Does yours...uh...PURR?
I'm probably just a typical paranoid new car owner, but I could swear the motor has gotten noisier since I got the car (750 miles)
Are these just clattery little engines? I can hear valves chattering away at idle, enough that a friend of my mine commented that it sounds a bit like my old diesel Volkswagen!
I don't mind at all if it's normal and not a sign of anything wrong. The car runs great otherwise. The only issue I've noticed is a wavering idle sometimes, when the car is first started. It can be just a little slow to start and every now and then the tach needle will dip like it's going to stall. Not that often though.
So? Thoughts? Comments? Does your sound like a purring cat too, or is my valvetrain eating itself or something?
Talk to me mah brothas

No worries
No worries man. Mine does the same. One thing I have noticed is that gas makes a huge difference. I used Shell at first because it was cheapest near my house, and I started noticing a slight knocking noise when idling (the manual even mentions this and says a slight knock is normal) but it bugged the hell out of me. I even tried Shell's super "flavor" and it knocked just as bad. I was getting ready to take my car to the dealer and see what he thought but decided to give it one last chance with different gas. I filled up at exxon and she's been running smooth since! I've also read in posts that using sinthetic oil helps but I've yet to need my first oil change so we'll see. -later

I think the tapping it the valve acutally, but a noisy valvetrain doesn't always mean trouble. Different types make different noises depending on how valves are actuated.
The whine is the timing chain, if you're talking about what I think you are. Chains are a little noisy but I will take one over a belt anyday. I was psyched when I heard these have a chain. Belts break. When a T-belt breaks in a high compression engine like this you're in some deep ish. You think your valves are noisy now, imagine what they'd sound like crashing into the top of the pistons at 94985970893 miles an hour
Luckily, unlike the othe 90% of the cars on the road we never have to worry about that rare but catrostrophic event. We also don't get the biggest regular maintance buttraping there is with any car--- replacing the timing belt.
Our Scion's will be on their third or fourth owners and we'll be driving hydrogen fuel cell powered plastic cars that go 0-60 in 30 seconds by the time that chain needs replacing.

Glad you mentioned this. I have the same loud valves. I noticed a knocking/rattling from the engine when I'd accelerate from a stop and I freaked. I posted about it under maintenance/problems, but made the mistake of describing the problem as a rattle, and got suggestions on how to make my hood stop rattling. I took it in to the dealer, and about three different guys took turns pretending not to hear the sound at all. Finally, it was "OH! THAT sound! That's normal." I'm pretty sure they were ____ting me and had no idea what the sound was, as it's much more pronounced from inside the car and when the engine's warm. I haven't had a chance to try a different gas, but you better believe I'm hitting Exxon next time.

Mines got just over 1000 miles on it (in less then two weeks ) and it's doing it too.
Going to do an oil change tomorrow, going to either buy the ground wire set, or just make my own (wouldn't be hard, plus I can find some color matched 4guage wire). Hopefully this will quiet things down some.
