: TICKING Noise.....

Im trying to figure out what this ticking noise my V is making. Unless this is normal i really dont recall it making the noise before. It seems to be coming from under the car, maybe the tranny?

Its really annoying, usually i cruise in and out of the neighborhood in 2nd gear @ about 2000RPM (because i like the sound of the exhaust) but now i hear that ticking noise and it annoys the crap out of me.

It ticks pretty quiet when its idleing, It ticks when the clutch is pushed in or left out, in gear or out of gear. The ticking will speed up and get a little louder with RPMS.

I looked around on here and couldnt find much except for someone with a loose spark plug. SO i changed all my spark plugs considering im at 60k and not one of them was loose. No idea what the noise is but its drives me nuts and the caddy dealer will probly tell me its "Normal" and then hand me a bill.

The only other thing i think it may be is a loose exhaust connection, i had my Cat replaced over the winter by the dealer.

Am i just crazy or is this ticking not normal? my tranny also sweats like crazy, i was wondering if thats normal too. It leaves a wet trail when i pull into the driveway and drips quite a bit when i park, but it seems to be only condensation?

Thanks guys.

Could be an exhaust leak or a noisy lifter.

The "sweating" is probably from your AC vent.

I agree with both of those. My a/c pours condensation from the 'vent'. It comes out by the drivers side of the tunnel by the bell housing.

Yes thats exactly where it drips from. Now, if it was a noisy lifter would the sound be coming more from the top of the engine? Because its deff coming from underneath. If this noise ends up being an exhaust leak from when the dealer installed my new cat than its time i find a new caddy dealer. They Litterally cant do anything right

Probably a leak at the junction where they bolted the cat to the exhaust manifold.

I have a similar ticking and had it jacked up with car running and it seems to be coming from bellhousing. Could it be dual mass crapwheel or possibly throwout bearing? Mine is an 04 w/ 115k.

Had some extra time this weekend so i jacked up the car (still havnt brought it to the dealer) no noise coming from the exhaust junctions which was what i was hoping it might be. Like yours the ticking was coming from the bell housing area...

The noise hasnt got any worse though which i guess is a good thing. car only has 60k miles

My car also has a ticking. While it was still under warranty they even changed the heads. Supposedly all the lifters checked out ok and everything else looked within tolerance. I have personally taken the transmission off and changed clutches/flywheels. Running it without the transmission on it was quiter. My noise will now come in go depending on when I start it, it will be throughout the drive or not. It does not change with temp. I found a 06V at a dealer and took it for a drive and it also had the noise they also had a GTO with the 6.0 same noise. I am less worried about it now all though it is annoying. I am also running 10W40 oil now which may have improved it some. Next oil change I am going to 10w30 but this will be right before I put it away for the winter. Check out my videos is it the same?

I think its the flywheel more and more on mine. Thinking of doing an LS7 swap this winter. 115k on stocker is good enough.

BTW mine sounds louder while idling, if that makes sense. It does tick while driving but seems more pronounced while idling.

I need to fully flush my slave instead of sucking it out. That may help if its the throwout bearing riding on the pressure plate.

Im thinking that is a similar noise as mine, my exhaust is pretty loud so you cant hear it that clearly only at certain RPMS. Its the loudest usually around 2 grand, still does it at idle but a little quieter. Do you have any videos under the car while its idleing? Il get some videos of mine up soon.

Does make me feel better that others are having the same sound, but with no negitive feed back other than an annoying sound. could be the nature of the engine/tranny....

I have the exact same problem too! I can hear the ticking slightly at idle but more so at 2K RPM+ and the ticking increases speed with the RPMs. It happens when in gear driving or just sitting idle. It does sound shitty, it makes my V sound like its ragged out. I first noticed it a few weeks ago driving through a parking lot in 1st gear with my windows down. I can only hear it if my windows are down...if my windows are up I cant hear it inside of the cabin. My exhaust hasnt been touched except for a muffler swap.

I'll try and get a video up this weekend.

YES. Without hearing a video that 100% describes mine. Still post a vid, il try and get a vid up this week. Has anyone had this noise and changed a lightweight flywheel with any improvements?

PS. took a ride in my buddys 02 corvette 5.7, 3" exhaust high flows and headers......you could hear it slightly on his car too, alot quiter though.

Mine was worse with the LS7 clutch. I hope to put the clutch back in within the next few weekends and I will see if it is worse again. At this point the stock clutch/flywheel is rattling so bad my car sounds like tumbling rocks at idle in neutral.

It's piston slap and valvetrain noise, and all LS6 engines have it to some degree. Mine became a lot more noticeable when I did headers, and I drove myself crazy trying to find it- two sets of new manifold gaskets, welding up the connections in the exhaust, pulling heads, etc.

Quick Google Search for "Piston Slap LS6" (http://www.google.com/#sclient=psy-ab&hl=en&source=hp&q=piston+slap+LS6&pbx=1&oq=piston+slap+LS6&aq=f&aqi=g-v1&aql=&gs_sm=e&gs_upl=979l3600l0l4035l15l12l0l0l0l0l605l4320l0.1. 4.3.1.3l12l0&bav=on.2,or.r_gc.r_pw.,cf.osb&fp=a0af293b98df815e&biw=1280&bih=679)

Pretty much all of the LS series engines (LS2, LS6, LS1, etc) have it to some degree. Some are better than others, and it seems to become more pronounced if you take off the stock iron manifolds.

Your noise might not be what mine was, but it's far too common to overlook as the potential cause.

Sounds just like mine. My cats had also been replaced before I got my car. I had pulled the cats and found that one had a little bit of pipe above the flange all though we fixed this it did not make a difference. I would take off the exhaust and check the gaskets one of mine did have a leak and made the noise even louder. There is something common here and hopefully it will be figured out eventually I would love to get rid of the noise completely. I think the noise is actually echoing into the bell housing and transmission that is why it was louder when I had the LS7 clutch on it.

Got a video of the ticking this afternoon. RPMs were at 2k, then 2-3K so you can hear that the ticking increased speed along with the RPMs. The ticking sounds horrible when the sound bounces off something IE: wall, passing a car etc. I tried getting the bouncing sound on video but you cant hear it like you can in person so all I could get is the rev.

That really sounds like a rod. But it could be a number of things. How's oil pressure.
An old school way to rule out a rod knock was to pull one plug wirewhile at a time while the engine was running. If the tick/knock went away then it was that cylinder that had the issue. Not sure if that would screw with the computer or coil ,maybe someone else can answer that.

Im in no shape, form or fashion a mechanic so forgive my ignorance but if it was a rod knocking wouldnt it get worse and louder over time? Its not that loud and its been making that sound for almost 2 months now, probably longer than that and I dont baby it, I do drive it hard.

My Tundra had almost the same sound and I took it to 2 different Toyota dealers and they said it was normal. I even took both of their head mechanics for a test drive so he could hear the noise bounce off of the wall. Some other Tundra guys had the same noise and everyone on the Tundra site said it was injectors or a leaking manifold, which the 1st gen are notorious for having. I just though it was loud injectors......

How's oil pressure.



Cold idle - 44psi
Warm idle (oil warmed up to 203) - 31psi


Driving in 2nd gear:
1500 RPM - 46psi
2K RPM - 48psi
3K RPM - 55psi
4K RPM - 59-60psi

No updates on this yet? I really need to bring mine to the dealer and see what they say, I just have no other means of transportation which means i would have to take time off work and sit there with the car....

Sad part is 90% of the people on here probably know the problem more by listening to one of these videos than a caddy mechanic will by seeing/hearing it in person. morons......

10-20-11, 07:05 PM
When looking at youtube there was a Z06 that has the same noise as mine. Turned out for him at least, it was an exhaust leak and a spark plug. I dont know what the problem is. I took off the valve covers last night and didnt see any damaged rockers or springs.

Ive heard it could be alot of different things from exhaust leak, bad lifter, rocker arm, spring etc. and Im not paying a shop to start replacing parts until the ticking goes away because theres a guy with a GTO that say he replaced alot of stuff and the ticking is still there!!? In case you didnt see my thread on the other site ---> http://ls1tech.com/forums/cadillac-cts-v/1477884-ticking-noise.html

Ive put over 4K miles on my engine since I heard the tick and its hasnt gotten any worse or louder. I have a recall I still need to get done on my V so I'll have the Cadillac dealer take a look at it and I'll probably take it by my exhaust shop and see if they can possibly find an exhaust leak. The noise does suck but I dont have any hesitation or loss of power so for now Im just going to keep on rollin!

mcline86
10-20-11, 07:50 PM
Same here nothing seems wrong i just hate the sound and want it gone! Like you said though it hasnt gotten any worse and its been doing it since the weather was nice enough to put my windows down.

I also have a recall, the passanger seatbelt sensor or something? I will probably do the same - have them inspect the noise when i have time to get it in for that recall.

10-20-11, 07:55 PM
my cars ticking got louder after I put on my headers. I also have a small exhaust leak, but I can differentiate the valvetrain noise and the leak. My car has new springs pushrods and lifters so I dunno if that maybe did it

Yep, thats the recall. Let us know how it goes....I have to call my Cadillac dealer this week and see if they have the part in. I took it in about a month and a half ago for the recall and they had to order the part.

10-24-11, 08:25 PM
Took it to Cadillac today to get the recall done and I had them check the ticking noise. They said it was normal and I even had the head technician listen to it with me revving the engine....he heard the ticking and said it was the injectors.

JFensty
10-24-11, 11:06 PM
Seems like if it was the injectors, the sound wouldn't be louder under the car. ?????

texasseville
10-24-11, 11:54 PM
I posted a long video on the other site with the hood up and hood down and it's louder with the hood down so that tells me the noise is bouncing off of the underside of the hood. I had the exact same ticking noise on my Tundra, as did many others and it was either the injectors or a cracked manifold. 9x out of 10 it was just noisy injectors.

My engine runs strong. I have no sporadic idle, no hesitation in the lower or upper RPMs and no check engine light so I don't know what else. I even asked the tech if it could possibly be a bad lifter / rocker and he said the ticking would be louder if it was either of the two.

mcline86
10-26-11, 04:06 PM
Friggin cadillac technicians suck. If its "normal" and its just injectors howcome they didnt make that noise before? and I would think if it was injectors it wouldnt be so loud from the bottom of the motor? IDK....

I wont be able to get my car in for a couple weeks until work slows. But one thing i noticed today when I started my car with this colder weather (it was about 47 degrees this morning) I started my car up, windows up, and I could really hear it ticking away even louder, sounded like rocks tumbling around under my shifter, then it warmed up a minute or 2 later the noise got a little bit more quiet and did just the typical ticking noise it does.....

Hey guys, im glad I see a thread on this topic cuz it finally gives me a chance to post about a similar issue. Randomly I will hear a ticking noise coming from somewhere in or behind the dash. I can't recall when it's worse or vice versa, but it's really annoying and I hope it's not something expensive on the car that could possibly be going bad. Any input/questions?

10-27-11, 08:23 PM
Not seeing very much input on this topic. Techs are saying its normal, some other people are saying its normal. Im sure theres many out there that dont make this noise, so i dont see why its "normal" especially since it didnt do it before. It makes the car sound beat. Id love to know the answer, i do have a warranty still but i cant wait to get my car in so their head tech can give me the "its normal" answer.

Oil PSI @ 2k: 44psi

1) Oil appears to be good and at correct level
2) Outside temperature was in the 40s. Maybe 44 degrees F.
3) I found engine cover a bit loose today (probably because I had moved it the day before and maybe didn't line it up right). After I connected it, I didn't listen for it again.
4) Clutch has roughly 100k miles, Flywheel has 119k.
5) My Motor Mounts are shot.
6) No power loss, no lights, no codes, nothing. Just the sound.

I can't even hear anything in your video. I wouldn't worry about a light ticking noise at all...but then I drove a car powered by a GM 3100 V6 for a few years...sounded like a diesel when it was warm, and like it was going to throw a rod when it was cold. Engine was solid, pulled hard (well, as hard as 160hp V6 can pull), and used no oil when I sold it at 195K miles.

If you want a smoother sounding engine you'd probably do best to find yourself a car with an OHC setup. But where's the fun in that?

Yeah its frustrating...I dont have $100+ dollars to keep throwing at different shops for their "diagnostic fee". I dont have a warranty on my V, so Id think if there was something wrong that would mean big $$$ to Cadillac for repairing it and or big money tearing it down to find out what is wrong if anything but their head tech said its normal as did the tech that looked at it when doing the recall. See my ticking was probably there since I bought my V back in Aug. I just happen to have my window down one day and heard the noise.

If your car was quiet then all of the sudden one day had a ticking then thats not "normal" at all. I hope you find something out....keep us posted!

10-28-11, 12:21 PM
Sometimes mine ticks when it's cold...sometimes it doesn't. Sometimes it ticks when it's hot, sometimes it doesn't. It always ticks after a hot lap on the Nurburgring. ;) For what it's worth the day I test drove the car on the lot, it was running quiet and not ticking...

If the motor runs strong, doesn't burn oil, and doesn't knock under load, I really wouldn't worry about it. *shrug*

odthetruth
10-28-11, 08:58 PM
The ticking is a bit more pronounced then in the video. Sounds like its either coming from underneath or from the passenger side engine compartment. LOL Oil is good money, and I'm seeing absolutely no CEL or dash lights at all, and no issues when running it hard.

[edit]
Noticed when running it hard at operating temp (both eng&oil)... the oil pressure psi was going up slightly above 70 (about 5k-6k). I'm not sure if this is normal... Outside temperature was a bit above 40 degrees.

I know this is a little late, my V has the same noise from time to time and is louder depending on the day. Are you still experiencing the same noise? I have had a number of conversations with a couple of local V owners, along with a few C5 Vette owners who tell me it is totally normal. They remind me that these motors are bullet proof and tell me not worry too much. My V is still under warranty and two Cadillac dealership shop foreman - who i know personally, tell me the same thing.
