Questinable Conditions
I would not be too concerned about long term outside storage of and engine in the car. If there was a pre-existing break down (spun bearings, scored crank, broke rods, holed pistons etc etc...) that is manageable ..... as for BIG PROBLEMS just from sitting for a long time .... NO SWEAT you can count on soft lines (fuel lines), vacuum hoses, serpentine belt, rad hoses to be DONE, and probably the injectors, fuel rail, fuel lines and pump will be plugged /gummed up with gas gone to "varnish". Thats manageable.
Pull out the spark plugs, pour lots of light weight oil into the plug holes, and let it sit overnight. Leave out the plugs and crank the engine over by hand (big socket on crank snout nut, or if the serp. belt is okay, use a big socket on the alternator pulley nut its the easiest to get at). If it turns over manually, leave plugs out, disconnect the coil/ign module harness and spin the engine over on the starter motor (prolly gonna need a new battery) That should remove the surplus oil.
If all goes well to that point, then stick in the plugs hook up the ign. and try for fire in the holes. If you get spark but no running engine then the gooed up fuel in the injectors etc. is next order of business.
Seen insides of lots of engines and rears left outside (wrecking yard babies) with no protection whatsoever. Insides look like new. Oil embeds itself real well into cast iron and bearing surfaces.
