Question
Hi Robert, I just bought this car, has been sitting in garage since 1987, looks to be in very good condition overall. Unfortunately I don't know where to start to get it running. Previous owner told me car was running when he put it in garage. I know I should change the oil, what type of oil should I put in it? Same thing with wires and spark plugs? I can't wait to hear this car running, I don't want to mess it up, Help??? I would appreciate any suggestions, Thank You!!!

Answer
Hello Benny,

"Waking up" a car that has been sitting for a long time requires careful actions:

1) Check to make sure the engine turns freely, With the car in neutral, tighten the fan belt with your hand and attempt to turn it over. If it moves, great sign. No, be careful to repeat step 2 until the engine loosens (hopefully)

2) Pull all the plugs, labeling the wires so you can reattach correctly. Put a couple of tablespoons worth of "Marvel Mystery Oil" (available at Walmart, etc.) in each spark plug hole. Let it soak a few days minimum before you attempt starting

3) Replace all plugs, points, condenser, distributor cap and rotor with new. NAPA has listings for these old cars but other auto parts stores should be able to help you also

4) Drain oil and replace oil filter (if it has one). Refill with straight 30 weight Shell Rotella motor oil. While Rotella is formulated for todays' diesel engines, it also most closely replicates the oil of years ago and is best for these old engines.

5) Drain the fuel tank (should be a drain plug in the bottom) and check the fuel lines for blockage, fuel gum, etc. If the lines or tank seem excessively dirty, disconnect the incoming fuel line at the fuel pump. Disconnect the fuel like at the carb, blow out and inspect; If this is the case, you'll need a small gas can and fuel hose to connect to the fuel pump so you can start the car with fresh gas

6) Once your engine is free, install all your plugs and electrical components, add fresh 6 volt battery, add fresh oil--you're almost ready to start!

7) Check radiator and hoses for coolant and blockage. Clean, replace and/or add coolant as necessary

7) Pour half a teacup sized portion of fuel directly down the throat of the carb.--this will help the car start with a minimum of cranking--set the choke butterfly closed and

8) Put the car into an area with good ventilation--it's going to to produce a lot of smoke initially as the top oil and funk of the years burns off.

9) Make sure the Key's turned all the way to the start position and hit the starter button--You're hopefully in business!!!

This procedure is good for getting a non-running car started. Before you get on the road, you need to check engine tune, charging system, gauges, tires, brakes, front end and transmission for leaks, rot and operation. If you get stuck, make the acquaintance of your local chapter of the Vintage Chevy club. Help, advice even assistance may be had from this fine group.

Good luck--Chevy 216/235 engines are tough and hard to kill. Give them half a chance and they'll run and last practically forever!
