I've been overseas for 7 years. My 81 jeep CJ-7 was runnig fine before I left. All I did was lift it off the tires and have it resting on some concrete blocks all this time. I did not drain anyhting but the fuel system, but not at the stock carb. Now I want to make sure before I start it up, I correctly check/replace things so I don't damage anyhting. Recommendations before I turn the key?

take spark plugs out put little ATF in each cylinder let it sit overnight incase the rings are seized, change oil, make sure tank dosen't have bunch of water from condinsation, change fuel filter. check air filter make sure mice didn't get at it. cranks slowly by hand make sure the rings are free (after letting sit in W/ATF) use a break bar and socket. you should be fine.

Thanks for responding so quickly. I'm not to bad at figuring a few of your comments out, but I do need a bit of hand holding on this.
1. is ATF, automatic transmission fluid.
1. Is a breaker-bar a metal rod I slide over my socket wrench to give me more torque, I assume?
2. Crank it by hand? Would I attach a socket to the pull wheel at the bottom of the engine, then using the breaker-bar, I'd be able to turn the crank so the pistons pump?
3. Should the jeep be in neutral. Seems like it should be to rotate the crank easier.
4. Do you think I need to change any of the fluids out [gear oil, motor oil].
5. Lets say, I follow execute all this, and the next day the engine start fine. Do you think I can just assume it's pretty drive-able at this point or should I start looking for any signs of something that it is simply deteriorated over time [i.e. seals, gaskets].
6. I've not seen any oil dripping from underneath the jeep anywhere. I have heard that seals and gaskets easily rip open when a car sit for a long time due to a lack of lubrication. Any comments on this?
Thanks again.

1.ATF = auto trans fluid
2. yes, 1/2" breaker bar with the appropriate sized socket to fit on the crank bold so you can turn the engine by hand.
3. should be in nutral and wheels blocked so vechical dont roll (if wheels are back on the ground)
4.yes I would change to oil, filter and check axles for signs of water (milky color)
5.well let it run keep eye on oil pressure, temp and all your gauges make sure its running good. Your break rotors and or pads could be rotton may not stop the greatest if it was stored out side. Check break lines make sure they are not rotton/leaking. I would be very carful and slow lots of things could go wrong with a vechical that has been setting for a long period of time. dont take risks if you feel it's unsafe to drive dont.
6.Gaskets can dry out from engine not running in a long time you'll have to get it running first and see if anything leaks.
Best of luck .. p.s. crank the engine while the plugs are out so you are not fighting compression.
