What is the proper way to start a 1969 chevy that may have been sitting for 10+ years?

I'm looking at this 1969 Chevy El Camino, but it's been garaged for possibly 10+ years maybe even 20. I was on the fence about trying to have them start it because I was wondering if there was a proper way to lubricate everything since its been sitting and drying out for so long. Anything I should do prior to starting for the first time please let me know, thank you.|||It's gonna take some work, time and money to fire it up right with out damage. Not worth it for something your just looking at..





Buy the car not running if you like and want it, then try to start it at your place.





Drain oil and put new in, change oil filter


Change fuel filter


Remove all spark plugs and squirt some marvel oil into every cyl through plug hole.


Use a breaker bar and 5/8" socket on center bolt of crank and try to turn it by hand.. If it it turns.. Good, if not don't force it. Put some more marvel oil in and let it sit a couple days and try again.





Once it turns free by hand, then you can move on.





Put a new battery in the car





Check to see if theres fuel in the tank.. If it wasnt not drained before being stored, then the tank and pickup will be gummed up and rusted.. By pass the tank at this point just to see if it will fire..





Pull fuel line off the fuel pump and run you a lenght of rubber fuel hose from pump to a 2, 3, 5 gallon gas can.





Remove the dizzy, and use an oil pump primer tool and a 1/2" drill to turn oil pump untill you get oil pressure (this can take 5 to 10 min of spinning the pump at full speed wit drill)





Then re install dizzy (set timing right)


Put in new points


Put in brand new spark plugs





Pour alittle fuel down the carb





Put a couple of gallons in your can





Now try to crank it up





If it runs, bring RPM up to 2,000 RPM and keep it moving from 2,000-3,000 rpm for about 5 min





Then you can shut it down, and try hooking your fuel supply line from tank back up to pump and put some fuel in tank and see if it will pull through the pickup





If not you will have to drop tank, has it pressued cleaned and maybe put in a new pickup sender|||the gas is bad after ten years. purge all fuel. add fuel dryer. add fuel. drop float bowl. clean. oil and filter change. fresh tune up. pull lead off the coil. little oil in the cyls. turn engine over w/o spark till the oil light goes out. connect coil. start. keep rpm low if possible. listen for lifter tick. those may need to be pulled, serviced to remove oil ridges. keep an eye out on the temp. t-stats get stuck to.

likely the valve guide seals are dry and cracked. if she puffs blue smoke after some good warming and she passes comp/leak down test, likely the guide seals or an oil ring collapse.

check condition of t-chain. pull dist cap. rock crank. rotor should report instantly. any degree of movement by the crank w/o the rotor turning instantly means the t-chain is in need of servicing. 1 or 2 degrees of movement on the crank will let it start. much more than that and she may not. i've seen 10 degrees movement and still start. wont run worth a sh*t. but start.

there's gonna be a little bad fuel still in the carb after float bowl cleaning unless you rebuilt it. so get some ether. that will help it run till the motor sucks that out.|||I am only a back-yard DIY wrench, but folks tell me that turning the oil pump with a drill motor to get the oil circulated up and around the bearings and valves, etc is the first thing to do. Whatever you do, crank the engine with the main coil wire to the distributor disconnected=no spark to engine. Some folks pour a LITTLE oil on the valve springs (if you can get to them) The important thing is OIL, OIL, OIL!





And check the gas in the tank; might want to unscrew the fuel line AND PLUG IT, and use a can to fill the carb or buy one that has the adaptor that connects to the carb in place of the disconnected fuel line.|||You have to hand crank the motor to see if it's frozen.



Change the oil and squirt some into the cylinder(through the spark plug hole) then try to hand crank it.



If that went well then new gasoline, coolant, and battery to see it will start.
