Whine noise coming from engine when accelerating
When i accelerate there is a whine noise coming from the engine. it seems to be louder when he engine is cold. Is this a belt that needs to be changed or something? I know there isnt a timing belt so is there something else causing this?

i think thats normal man, i've heard all 350s sounds like that. mine sounds like a supercharger too and i love it. its actually pretty loud before 4000rpm and when engine is cold. someone told me its because of the direct injection technology that toyota uses but don't quote me on that. whatever it is i like it

it could be that a cat has made a home out of your hood compartment too. many times cats will crawl up underneath the hood while your car is parked since it's usually warm, especially if you frequently park outside.
do you park your car in a garage or are you outside somewhere usually?
The best solution is to leave some cat food on one of the plastic parts near the engine (so the food doesn't just burn up on the engine) so the cat isn't hungry and thus won't whine and meow while you're driving. he's just hungry.

It's the timing chain that the IS350's use as opposed to the quiet timing belt that majority of cars use. The timing chain doesn't require replacing which is why Lexus went with it. They sacrificed noise for no replacement requirement which I don't like. The whine annoys the crap out of me.

To the OP, I vote for belt or vaccum leak. Belt is cheaper, and as a maintenance item should be done first.

hmm so what would be the symptoms of a bad belt or vaccum leak? cause i still think its normal but i am not sure now. i haven't notice any power loss or issues like that but may be i got used to the power. i am taking my car for a service on friday and i will tell them about the whine noise and see what they say. but if they fix it and i dont hear the whine i'll be pissed man i love that sound. all my friends think i have a supercharger installed

wow oh wow, have you ever heard the noise of a timing chain? It is more of a rattle than a whine. Timing chains are also more costly and heavy in an engine, that is why a lot of manufacturers switched to belts, to save money, but then, you are stuck with big maintenance bill at around 100k. Mostly labour, so the dealer network is happy too.

edit: and I don't know if you're trying to say I'm wrong about our cars having a timing chain but if you are then you my friend are the one that is wrong.
