Question Can Seizing / Locking Up be Avoided

I have an 88 Turbo II that has been setting for 7 years or so. Want to get back to it--have not tried to start it. Anything you recommend I do (other than draining/refilling gas, oil change and charge battery) before starting to avoid locking it up? Or is it better to see if it will start up and if not, work backwards from that point?

Start by pouring an Oz of marvel mystery oil into the trailing spark holes using a length of vinyl tube, and cranking it over by hand with a socket. Do this every two days for at least a week before attempting to crank.
ive got two engines, one that sat for 13years, and one that sat for 10 years. Both freed up easily using this method, and the MMO helped clean off the carbon and soften it. I know this because I tore one of the motors down to rebuild.

i like to try and start it, and then go from there. you do need to look the thing over first though. basically you're starting the car to see if the engine is good, once it is, then you change all the fluids/filters/etc. if you had a good set of spark plugs on hand its nice.

1. make sure there is oil, and coolant. add as needed
2. you can certainly put oil in the spark plug holes, i never do, but i do crank the engine over by hand, just to make sure it spins freely.
3. you'll want to put a battery in, and jump the fuel pump, to see if it runs. if yes, keep going, if no, you get to find out why
4. disconnect the fuel pump and CAS, i remove the spark plugs, crank until you have oil pressure.
5. put it back together an see if it runs. if no, then you get to circle back and find out why, even with really bad gas, it should start and run, although probably not well.

once it runs, and the engine isn't bad, then you will want to warm it up, and change the oil, and coolant, and the brakes are probably dead, and so are the tires, etc etc
