Ticking noise question - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

bklyn_tap · 06-25-2012, 12:31 PM

I've owned my camaro for over a year now and recently had it at my buddy's shop so they could install my new exhaust. He found 2 issues while working on it. The front timing cover was leaking and the valve train is making a ticking noise. Since under warranty I brought my car in a week later to my Chevy dealer and they fixed the leak but claim that the ticking is normal. I feel like theyre wrong. What do you think I should do? Anyone else with this issue?

I had an issue with a ticking noise for a heater hose/check valve. I'm not too mechanically inclined, but it was common in 2010s. Can you elaborate on the ticking noise? Where is it coming from/Can you hear it in the cabin?

bklyn_tap · 06-25-2012, 01:02 PM

You can hear it when the car is idle from the outside. It's coming from the valve train

Yeah, don't know what to tell ya. Mine only made the ticking when I was accelerating and the RPMs were about 3K-5K. Dealership tried to tell me it was the exhaust (only aftermarket thing on my car) and it wasn't covered

. Found this thread with a TSB on it and they fixed it the next day.

I don't know if it's the same issue, kinda doubt it, but check it out and if it sounds kinda close you might take that TSB # to them.

Good Luck!!

Yeah they're quick to blame it on mods. Mine just does it at idle. Not a huge issue but when my friend tells me he thinks it's wrong but the dealership says its "normal"., I'm going to second guess the dealership. Thanks for the help.

Hard to say without hearing it in person. Valve train noise is loud in these motors. Could very well be normal. Headers make it a lot worse.

I have had my Camaro for three weeks, I hear that ticking noise as well and was wondering if it was a issue.

amartinez · 06-26-2012, 08:35 PM

My LS has made that noise since I bought it and I've heard it in many exhaust sample vids. I gotta say it's a normal thing in the v6.

Patrick864 RS · 06-26-2012, 08:57 PM

Yeah I've read number of threads on here that state the "ticking" noise from the engine is completely normal on the v6. When I first heard it I reacted the same way. But it's just something our car does...

My friend has a V6 Camaro. His diagnostics pointed to the injectors on the LLT motor. Normal and noisy was the verdict.

Has this issue already been addressed by your dealership? Several things could be the ticking noise that you are experiencing. They should be able to address this concern you are having.

I was told by 2 dealership and a TSB is issued that the noise is from the High Pressure Fuel Pump. They even show me the paperwork on it.

Only problem i had is we started up a New 2011 LLt and it didnt have the same noise?

My noise is very noticable at idle and when the gas is pressed goes up slightly.

I dont wanna bring it into another dealership because even tho car is under warranty they are charging $90 to look at it.

Here is the TSB for this issue, nothing to worry about, totally normal for these 3.6l engines.

This bulletin is being revised to add the 2011 model year. Please discard Corporate Bulletin Number 07-06-04-025E (Section 06 - Engine/Propulsion System).

The 3.0L and 3.6L SIDI engines (RPOs LF1 and LLT) use a direct injection fuel system that operates at very high fuel pressures. A direct injection fuel system produces a rapid clicking and ticking sound that can be heard from the engine compartment. The sound is more evident when outside around the vehicle or when the hood is open. The sound is more noticeable during idle and is more frequent during a cold start, but lessens once the engine is warm. The rapid ticking noise on cold start up is the fuel pump (located on the rear of the left cylinder head) building up high fuel pressure. When the engine warm-up is completed, the high pressure fuel pump will continue to tick at a lower rate of approximately one tick per second during idle. The clicking sound is the fuel injectors pulsing on and off under higher fuel pressures. These sounds are the results of a normal direct injection fuel system operating properly.

DO NOT attempt to repair or replace any parts for this kind of clicking or ticking concern. The clicking or ticking sound is not indicative of any concerns with the engine or the vehicle. You may wish to give the customer a copy of this bulletin.
