2003 G35 started this in the morning when it was cold out. Changed the oil and filter as it was getting low. This car has had oil leak problems. Sounds like a problem with the valve system.
Maybe it's not the lifters and it's the oil pump. As the car was idling the noise quieted down (until we gently revved the engine) - then it got louder.
This was caused by a single variable-valve tuning solenoid - one of two on the engine. It was about 450 dollars with labor to have it replaced.
