This year when I pulled my car out of storage I too experienced lifer noise when I started it up that lasted quite a while, 3-5 minutes, but it hasn't returned since. This was the third winter I stored it and I never experienced the noise on startup any of the previous years when I brought it out of storage. Since last winter was the only winter I never started the car, previous years I would start it once a month and let it run until it came up to temperature, I am suspecting that because of the viscosity of the 0-40W oil that the lifters became dry sitting. Next year I am going to start the engine once a month and see if that prevents the lifter noise from reoccurring.
