ticking engine
I'm not sure if I've just gotten used to the sound of the car or what but lately, it seems like the engine is ticking pretty loudly. It runs perfectly and I didn't think much of it until my friend commented on it. Sounds like it is coming from the drivers side (mainly).
Anyone else notice their engine ticking and if so (or not), any insight as to what the problem might be?

Does it ticks all the time ?,or only at cold start ?, or after warm up ?,does the tick increase w/ engine speed?
my 04 does that only at idle after warm up, had Lexus tech checked out, he said that is valve train noise, no harm to engine, and suggest that i can do the WT adjustment at 90K service, (currently 67K).
I change oil use to Penz oil syn Platium 5w30, the ticking went away !,all quiet now.
I previously used QS 10w-30 syn blend,Napa full syn 5-30,and other regular, and all ticked after warm up, not on cold start though.
Not sure we are talking about the same thing (ticking).

Do you think that would have been enough to cause a leak in the exhaust manifold/gasket?
How loud was your ticking? was it just noticeable or really loud (mine is kind of in the middle). as far as I can tell, it is only at idle and the engine runs like a top so I don't know what to think/do.

2 seconds at red line should not cause problem,especially your car is running fine, don't know much about the exhaust manifold leak.
But the owner manual does mentions the valve train noise ,and call for inspection of it (VT noise) on 60k or 90k service.
my gx's ticking is not noticeable when siting inside the car w/ car running, but standing outside I can hear it clearly, not very loud, like "tag tag tag tag .....".Again, it only does that on idle after warm up, give it some gas,the noise disappears.
The VT noise must be common on GX (at least on the early 03 and 04),that is why it's mentioned in the owner manual.the Lexus tech assured me my gx's engine is still very strong,nothing to worry about. and it runs great.

Just found this in the manual "Inspect for excessive lifter noise and engine vibration
and adjust if necessary. A qualified technician should perform this operation.".
This seems like a pretty big job...or is it? You just need to remove the valve covers right? I guess your gaskets get changed which is good too.
Anyone ever attempt this or have any info on how to do it? I noticed the clearances are listed in the manual as well. Suppose I could be 100% sure it is not the exhaust before attempting this.

I am glad I am not the only one, mine ticks too. Its coming from right side under the glove compartment. First I thought it was AC compressor (because it started when my AC was one). It only ticks when the car is in motion. It would be interesting to find out what Mann777 thinks about this.

Wow, you guys want to make me start mine up and listen. If you have a friend, with the hood open, and the engine running at start up, have them put a rag, or other, over the exhaust pipe for a couple of seconds. If it is an exhaust gasket leak, it will be louder (more back pressure).
If the noise goes away after about two or three minutes, sounds like valve trane. It is colder now and you may have some higher mileage? Not sure I would worry about it, if it goes away after warm up.
I run synethic, 5 w 30 Toyota/ Mobil 1. I usually on cold days, let it run for a full minute or more, before putting it in gear. Summer, about 30 seconds.
