Timing Chain Clatter?
I just changed the oil in my 2007 RX 350. I messed up and let my funnel overflow and some oil ran down the front of the engine cover and came out underneath where the oil filter cover is. No big deal I thought.
Upon startup, when I rev the engine, I now hear what I can only describe as a clatter from that side of the engine. It only occurs at rpm's over 1200 or so, so it sounds normal it idle.
Did I get oil on the timing chain or an accessory belt and this is causing this? I listened under the hood while the wife revved the engine and to me it was coming from the area where I spilled the oil.
Anyone have any ideas how to fix this, or should the noise disappear on its own?

you dont have a timing chain, you have a belt.
oil wont cause this, its probably coincidental. more than likely its you heat shield coming loose. have your wife rev the engine and push on some heat shields (wear gloves, its gets hot). once found, remove, no need to replace.

Did more investigating by popping off the fuse/power steering reservoir cover. I definitely got some oil on the accessory belt. I assume the oil won't hurt it and the noise will eventually go away?
Kiwi, I thought one advantage of the 3.5 in the 2007+ was the adoption of a timing chain that requires no maintenance. In fact, I'm certain the 07+ RX 350 has a timing chain, not a belt.

You dripped oil on your ACC belts, not any of the timing belt (chain), right?

It should evaporate in due time. If they were not really soaked, they should be good after a few days of driving.
Somebody sugegsted spraying WD40 on belts...I do not know if I will recommend this though.

It has a chain. The chain is inside the engine, not outside like a belt. As such, it's already in oil, and there's no way you could have got oil on it. There's also no way you'll every have to pay $600 for a timing belt change, which is a good thing.

Thanks for the info about the chain being inside the engine. I am almost positive I got some oil on the accessory belt, it was still "chirping" this evening. Hopefully it fixes itself after the oil disperses and wears off.

I've alway wondered how they come up with the 'flat rate' times.
Do they give a chimpanzee imperial sized tools to work on a metric sized vehicle, blindfold it, handcuff it, and then time it? This becomes the flat rate?
I mean, you did two in four hours and I know lots of mechanics / dealerships that can get stuff done faster than the flat rate time.
