Car sounds crappy for first 10min

[Alesen]

Ok, my car runs fine, but after start-up every morning, or after it has been sitting for 3+ hrs it sounds like crap, like weird valve noise or w/e. Not noticeable outside but you can definitely hear it inside.

I thought it was because of the cold, but now its getting warmer it still makes that noise. I have 56k on it so I guess its still covered under warranty, anyone know a quick fix or how to get dealer to shell out $$ to fix the noise?

Oh I have a 2007 Avalon Touring.

It sounds like you just need to let your car warm up before taking off.
