06 RAV4 I-4, noisey tappets?

Coming up on the 35k scheduled maintenance and I'm thinking of letting the dealer do the oil & filter change and check out a few things before the bumper to bumper expires at 36K.
I've only three concerns I'd like checked out.
1) Floppy drivers side visor.
2) re-flash the ECM. (intermittently hessitates on cold exceleration w/AC on).
3) check out what I consider to be somewhat loud tappet-like noise at idle.
I noticed what I consider to be somwwhat loud tappet noise since new but thought it would go away with breakin. It hasn't.
I mainly only notice it after it's warmed up and either idling in the garage or when next to a solid wall like at the drive through window at a fast food resturant.
The engine has plenty of power and makes no unusual sounds at higher rpm, only at idle in confined spaces.
I do my own scheduled maintenance every 5K miles and use OEM oil filters and Mobile 1 5w20 oil.
In any case, this could be normal for these engines but I'm not sure.
Does anyone else hear a slight tapping-like noise in their I4 engine at idle under similar conditions?

Believe it or not, this might be normal engine noise. especially seeing as how you said it was like that since you bought it. the 2AZ-FE 4-cyl is a somewhat noisey engine, along with the 1GR-FE V6 out of the tacoma's.

my tip for you is when you go to have the dealer look at it, DONT TELL THEM IT WAS LIKE THAT SINCE YOU BOUGHT IT, because they wont even look at it and just assume that its normal engine noise. go in there and tell them that you just noticed it, that way they actually take a look at it.

Thanks again The Drifter.
I'm also thinking that it's just normal engine noise. The engine runs too good and to tell you the truth, I've finally evolved into one of those "don't fix it if it's not broke" individuals now and amazingly my machinery lasts alot longer now.
Did a little more research and it agrees that these engines can be alittle noisey at idle and that this is SOP. I also looked into what it would take to adjust the valves and it is somewhat of a major operation, involving removal of the cam(s) and sizing up the correct size special shims. Theres also a dampner in the mix that act's somewhat like a hydraulic lifter but doesn't directly contact the valve. In any case, I may mention for the dealer to listen to make sure it's normal and I'm pretty sure they'll come back saying it's fine.

I thought the Toyota Tick is what they call the bloodsucking dealers.

Bump... I too believe my I4 is getting really noisy. Recently took it to dealer to have tsb on idler pulley performed; the noise was not related at all to the engine noise ive been hearing for the past 4-5 months. I thnk its tappet noise or engine pinging, either case its excessive and getting worse. Will once try techron bottle and chevron premium gas. Must admit since it was new i used gas from sheets gas stations in PA, but currently using shell since april this year. Could be carbon buildup contributing to the pinging???

Chevron premium and bottle of techron concentrate did the trick... It was pinging even under shell premium, not sure if chevron or techron concentrate or both solved the pinging, but at least i was able to identify its related to pinging.

High test is unnecessary based on pcm programming for the timing curve, something else must be happeneing here, the Techron will clean the injectors and to some extnent the intake valves, but high test should not be necessary.
