Collapsed lifter, plugged lifter oil channel, timing, bent valve, could be bunch of things.
Make sure you check your timing belt and tentioners, I had a car once where the timing bet slipped and it bent a valve and it made that noise. Long story short I pulled the top end apart to check the lifters thinking one was bad, found nothing wrong, put it all back together and on the first start up my tentioner went out all the way bending every valve in the motor.
