Lexus LS 2007+ :: Engine Ticking Noise At Idle - Possible Remedy

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?

Hopefully you can open the PDF attachment I have included : isma2010_0514.pdf

It will take a few seconds to open the file depending on your download speed.....

Lexus LS 2007+ :: Ticking / Rattling Noise Coming From Underneath The Car

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.

Lexus ES 2007-12 :: 2008 ES350 - Engine Ticking Noise And Vibration Increased

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 ?

Golf VI R :: Getting Ticking Noise Idle In Cold Weather

In the cold weather I found I had what sounded like ticking noise at idle on the R. It doesn't do it when first started and I didn't remember it in the warmer weather either. My research indicated it could be the DI injectors or the N80 valve. But what got me concerned was that I could hear the ticking inside the cabin, somewhere in the front passenger footwell area. And at times over normal radio volume. This was not the case in any of those other threads on the issue as they noted the sound only outside the car.

So I took the car into the dealer this morning to see what they would say. Had a good tech check out the car and try a few things. Turns out the tech found it was the fuel line underneath the car rattling. He said this was a common issue in the MK V cars and there is a service bulletin out on it, but he had never seen it on a MK VI car.

Passat (B5) :: Engine Ticking Noise At Idle / Air Sometimes Stops Coming Out When AC On

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.

Ford F-150 - 1997-2003 :: Ticking Noise Would Be At Idle Or Under Acceleration

About a week ago my 1997 F150 4.6L 2WD starting a ticking noise. I had used high mileage full synthetic Mobil 1 and a Motorcraft oil filter for the previous oil change and yesterday had another oil change using regular Mobil 1 synthetic and a Motorcraft oil filter. Had never used high mileage oil before.

Since the high mileage oil is supposed to have extra cleaning agents in it to remove the sludge buildup in the engine, could the sludge have found its way into the oil pan and possibly clogged up the oil pickup tube? The ticking was not continuous and would be at idle or acceleration.

No rhyme or reason to when you would hear it. I also wonder about an exhaust manifold leak which could sound like ticking. If the problem is an oil pickup tube being clogged up, can the oil pan be removed with the engine still in the truck?
