Question about 2005 Chevrolet Corvette

Clicking from motor at start up. Goes away after a few minutes

2005 Corvette makes clicking sound at start up in the morning. Clicking is rpm sensitive. In the old days I would have guessed it was lifters/valve related. I am thinking that it may be fuel injector related but don't know why it would go away after driving a few minutes if it is from the injectors. Anyone having similar problems or ideas about how to fix?

    Yeah, that one didn't help much. I tried your idea but the sound continued. Had the car to the dealer for fuel door release problem and mentioned it to the tech. He suggested an induction cleaning that was due at 30k miles (I'm at 25k miles). I figured it was a long shot but went ahead and had them do the service. Started the car this morning and the sound was gone. We'll see how long that lasts but for now I am satisfied. The tech mentioned that these engines are prone to "piston slap" (whatever that is). That may be the case but my problem came on fairly abruptly, over a 2 or 3 month period. Hopefully I'm done for a while. Thanks for your input.

    Thanks for the explanation. It is easy to envision what you are describing and I agree, how could it wear to that point in 25k miles? Anyway, thanks for your input. Take care. N32CW

    New question: While stopped with the car in gear (automatic transmission), the rear end seems to be a little noisier than when new. Tech at the chevy dealer said it was coming from my "torque tube". No big deal but time consuming to fix. Any experience with torque tubes?

  • n32cw Sep 17, 2009

    I was thinking that it may have something to do with the "half shaft" that runs from the differential. I plan to call the tech to pick his brain next week.

    piston slap is when the skirt (lower edge)of the piston wears sufficiently for the piston to move across the cylinder at the end of the strokeand "slap"against the opposite wall causing an unpleasant noise not unlike a click or a snap .I would be cutting up rough if it were to present at anything like the miles you are at ,There is no reason to doubt what he has said about the induction cleaningseeing it seems to have worked(Ihave never heard of it but that is not strange technology is moving too fast for the oldies like me) all the best "youdoit"

  • kerry littleton Sep 16, 2009

    back again. you have got me stumped.I also rang my mate who runs PERTH 4WD CENTRE and he was at aloss also ,by the name torque tube one would be expecting it to be a suspension component,like a torsion bar but that cant make a noise unless it is rattling against something. Sorry I cant help ,youve got me interested now ,Iwill make some more enquiries from another mate who has a racing team , if I find out iwill get back to you "youdoit"

    HERE WE GO ,TORQUE TUBES FIRST CAME OUT IN T MODEL FORDS ,I AM LED TO BELIEVE BUT IF YOU GO TO THE NET GOOGLE UP TORQUE TUBES ON WIKAPEDIA OR WHAT EVER IT IS CALLED AND YOU WILL LEARN ALL THERE IS TO KNOW ABOUT THEM . THE OTHER THING THAT GARRY(THE RACING BLOKE)SAID WAS THAT THERE IS NO WAY THAT A TORQUE TUBE COULD MAKE ANY NOISE STANDING STILL , HE SAID TO TELL YOU TO CHECK YOU EXHAUST FOR A LOOSE CLAMP ANY WAY THAT IS THE TORQUE TUBE QUERY TO THE BEST OF MY ABILITY ALL THE BEST -------"YOUDOIT"

Engine problems


intake valves on the R side of cyl.head.exhaust valves on L side looking at engine from transmission end. need to perform a compression test on each cylinder making sure that the psi doesnt vary by more than a cpl. psi between cylinders.FUEL INJECTOR is very likely.AND injectors make a clicking noise when energized.a click each time injector is pulsed.(thats each time the cylinder is fired=alot of ticking or clicking)the higher the rpm the more rapid the noise.injectors are on the intake side of cylinder head. opposite side from exhaust manifold(the manifold that your tailpipe attaches) unplug injector on no.2 cyl(if thats where your misfire is) while the engine is running, if the engine runs the same without staggering or stalling there is your problem. good luck and happy motoring ___O^-o

Need to know how to adjust valve lash on a big block 454 with roller rocker arms and hydralic roller lifters ? A video whould really help


The old fashioned way was to connect everything up and tighten the nut on the lifters until you could no longer turn the pushrod and then add about a quarter turn. Cover the lifters with a rag then start the engine with the valve cover off and loosen one lifter at a time until you hear it clicking and then tighten just until the clicking stops. Do that on all lifters ona at a time. Whe complete go back and add one quarter turn to each lifter.

I have a 2007 corvette with 5.7 engine 27,000 miles which sounds like just one lifter is making a clicking sound after it gets hot. Is there an additive which will stop the noise?


I would just pull the intake and change the lifters

You shouldn't have thoses issues,it is only
4 years old

Keep in mind I had a 1965 Vette brand new
and had it apart all the time,so that is why 46
years later I'am still at it

No additive will be a fix long term

Ticking noise from engine


The most common reason is the hydraulic valve lifters. The short term fix is to

a) replace the oil and filter if this has not been done recently.
b) Rev the engine to 3000 rpm and hold for 30 seconds. This pumps up the lifters and helps clear old oil.
c) do this 2-3 times until the clicking stops.


The longer term fix is to replace all 16 lifters.


Other more expensive reasons are
a) a big end bearing. This sounds more like a hammer on anvil hit, and its louder if you blip-rev the engine. Rev to say 2000 and back off slightly and the noise stops. The fix is a replacement engine or engine rebuild.

This is a 2000 dodge intrepid r/t i just had the radiator replaced and a battery put in, the problem is now they said that my engine was clicking because i need an oil change i have never heard this before...


if the car has hydraulic(oil) lifters on the camshaft that operate the engine valve sytem and the clicking noise is in this area ,,,
then a oil chang will boost the tired oil from the lifters and flush the old oil out ,,making the car run a lot better

My 1994 cadillac eldorado is knocking hard its comeing from the top end ........maybe a bent lifter of valve idk im just guessing though


probably a failed lifter. Is it a tapping/clicking sound? You can troubleshoot by taking off the valve cover. Put some rags down around the head to catch the oil that will splatter when you start the engine. Run the engine with the cover off for just long enough to see which lifter is not pumping oil or opening it's valve. If this is clearly indicated, the lifter must be replaced to avert further engine damage.

What could be making a loud clicking sound toward the back of the motor in a 2002 Grand Am and how can it be resolved.


The only thing that could be making a loud clicking sound, is a bad valve lifter. If the clicking speeds up with speed of the motor, it's a valve lifter, either the rocker arm needs to be adjusted, or the lifter needs replacing. Which means the whole top part of the engine needs to come off.

My 2005 hyundai elantra wont start


Sounds to me like your charging system failed and you now have a dead battery.
You will likely need to replace your alternator.

I just bought my 2004 Acura TL 2 weeks ago. It


What you describe is consistant with a lifter not pumping up except at a little higher rpm, which would make sense. You have overhead cams, with hydrolic lifters. They pump up with oil. If you have one that is not fully "pumped", it will make a clicking noise when the camlobe moves it and it strikes the valve. This is not the only thing it could be...and maybe it is the tensioner, but if it is coming from the valve area....Also, your dealer should have a special stethescope so the mechanic can listen in spots, and move the pick-up to where the noise gets louder and make a better diagnosis.
