The allure of a barn find is undeniable. The thrill of uncovering a forgotten classic, untouched for decades, is a powerful draw for car enthusiasts. But starting a barn find after years (or even decades) of slumber requires careful planning, patience, and a bit of mechanical know-how. The key is to proceed cautiously, assess the situation thoroughly, and prioritize preservation over immediate gratification.
How do you start a barn find? The most crucial first step is a comprehensive assessment of the vehicle’s condition. This involves a visual inspection of the engine, fluids, tires, electrical system, fuel system, and overall structural integrity. Before even thinking about turning the key, focus on preservation: carefully remove any debris, stabilize rust, and lubricate moving parts. Then, proceed with a meticulous, step-by-step approach to coax the engine back to life, prioritizing safety and minimizing potential damage.
Initial Assessment and Preparation
Before you even dream of hearing that engine roar, you need to understand exactly what you’re dealing with. This isn’t just about whether it’s a Mustang or a Model T; it’s about the state of its individual components.
Visual Inspection: The First Line of Defense
Begin with a thorough visual inspection. Document everything with photos and notes. Look for the following:
- Rust: Assess the extent of rust damage, both surface rust and structural corrosion. Pay close attention to the frame, floor pans, rocker panels, and any areas prone to water accumulation.
- Tire Condition: Are the tires dry-rotted, cracked, or completely flat? Consider them unsafe for even short distances until replaced.
- Fluid Levels: Check all fluid levels (oil, coolant, brake fluid, power steering fluid, transmission fluid). Note the color, consistency, and odor of each. Low or contaminated fluids can indicate serious problems.
- Wiring: Inspect the wiring harness for damage, rodent chewing, cracked insulation, and loose connections.
- Interior: Assess the condition of the upholstery, dashboard, and other interior components. Mold, mildew, and rodent damage are common in barn finds.
- Mechanical Components: Look for obvious damage to the engine, transmission, differential, suspension, and brake system.
Prioritizing Preservation: Stabilize and Protect
Your initial goal shouldn’t be starting the car, but preserving its current state. This means:
- Cleaning: Carefully remove any debris, dirt, and rodent nests from the engine compartment, interior, and undercarriage. Use a soft brush, vacuum, and mild cleaning solutions. Avoid high-pressure washing, which can force water into sensitive areas.
- Rust Treatment: Treat surface rust with a rust converter to prevent further corrosion. Consider applying a protective coating to exposed metal surfaces.
- Lubrication: Lubricate moving parts, such as hinges, latches, and linkages, with penetrating oil.
- Rodent Prevention: Take measures to prevent further rodent infestation. Set traps or use repellents.
- Documentation: Photograph everything! This is crucial for insurance purposes and to document the restoration process.
Reviving the Engine: A Step-by-Step Approach
Bringing a dormant engine back to life is a delicate process. Rushing it can lead to costly repairs or even permanent damage.
Pre-Start Checks: Ensuring Safety
Before attempting to start the engine, perform the following checks:
- Oil: Change the oil and filter. Use a high-detergent oil specifically designed for older engines.
- Coolant: If the coolant is old or contaminated, drain and flush the system. Refill with fresh coolant.
- Fuel System: This is often the most problematic area. Drain the old fuel from the tank and fuel lines. Inspect the fuel tank for rust and debris. Consider replacing the fuel filter and cleaning the carburetor or fuel injectors.
- Spark Plugs: Remove the spark plugs and inspect them for fouling, damage, or excessive wear. Consider replacing them.
- Crank the Engine Manually: Before attempting to start the engine with the starter motor, try cranking it manually with a wrench on the crankshaft pulley. This will help lubricate the cylinders and ensure that the engine is not seized.
- Check for Spark: Once the engine turns freely, check for spark at the spark plugs. If there is no spark, troubleshoot the ignition system (coil, distributor, ignition module).
The First Start: Patience is Key
If all pre-start checks are satisfactory, you can attempt to start the engine.
- Prime the Carburetor (if applicable): Pour a small amount of fresh fuel directly into the carburetor throat.
- Attempt to Start: Crank the engine for short bursts (5-10 seconds) to avoid overheating the starter motor. Listen for any unusual noises.
- Monitor Oil Pressure: Watch the oil pressure gauge (if equipped) or check the oil pressure manually with a gauge.
- Adjust Timing (if necessary): If the engine starts but runs poorly, adjust the ignition timing.
- Run the Engine Briefly: Once the engine is running smoothly, let it idle for a few minutes. Monitor the temperature gauge and listen for any unusual noises.
Frequently Asked Questions (FAQs) about Barn Finds
Here are some frequently asked questions to provide additional valuable information for those embarking on the journey of reviving a barn find:
1. What are the best tools to have on hand when starting a barn find?
A well-stocked toolbox is essential. Include penetrating oil, a breaker bar, sockets, wrenches, screwdrivers, pliers, a multimeter, a compression tester, a fuel pressure gauge, and various cleaning supplies. A good shop manual for the specific vehicle is invaluable.
2. How do I deal with a seized engine in a barn find?
Penetrating oil is your friend. Pour it into the cylinders through the spark plug holes and let it soak for several days or even weeks. Gently try to turn the crankshaft pulley with a wrench. Avoid forcing it, which could damage internal components. Consider removing the cylinder head to inspect the cylinders and pistons.
3. What should I do if the fuel tank is heavily rusted?
Severe rust requires professional cleaning or replacement. A radiator shop can often clean and seal a rusted fuel tank. If the rust is too extensive, replace the tank with a new or used one.
