2. Preparing Your Small Block Chevy for Valve Adjustment
Safety first! Before beginning any work on your engine, disconnect the negative battery terminal. This prevents accidental short circuits.
Preparing the Engine:
- Consult your owner’s manual: Find the correct specifications for valve lash (clearance) for your specific Small Block Chevy engine. These specifications vary depending on the year, model, and modifications.
- Warm-up the engine: Run the engine until it reaches normal operating temperature. This helps to ensure accurate valve lash measurements.
- Securely position the vehicle: Use jack stands to securely lift and support your vehicle. Never work under a vehicle supported only by a jack.
3. Locating and Accessing the Rocker Arms
Accessing the rocker arms on a Small Block Chevy engine varies depending on the year and specific model. Consult your owner’s manual for specific instructions.
Accessing the Rocker Arms:
- Remove valve covers: Carefully remove the valve covers to expose the rocker arms and pushrods.
- Identify valve train components: Familiarize yourself with the location of intake and exhaust valves, rocker arms, and pushrods. Understanding your engine’s layout is key to successful valve adjustment.
4. The 5 Steps to Small Block Chevy Valve Adjustment
The process typically involves these steps:
- Locate Top Dead Center (TDC): Use the crankshaft pulley and timing marks to find TDC on the compression stroke for the cylinder you’re working on. This ensures the valves are in the correct position for adjustment.
- Loosen the rocker arm adjusting nut: Carefully loosen the lock nut on the rocker arm.
- Set the valve lash: Insert the correct feeler gauge between the rocker arm and valve stem. Adjust the pushrod length until you achieve the correct lash specified in your owner’s manual. This is where precise measurements are crucial for proper Small Block Chevy valve adjustment.
- Tighten the lock nut: Once the correct lash is achieved, tighten the lock nut securely to the manufacturer’s specifications. Avoid over-tightening, which can damage the components.
- Repeat for all valves: Rotate the crankshaft to the next cylinder and repeat steps 1-4 until all intake and exhaust valves are adjusted.
5. Double-Checking Your Work
After completing the adjustments, it’s crucial to double-check your work. Incorrect adjustments can lead to engine damage.
Verifying Valve Lash:
- Re-check the valve lash on each valve using the feeler gauge.
- Ensure all lock nuts are securely tightened.
- Consult your owner’s manual for torque specifications.
6. Reassembly and Final Checks
Once all valves are adjusted, reassemble the engine components.
Reassembly Procedure:
- Replace the valve covers, ensuring a proper seal.
- Reconnect the negative battery terminal.
- Start the engine and listen for any unusual noises. Unusual sounds often indicate an incorrectly adjusted valve.
7. Troubleshooting Common Issues in Small Block Chevy Valve Adjustment
Even experienced mechanics encounter problems during valve adjustments. Here are some common issues and solutions:
Common Problems:
- Incorrect lash: Double-check your measurements and ensure you’re using the correct feeler gauge. Improper Small Block Chevy valve adjustment can lead to engine damage.
- Bent pushrods: Bent pushrods can lead to incorrect lash. Inspect pushrods for any bends or damage.
- Worn rocker arms: Worn rocker arms affect the valve clearance. If excessive wear is observed, replacement may be necessary.
