I've read on forums that some people recommend certain steps for taking a car out of long term storage e.g. Pull plugs and lubricate cylinders, and then manually crank the engine. They say it is to cycle the system oil, and prevent scoring the cylinder walls. I have a flat 4 turbo engine with 31k miles on it in storage for 13 months. It's not very easy to access the cylinders and I have limited tools since the vehicle is at a storage unit a few miles away. I did plan to manually turn the engine but not pull the plugs. Is it really necessary to perform these steps?
