I am interested in hearing about long term (2-3 years) storage of an engine in a car.

I will be relocating to South Korea, but my GTO and Avalanche will sit in the garage stateside. What are some good tricks to prevent corrosion and rust within the engine while I am gone?

Thanks!

The amount of money you will loose on depreciation with both those cars I would sell them. I understand that may be a wash on the GTO with the mods you would loose money on selling now so it could be a toss-up on that one. The Avalanche should go though.

Do an internet search on car storage. I have not stored a car that long but a few things come to mind. Remove the batteries completely from the car and I would probably dispose of them by giving them away or taking them to a recycling center. I would not leave batteries that long on a trickle charger unattended. Add fuel stabilizer and fill the tanks completely full. Drive the vehicle a short distance to get the stabilizer throughout the entire system. Upon return from Korea I would drain and discard the fuel. The main reason for the full tanks is to eliminate condensation from forming in the tanks. Get several desicant (sp?) bags and throw them in the interior along with some moth balls. The bags absorb moisture and the moth balls help keep out rodents which love stored cars for homes. I would also put moth balls in the engine compartment and trunk. Wash the vehicle and allow it to COMPLETELY dry and then put a ligth weight car cover on the car. Big debate about jacking the car and leaving it on blocks. Some say no reason with radial tires. Some say to jack car and remove the wheels so that the shocks are not fully extended which may cause corrosion on the exposed shock parts. Some say only jack the car up a little to take some of the weight off the suspension. Who knows on this one? I have also heard not to shut the doors completely ony the first catch so that the weather stripping is not fully compressed.

Neither one of these cars is a classic collectible but do have intangible value to you. Nevertheless the best thing financially for you to do is to sell them and put the money in the bank or Cd's and buy what you want when you get back.

By the way I applaud you for your service and thank you and your brothers in harms way everyday. :angel:

Sounds like some good advice there ^

Gee, that wasn't really what I was expecting to hear. I was actually after ways to coat the insides of the cylinder walls to prevent rusting. But, I suppose I can ask GMAC what my Smart-Buy options are given the orders. I would like to keep the GTO because I do have so much invested in it, but the truck I can give up because it is next to stock. Besides, when I return there may be an electric hybrid version of it. I actually like the truck more than the car because it has so much utility, but the GTO is a thrill to drive. The military has me deployed so much than neither vehicle has many miles accumulated.

The cylinder bores or liners shouldn't really rust if the engine is buttoned up good. I would put fresh oil in the motors and run the cars while getting the fuel stabilizer in the whole system. I would remove the spark plugs and spray either WD-40 or a higher viscosity motor oil into the bores. How much??? I don't know. I have only read about this procedure and have not done it myself. I would lean towards the motor oil vs. the WD-40. While the plugs are still out I would use a breaker bar on the crank and hand crank the engine over a few revolutions to get the oil on the cylinders. I recommend a higher vis oil so that is sticks and coats the bores better than a thinner oil. I would also use a dino oil vs. synthetic. Like I said before I have only read about doing this. This just seems like common sense approach.

However my primary recommendation is to sell or return the truck. If possible I would return the Goat to stock and sell it. Then just store your built motor for a future use.

Oh one other thing - drain and flush the coolant in both cars. Put in fresh coolant. Again corrosion prevention.
