen when letting off throttle (only under application of throttle), can be heard in neutral, park, and in drive (not in reverse enough to tell--but it happens when transmission is not engaged) Sound follows steady or increasing RPM of motor Under light to medium load, noise is prevalent, under heavy acceleration it subsides (not because of engine noise) If I turn wheels hard left, the noise disappears, straighten wheels, it returns (like wheel is blocking noise from traveling) Sound only heard on driver side If I hit some oscillating bumps on the road, it can stop for a while before returning back (under varying loads as well) If left in tow/haul mode, at 2500 rpm under light load it can still be heard Ran 2 bottles of Red Line injector cleaner and it didn't eliminate/help noise The truck was silent until the 700 mile mark and I hit an expansion joint (nothing out of the ordinary) and the sound started and has remained ever since I've checked exhaust/manifold connectors and no sign of leaks (soot) I put a hollow aluminum rod (2 foot long) to the vacuum pump and did not hear any abnormal noises directly from the pump Obviously heard injector noises when put to the injectors; haven't had chance to stop on side of road when the sound disappears to run comparison tests Sometimes it'll run dead silent when driving down the road (after complete warm up) and power delivery doesn't change but noise comes back within a minute or two Sound heard in both V-8 and V-4 modes, and while in manual shift mode Use premium 91 gas ever since purchase (93 not available in Bay Area)--use Costco Top Tier fuel (high volume station) Oil changed with Mobil 0-20W Full Synthetic every 5K miles religiously and OEM filters (indicator usually states 37% remaining at around 5k miles) 90/10 Highway/City driving Any thoughts? My MPG is seems close to normal. Lifetime average of 17, most of my time driving is short city trips or long highway driving with a bed full of gear and a dirt bike. Some of the actions seem like it could be a noise related to the vacuum pump but the pump doesn't exhibit any noises itself. Sounds kind of like exhaust leak--exhaust seems to check out (no notable soot around connections or along piping that is visible). If it was something loose, I would think that even under deceleration (letting off throttle) would cause the noise to persist. It follows increasing RPM. I've checked around the footwell and haven't noiced any plugs missing or issues there. The fact that the sound is not there when cold or after some bumpy roads makes me think something else is up. Thoughts? Things to check? When it is quiet, this truck is wonderful. The ticking in the background that comes and goes is like a form of Chinese water torture. The fact that it does go away sometimes makes me even crazier as I know it could be better. When I bought it, it did not make this noise. Only after 700 miles of driving did it begin to tick tick tick away.
