Lexus LS 2007+ :: Engine Ticking Noise At Idle - Possible Remedy
Apr 13, 2015
While searching on line for information about the LS460's engine ticking noise, I came across a fascinating engineering paper. It explains the source of the noise in all GDI engines and proposes two solutions. One is not feasible as it would require some further development of the engine but the other solution may be practical for the DIY enthusiast. The question would be what type of material to use which would withstand the conditions under the hood?

With the motor running and the air conditioning on, there is a intermittent ticking noise that comes and goes. It may be the compressor coming on and going off.

I recently hit 180,000 km on my mileage and all of the sudden theres increased ticking engine noise and vibration. Sounds like a diesel engine. No check engine lights, gas mileage is the same, acceleration is the same and as far as I can tell after checking oil its within normal range for now.
I'm worried its either the VVTi Rubber hose exploded or its the VVTI Camshaft / piston slap issue. My dilemna is I'm 3 hours drive away from a Lexus dealer but there is a Toyota Dealer 10 min away. Should I bring it in to verify theres no oil leak at Toyota and then take it back to a Lexus mechanic to see if it is Camshaft gear ?

Strange ticking noise that you can hear in the cabin sounds almost like a exhaust leak or a fan blade ticking something under the hood.. I have had the dealer check it they say nothing is wrong i just can't believe a 75k car can have this noise...

I bought my car CPO but the svc records show the VSR recall was done just a few months before I bought it. I brought it in one time for the noise and they said it is normal, just a high pressure fuel pump noise.

I finally jumped from MKII land into a new GTI . Is it normal for it to sound like a diesel when at Idle? Its only really noticeable when you lift the hood. Im used to my MKII with sticky lifters but the sound of the TSI seems a bit loud.... I haven't been able to compare it to another car.

We have a 2004 Passat V6, and we've noticed at idle, the engine makes 5 or six fast ticks, stops, then goes again, over and over. I tried searching but didn't find anything relevant.
Also, sometime when the AC is on, all of a sudden the air stops coming out, but the blower still roars, then a couple seconds later the air comes rushing out of the vents again.

Experienced a noise that is evident when the side window is down which seems to coming from underneath the car. It is difficult to describe but it is a ticking / light metallic sound. Possibly coming from the exhaust system area. It is particularly annoying at a drive through window where the sound reflects off the building.

I have an 07 Camry with an I4 engine and there are times when I am driving with the two front windows down and I hear a ticking/clicking noise coming from the engine as if the engine is brittle.

I have a 2009 Santa Fe that when the engine has warmed up, the engine starts making a ticking/clicking noise. The dealership told me not to worry all cars make that noise and it was probably just a purge valve. Does this sound right?

Is this normal? I've heard this is normal for all Toyotas/Lexus? I just picked up my 2013 a week ago and didn't notice it?

2010 F150 ... So I have the tick noise at rpm's 800-1000 at drive through, stops, etc. So I did research on it a few months ago and saw that it might be VCT's but should be able to drive. so I drove it waiting to save money and have it go to a shop. well this past weekend while coming home from work my oil light came on the pressure dropped to zero, I was on the highway so I drove about another mile to get off highway and once I got off my truck died. I had it towed to my house and I thought I blew my motor. So I started doing research here and found that the VCT's AND cam Phaser could be bad. so I replaced my VCT on driver side put it all back together it started and loud knock was gone. then after 5 mins it was back very loud knock!
So I shut it down and took apart the passenger side once I got the valve cover off I found the problem.... The bolt that holds the cam phaser in place snapped off and was riding along the camshaft. So I took that out and extracted remaining part of bolt. inspected my camshaft and it was really messed up. so I bought new Phaser and Camshaft. the camshaft just came in today and I am trying to put it back in. but the hole for the pin in the phaser doesn't line up and I cant spin the shaft to make it line up. should I spin the cam phaser? I marked the chain and the phaser is where it should be on chain, but with that bolt snapping off could that have thrown the timing off so my mark is no good? when I lay the camshaft in place it sits perfect and if I just move the phase over 2-3 links it will all fit together. Should I do that?

Today was the first time I was in my RX without the radio since I bought it. I have a 2011 RX CPO with 65000kms on the odometer.
When the vehicle is idling there is a tick-tick noise coming from the engine area that does not go away. I initially thought this noise was due to it being 0 Degree C but the noise continued for the duration of my 45 minute drive. Later in the day the noise was consistent was did not silence.

At idle, it sounds like a little diesel engine humming along. Everything is turned off. Does your car sound the same at idle? 2011 LS460 Sport

Had the car for over a week now, noticing a clicking or ticking sound at idle- i.e. no radio and at a stop light. Slightly annoying, but the car has been great otherwise.
2015 new gs350 f sport.
It is not when i am making turns, just sitting idle with the wheels straight.

I have a 2011 LS 460 with 28K miles in very good shape although there is a noise most audible when I am in a stop sign that disappears when I shift the transmission to "P". The noise is like a tackat tackat tackat tackat . I took the car to the dealer and the service advisor claims is normal. Is it or my car is defective?

So for the past several months i have noticed something going on. There is a little noise almost like a groaning
- When i am at a Stop light and idle but still in Drive.
- When i shift to N or P it stops and goes away.
Sometimes during this i will notice a little rattle or i feel a little vibration but not much and very hard to even notice if it hadn't been for how sensitive i am never would have even noticed this at all. What this could be ?

I have a 2007 Camry LE, with about 104,000 miles on it. Lately I've noticed a noise ONLY when the car is idling, rather in park or drive. I don't hear it all when I'm driving. It's somewhat hard for me to tell if it's coming from the engine or under the car, but its definitely near the front and sounds lower in the body. My first instinct told me that it was related to the exhaust system, but it doesn't quite sound like a rattle. It sounds closer to a belt struggling to turn...it actually sounds a little bit like when my water pump and alternator went, but I had those replaced 15 months ago so I really don't think it's that at all. I also had the radiator replaced 2 months back, so I don't think it's that. I don't know drive far to work, so I haven't put a lot of miles on the car in the last year.
Otherwise the car drives normally, just hear this sound at idle. The only other thing I've noticed over time is that when the car gets to about 2500-3000 miles after an oil change, I notice the light flashes when making hard turns..but that's it, and it goes away when I get the oil changed. Obviously I know that the engine is burning oil probably faster than it should, but I'm not sure if that might somehow be related to what I'm hearing above.
