Thank you for allowing me to assist you, my name is Joe and I will be happy to assist you with your concern today.

You're going to want to check everything over just the same as anything else.

A car that has set for that long is generally going to be one that needs some level of restoration.

I highly suggest that the engine is not attempted to be turned over without checking fluids, changing the oil and putting some fogging oil down each cylinder and first turning engine a few times by hands to ensure lubrication.

Rust and corrosion will be things to also check for under the car.

A car of this type I would also be checking body for previous repairs of damage and that everything lines up.

Run engine casting number to make sure it matches.

Fuel might just need to be drained and changed, might need mild cleaning or may have caused major issues, you will want to open fuel system and inspect.

A car sitting that long will also generally have dry gaskets/seals that once started and used will form leaks.

Thank you!
- Joe

Hey Joe thanks again! Are you familiar with grand nationals ? I'm curious if there is anything particular I should do do, I know these cars are tricky with the turbos. I've heard to check the vacuum lines as well and to run a certain engine oil that has zinc additive in it. Is that true? I've had the car for almost 10 years in my parents garage and they finally let me clean the garage out and take the car to place. The motor was rebuilt before the car was parked with maybe 300 miles on it and 42k on the chassis. I'm guessing besides the things specific to the car I should do all that you said. I'm guessing probably go thru all the fuel lines as well? Tank, fuel filter, etc?
