Ticking Sound

What was the outcome of this issue? I’m having similar symptoms and the dealer is calling it an “Adjuster Valve Lash”. Happened right after an oil change at a dealership and was very noticeable but now I can only hear it faintly when in Drive and the windows down.
 
I was never able to figure it out. I had Lexus look at it and they said it was fine. I noticed that the noise occurs after oil changes but subsides after a couple hundred miles. I’m thinking it’s the valve train and when you drain the engine oil, air obviously gets into the system and needs to work its way out. I’ve gone another 30k miles and have had no issues. I tried 5W-20 oil too thinking the extra weight would remedy the noise but that didn’t help. This was based on what others have done to their Tundras with the 4.6L. Hope that helps and you don’t have something else to sort out!
Hi, any solution found for this? My 2023 Gx460 1000 miles also ticking....

Hi Noman, sorry for the late reply. I never figured out what the noise was.. Looks like someone in the earlier comments had an engine replaced under warranty. I'm thinking it's valve train or camshaft related. I don't have any performance issues but do still occasionally noice the ticking sound; I plan to run it to failure (if it ever fails).
 
Wow! A new engine!
A new short block, so the heads, etc. must have been salvaged. I guess this means the dealer did the rebuild of the old components to the new short block.
 
Hey guys, how common are manifold leaks on the 460? My 2013 has 73k miles and I've noticed a ticking sound that almost sounds like an exhaust leak but I only hear this when my front windows are down at lower speeds and low throttle input (can't tell if happening at higher speeds due to wind drowning out the sound). No ticking sound at idle, in park, etc. I can't hear this with the windows up either. I can try to post a video but the few I've taken aren't very clear.

I changed my oil just prior to hearing this sound with the recommend 0-20W Mobil 1 but am not sure the sound occurred as a result of the oil change since I live in Southern AZ and I've had my windows up all summer. I saw a thread while researching (on FaceBook) that indicated some people have loose spark plugs that were the culprit of this ticking sound. So, being that the GX is newish to me I went ahead and put in some new NGK's but the problem persists. Perhaps its a timing chain related issue or bad fuel injector? I don' have any check engine lights and it seems to drive normally for a heavy pig with 300 HP :).

I'm going to pull the front wheels off this weekend to see if I can find any evidence of manifold leaks but thinking I'll take it in for diagnosis at the dealership next week. Any ideas?
My 2011 does this. I noticed it after I changed the oil myself. I drove it down the road and heard the ticking noise that coincides with acceleration. It seems to be coming from the oil filter, housing, and the spring inside. But after a few hours, it will stop making the ticking noise. Mine has done this now for the past eight oil changes and probably more than that, but I haven’t paid attention until this past year. It does not seem to hurt the vehicle.
 


I remember reading about this on CL and member posting this.

Is this what you are having?

It’s the chain tensioner on the driver side. Mine has the same thing. You can only hear it at low speeds when you’ve got the window open and you’re like next to a building then you can really hear it, but we pretty much have this figured out at our shop at TCCN. It’s the Chain tensioner inside the engine. You need to take the front cover off in order to replace and if you’re going to do that then might as well take care of all the other stuff that usually happens in our engines. Which is the valley plate seal the camper seal the front cover seal, obviously , and replacing the tensioners. AMD has told me that he has never seen a tensioner outright cause engine damage because it’s not working for properly. It’s just an annoying ticking sound that you’re going to hear if you pay attention to it. Trust me the noise didn’t just start because you changed the oil. It was there slowly getting worse and worse and it’ll slowly get louder and louder. You will especially hear it when it’s cold. You probably just didn’t really notice it until now, you were probably at a drive-through and had your window open and heard it that way, which is how I first heard it, obsessing over it for a little while we pretty much figured out. That’s what it is. Here is a video we did where we ended up doing this fix on a tundra which has the same engine as ours. Go to 16:05

I assume you own the white GX? Question thats on my mind, is that this ticking noise happens on new motors sometimes right after the first oc, is this something TCCN and his own GX suffers from, and should owners proactively bring this up to the attention before the powertrain warranty is up as a defect?
 
I can’t say that I’ve heard it on AMD‘s GX, but that actually gives me idea to see if I can hear it or not. If you really pay attention and you’re driving fast next to like a half wall along the highway you can actually still hear the ticking so it’s not just a thing that you can hear when you’re going slow. It’s just that you can hear it more easily in that situation. Only solution is to replace the tensioner, simply have it done when you eventually need to take the front cover off for any of the other reasons the GX needs to remove the front cover. I wouldn’t stress over it because it’s not gonna damage your engine.

Cold starts, driving in town with parked cars, i can hear it. I just turn off all hvac and accessories to hear just the powertrain. I dont really know a proper way to broach this topic with the service depo or counter their probable, its normal.
