Landcruiser storage info
Below is a quote from Ben Barnes, who builds Busch engines here in NC, regarding how to store an engine that's going to sit for the off season:
"Crank the engine up and get it to normal operating temperature," says Barnes. "Then take some lightweight oil, 10 weight or something of that nature, and pour it in the carburetor with the motor running. Pour it in until the engine starts smoking out the exhaust real good, and then shut the engine off. What that does is it lubricates the cylinder walls and the rings to where it doesn't rust over the winter.
"If the motor is real dry, it will create some rust in the cylinders. If you get oil on those cylinder walls, they will not rust. When you put a new set of spark plugs in it in the springtime and crank it up, let it run slow and it will burn all that oil out of there, and you're ready to go.
Mouse poison in the glove box and strategically placed around the cab floor and under the hood.
Also, put some hardware cloth over the exhaust pipe. Keeps the mice/chipmunks from nesting in there.
run some sta-bil through the fuel system, it's preferred that it sit on jack stands, either drain antifreeze or make sure you have it tested to well below what you expect. pull battery and put on a trickle charge (if possible). make sure it's clean inside and out, wax it if possible, cover with a soft car cover that's breathable, leave at least one window cracked slightly. drain oil.
