I've had my 330i for 3 months, during cold temperatures (as low as 10 degrees F.). I have never heard any valve noise, or "rattly and spitty" sounds coming from my 3.0L. Also, I don't think the 3-series engines have Valvetronic, although they do have Double VANOS. I just recently read that the new E90 3.0L will have Valvetronic.
