Loud Tapping Noise:2009 Silverado


Asked by Mar 18, 2011 at 04:36 PM about the 2009 Chevrolet Silverado 1500

Question type: Maintenance & Repair

Tapping noise is noticable when at stop light, when engine is turned on and when im parking. I notice the noise a few days oil change at goodyear. My truck has been with the GMC since 3/15/2011, and still they can't find what is causing the noise. With my permission, they want to get inside my engine for powertrain defection. My concern is, if its not defected i have to pay $2600.00 plus more depending on the problem. Now, i was told it could that my pistons could need adjustment because of the noise. Or it could be at time of oil change. Now with limited knowledge and experience i was advise by goodyear to take it back to the dealership or local owned auto shop because its an internal issue. Please help me. Thank you

sounds like they are right. it would seem to me that its an internal issue with the engine. it should be under warranty so just take it back to the dealer

my uncles 2005 1500 with what i belive is the same engine as yours... 5.3L is having similar problems, also happnd right after an oil change but he was a bit over on it, his problem is the lifters making noise and weve done some reaserch and it seems many others are having the same problem, always remember a tapping/ ticking is always more than likly going to be a lifter or rocker. if it were a deeper noise or a knock your be in much deeper trouble. i belive chase is right it should be under waranty but if not any work done by the dealer will be far from cheap expecialy when your geting inside the motor. if its not under waranty i would purchase some LUCAS oil aditive or even lucas break in oil and add it to your oil if that dosnt take care of it its up too you from there. also SEA FOAM makes a good product but i have no expiriance with running it in my oil

... and your pistons are fine if its intearnal it is either a lifter or simply a loose rocker unless youve seriuosly neglected your engine and beat the shit out of it it shouldnt be having major internal problems when only 3 years old... shame on chevy for even having lifter noises before 10 years

Have you tried changing the oil again, I changed the oil in my truck when it did that and it stopped, it started again about 1500 miles later, flushed the crank case with motor flush, found at any parts house, it looked and smelled like diesel, which would probably work as well, mine had a sludge build up. It still makes a slight noise at start up on cold mornings I plan to flush it again at next oil change. Hope this helps.

I have a 2009 chevy silverado and it has the same problem ( TICKING FROM THE MOTOR) . OSCAR THE GROUCH !!!

Chevy has used grade 5 bolts on many of their trucks to fasten the exhaust manifolds. They need to be grade 8 bolts. Look to see if some of your bolt heads have snapped off and get them replaced. A leaky manifold sounds like and engine tick when the gaskets are cold. The sound goes away when heat expands them.

Had oil changed today at Chevy dealership 2009 chevy.....tapping/knocking noise......of course I'm female so I've been freaking out.....hubby said every chevy he's had has done this so he put Lucas oil in so.....fingers crossed!!!

grade 8 is overkill for exhaust, but yes could be exhaust leak. Have you checked the oil level in the truck? it requires 6 quarts of oil as opposed to the normal 5 quarts. The 5.3 i've seen to be hit or miss for some, i've seen some have over 200k miles and still be strong and some fail before they hit 50k miles. Lots of things can tick, valve train, injectors, exhaust leak, spark jumping, assesories.

Same problem - ticking or knocking noise very noticeable at idle on my 2009 Avalanche. I have 92K on it and just noticed it after it also began to run a little rough from time to time at idle.

46 1/2 years mechanic I don't know everything but I know chevy and own a 2007 Silverado 5.3.Its the third one I've owned and two knocked.Belive me its a piston noise period.Take oil filler cap off and start if it's lifters or rockers (which lifters take up slack and have 125 thousands travel) you'll hear it on top in.Lifters travel half the speed crank or Pistons travel thanks

This may sound too simple but if it helps someone else ... so be it ! I have a 2009 Silverado 1500 LTZ that just started a bad ticking noise a few days ago and was driving me nuts. It has a touch over 112000Km (yes I'm Canadian) immediately got it in the garage and the early diagnostics went from mild to wild ... was scaring the crap out of me ! Anyway long story short, mechanic suggested an oil change to try first ... he suggested a Full Synthetic Oil with Dextos (according to GM recommended after 2011's). Thought it was a sham but hadn't gone over ten blocks when all noise stopped (quieter than ever). In the past couldn't see cost difference for Synthetic but it's damn cheap compared to some of the other things he suggested trying if this didn't work ! Hope this helps even one individual and it will be well worth it ! If it works would appreciate hearing from you at rafeke65@gmail.com Thanks ... Dave !

I have a 2006 Silverado and mine started knocking at 175K miles. I've been using Valve Medic and it tends to work well to quite the knocking. It occasionally knocks on cold mornings, but tends to quite down after about 5-10 miles and when the engine warms up. I'm at 231K miles now and it's starting to knock a little more often. Has anyone tried Valve Medic? If so, how does it compare to other products? Is there a better product to quite Lifter noise?

My husbands 2007 Chevy Silverado (74,000 miles) truck just recently started having a knocking noise to the lower end of the motor which is noticeable when parked on when in low gear. No warning lights/no oil pressure issue/no smoke out of exhaust. The truck had a 7 year/70,000 warranty that has expired. Prior to the expiration, my husband reported high oil consumption. The dealership is claiming that the oil consumption has nothing to do with the lower end knocking sound. They are pulling the oil pan to look for medal shavings and to identify the cause of the sound. This is a 4 hour job that will cost $400. Does that sound right?

Kind of late on the subject, but: I have a 2007 Avalanche, 210,000 miles. Been a good truck up to this point. But, it has always used oil, no leaks or smoke. However, recently I had a tap in top of motor, and light came on for p0300..Miss on # 4 Cylinder. Stabilitrac light also came on. I check plugs, and two were very dark ( only 3 months old). I pulled the heads off, and I am in the process of replacing. I am also going to replace the lifters . Hopefully this will take care of the problem.

I have a 07 Silverado with a 5.3 V8 with 97000 miles. I noticed a "tick" about 3 weeks ago that is the loudest when I listen in the driver side wheel well. I thought maybe I had a bad batch of oil so I changed it again using a synthetic blend. Had no impact on the ticking. When I first start the truck it does not tick but after it warms the ticking becomes very notifiable. I took it to the Chevy dealer and they kept it for 2 days and are unable to find any problems. Their head mechanic took me aside and said he has an 06 Silverado with the same motor with over 200K miles and said his has been ticking just like mine since before it had 100K miles. He said it is a knock sensor and nothing to worry about. He showed me his truck and sure enough, it ticks just like mine. He said it is just a "Chevy thing" and will not impact the performance or longevity of the motor. I have no alternative but to believe him so my fix is turning the stereo up and the AC on and I cant hear a thing.

JUST BOUGHT 2 TAHOES WITH THE 5.3 lmg CODE ENGINE. One a 2010 with 132k was taken out of service cause of ticking noise. When it was delivered I drove it hard home and ticking noise has not returned. Did a oil change a week after and been a month still quiet. Other is a 2009 with 144k same issue but continues. when started sounds like exhaust for 5-10 seconds then the tick will sporadically come back as driving or sitting at light and oil pressure will drop. had a code for oil pressure switch but it would not cause actual oil pressure to drop. so thinking Pump or worst case the DOD valves and the replace lifters and cam, although oil came out dirty but clean of any metallic flaking.

I have a 2014 GMC Sierra 5.3 crew cab. I started hearing a loud knocking/ticking sound coming from the motor for no reason from one day to the next. I tried everything... changed the oil, checked fuses , oxygen vacuum sensor and nothing seemed to be it. Believe me that noise was stressful. Anyway one day I started messing with it and touching everything in and around the motor making sure that nothing was lose or unplugged and sure enough, I found the problem. It was a spark plug cable that was lose and misfiring. After I re-connected and secured the cable, the noise GONE!! Just make sure all spark plug cables are plugged in all the way.

We bought a new 2009 Silverado Texas Edition truck in April 2009. We only used the truck to tow our TT and around town so basic warranty was up when a ticking noise occurred. Took it to Chevrolet dealership and lifters and cam shaft had to be replaced, under the 5 year 100,000 mile warranty. One year later, same thing happened and dealership replaced cam shaft and lifters under warranty. Then three more times this occurrred again and truck was out of warranty by years not mileage and the latest time was June 2016!!! Even Chevrolet dealership told us we should repair it and trad it in on another truck--- well we have always bought Chevys but we were done with Chevy trucks...we traded our truck in on a Ford F-150 Platinum that a close friend of ours was trading in on his new 2016 F150 Platinum truck. Dealership let us buy our friends truck for the tradein value they were giving him for his new truck and took our 2009 Chevrolet Silverado in on the trade. We lost money on the tradein of our Chevrolet truck but we were done with repairing it over and over agin for the exact same thing. Word to the wise, we should have driven the truck and not just " saved" it for vacation trips, as this truck was a lemon and we would have used that law to give the truck back to GM.

I found out the tapping/clattering noise is caused by a bad O-ring on the pick up tube connecting to the oil pump. Changed whole pickup tube with the new o- ring and no more problems. Now Oil pressure initially on cold start jumps to 60 and as the motor warms up it drops to a little above 40 at idle and increases with Rpms and speed to about 60 at 70 mph. Before changing the pickup tube oil pressure was around 35 at startup and barely above 40 when driving. After driving a while and a lot of engine clattering it would build pressure to between 40 and 50 and eventually the tapping would stop until I idled again for a while. Glad to have this problem solved,

Knock sensor

1 of 1 people found this helpful.

Knock sensor is letting the timing become advanced too far and a rocker is tapping, mine has done it for 3 years, and it stops once fully warmed up, and mine has 200k on it, and also does it worse when needing an oil change . .. it can't. Be a piston or it Would have cratered by now, and s loose rocker would tap all the time and if it were a lifter the push rod would have already gave up, I hit 6500 fairly often and it seems to be bulletproof...

Do NOT let them tear into it, it will end up being a big waste of money, and the problem is they are all computer techs now instead of mechanics, go to an old school mechanic and he will explain it better, but mine has done it for a 100k, but as long as it runs and doesn't tap completely warm it's all good, plus these motors were actually made for high powered camaro , not really for trucks, and high hp motors have a lot of clearance so they can wind way up..

The oil pump O ring makes the most sense, the actions of the oil pressure and when the noise happens, indicate oil pressure issues caused by the oil bypassing the pump. Thanks mposey9293!


I fixed this problem on my truck by changing the Oil Pump Inlet Tube O-Ring. The lifters are the first part that don't get enough oil after this o-ring breaks down. All Chevrolet mid 2000s era 5.3L O-Ring fails around 150-190K. Oil Pump Inlet tube O-Ring Replacement https://www.youtube.com/watch?v=g1e3kx3mOMY
