I have an 05 Silverado 5.3L with 120,000 miles and I've noticed that there is a ticking noise when starting it cold. It goes away after letting it sit at idle for a few minutes. I'm guessing something to do with valves/lifters? Time to take it to the dealer? Help

Maybe time to search the forum? :)

 

There are plenty of topics about this. It could be the lifters, oil pump, oil pump gasket, etc. Or your engine is about to implode at any given moment.

 

Take it to a honest shop if you're still not sure.

Its piston slap. Just ignore it almost all of us get it. Or its a broken exhaust manifold bolt.

Thanks guys. I'll do some searching and probably schedule it to be looked at. Maybe it's time for a new truck!

My 2010 5.3 does this and has for the last 35k miles that i've owned it. It goes away after about 5 seconds maybe

Same here. My '09 5.3 did it. Started at around 60,000 miles, I got rid of the truck at 95,000 miles and it didn't cause any problems other than annoyance. Mine only did it in the morning when the motor was cold.

Mine 07 5.3 started around 65,000 miles. I just got rid of mine at 153,000 miles. It would do it for just a few seconds when started up in the morning. At first, it was just when it was colder, then as time went on, it was each morning. I also started using oil. Periodically, it would give me a puff of smoke out the exhaust like the old diesels when I fist started it up also. Hated to get rid of it, loved that truck, but it was time. Could not see putting the money into it. She was a very reliable truck for seven years.

+1 on this, the engine block is aluminum, the piston sleeve is steel. When the dis similar metals are cold, there is a "gap" in the tolerances, causing the noise @ startup.

The cold start "tick" (piston slap) has been the norm with these engines forever. There is nothing unusual about it and it will not hurt anything. Any dealership will tell you the same after charging a crazy amount of money.

 

OP, everything is fine, you have nothing to worry about.

120K? Not an issue. My '02 did this for years. It was over 280K when I sold it and still running fine. Normal sound for a pushrod engine.

PLEASE do not take your vehicle to the "stealership" for this problem, as said above, they will take your money, and then tell you it is "normal" for the LS engines.

 

I have piston slap in Sara (2001 Z28 40k original miles), and I have had it in my 2004 Chevrolet Tahoe (4.8L 107K original miles), and I have it in my 2013 Yukon Denali (23k original miles).

 

The "ticking" goes away in the first few minuets, and also keep in mind that the fuel injectors will tick when the engine is operating.

 

Hell, Sara sounds like a sewing machine when I first start her up. :)

I would also check you exhaust manifold gasket...my '06 aluminum block 5.3 does the same thing when cold. Ticks away until it warms up enough to close the gap.

I have learned to live with it as the truck has taken enough of my money in its 65,000 miles with me.

Thanks for all the advice guys. After some research on here and your comments I'm in agreement to not take it in. Thanks again! Hoping to put another 100,000 on it!!

      Video processing module location

      By twgraham · Posted

      Can someone tell me where the video processing module is in a 2023 Silverado? I'm getting conflicting results that it's in the front passenger area or the rear passenger area behind the seat.

      Missing thrust bearing? And oil selection

      By Chuck FB · Posted

      Yes I agree, its what amounts to free advertising to let people know about his UOA testing company, and not that there is anything wrong with that but certainly that is a motivator for putting out videos about the science of oil as well as other topics such as oil and air filtration etc. The interesting part I found with his last video is not only the physics behind the reason for the varying wear due to a diesels working torque range causing more bearing load and that higher viscosity oil is of benefit, it was also that the chemistry behind the GM Dexos 0W-20 and the Mobil Dexos licensed 0W-20 are far enough apart that its showing up with a difference in wear even though the two oils are matched in viscosity and in that comparison viscosity was not having the finger pointed at it.    There are a few youtubers out there or one anyway that I have watched a bit of who has gone through the pains of accessing various countries manuals for a certain engine platform and while in the US/Canada it may say use 0W-20 or what have you for some Toyota product, in some other countries it sings a very different tune for the very same engine with the typical traditional oil viscosity/ambient temperature charts to help choose which oil viscosity is correct for the conditions the vehicle will be used in and in some cases its taken an engine in a US manual that states only use 0W-20 as per warranty coverage and yet that same engine in certain other countries may have up to a 15W-40 etc oil option that meets the spec. Another words the guy who is driving through Death Valley or Phoenix and south weather at 120f is often being fed a line of bs by the US system that has forced vehicle companies to restrict the warranty to a specific low viscosity oil for anterior reasons as well as the long drain interval suggestions.    Thankfully youtube is free ( yet anyway ) for viewers to sift through information and of course comes with the good and the bad ( truth and lies ) and we can choose to turn off/not watch what a person finds is bs or just not interested in the topic.

      No doubt... But, as someone who doesn't pay for his services, but who has provided a few views/clicks on his Youtube platform, the data around the Mobil oil testing I think does have some value including to "freeloaders" like me.   A lot of what he's doing is likely showing the OE's work in their oil selection, something that many of us had kind of assumed was true all along, a good balance of both excellent protection and efficiency.

      Lake Speed is drumming up business for his company just by being in the spot-light so he has a vested interest in stoking the 0W-20 fire.  IMO

      summer road trips in the 2026 2500HD

      I knew when I bought my truck that it had off road hill decent or craw control or whatever they call it and rolled my eyes at that but it gets throw on with other options my truck has, I just never had a heads up if the highway speed regular cruise setting had anything to do with the brakes and that took me by surprise. If you've ever been to the top of Pikes Peak and watched those ahead of you on the way down with their brake lights on constantly, one can guess they are probably not gearing down or not enough anyway if their vehicle will allow and a good reason their is a brake check spot part way down where they use an infra red heat gun to check how hot ones brakes are front and rear.    Your right that once one gets out of the front range by Denver and I've not been on that stretch of 285 between Denver and Fairplay myself but I know its high and Fairplay at 10000 feet, Buena Vista at 8000, it drops a bit from there but then your going back up and over the 11000 pass and Durango is at 6500 . So yes your definitely right that 6500 and a lot higher is the theme of going anywhere out in that direction from Denver but hey, the down hill sections give fantastic fuel mileage !.    I don't even look at the fuel pumps for what premium costs here, since I live on a farm and up to this point get fuel delivered I am rarely in front of a fuel pump and when I am, I am often using card lock bulk fuel stations so it tells me what the price is AFTER I buy the fuel. Looking up on gas buddy and converting to US gallons but in Canadian dollars, regular on average of the prices listed was around 5.95 and premium is around 7.00 . That was one reason I did not go for the 6.2 half ton aside from its lack of carrying/towing if one was going by the rule of using premium fuel and until recently one could only buy regular farm gas if playing the few cents off game for farm dyed fuel for a "farm licensed pickup". But yes I hear you on the fuel price difference and like the diesel theme with it often being more expensive then gas it doesn't have quite the charm to it either as it once did although right now here for some reason the price of diesel has come down more so its now inline with the price of regular gas.
