Installation Guidelines

Proper installation of a camshaft and lifter kit is critical for engine performance and longevity. It is highly recommended that installation be performed by a qualified automotive technician. Always refer to your specific engine's service manual for detailed disassembly and reassembly procedures.

Key Installation Steps:

1. Engine Preparation:

   Carefully disassemble the engine's top end, including valve covers, rocker arms, pushrods, and cylinder heads (if necessary). Remove the timing cover, timing chain/gears, and the old camshaft. Ensure all old lifters are removed.

2. Component Inspection:

   Thoroughly clean and inspect all related engine components, including the lifter bores, cam bearings, and timing chain components. Replace any worn or damaged parts.

3. Camshaft and Lifter Lubrication:

   Apply the supplied Edelbrock assembly lubricant generously to all camshaft lobes and journals. Also, lubricate the bottom of each new hydraulic lifter with the assembly lube. This is crucial for preventing wear during initial engine startup.

4. Camshaft Installation:

   Carefully slide the new camshaft into the engine block, ensuring not to damage the cam bearings. Rotate the camshaft as needed to align it properly.

5. Lifter Installation:

   Install the new hydraulic lifters into their respective bores. Ensure they slide freely. It is critical that new lifters are always installed with a new camshaft to ensure proper break-in and prevent premature wear.

6. Timing Component Installation:

   Install the timing chain and gears, ensuring correct timing alignment according to your engine's service manual. Incorrect timing can lead to severe engine damage.

7. Reassembly and Adjustments:

   Reassemble the remaining engine components, including pushrods, rocker arms, and valve covers. Follow the manufacturer's torque specifications for all fasteners. For hydraulic lifters, follow the specific pre-load adjustment procedures outlined in your engine's service manual.

8. Engine Break-in:

   A proper break-in procedure is essential for the longevity of the camshaft and lifters. Start the engine and immediately bring the RPMs up to 2000-2500 RPM, varying the speed for the first 20-30 minutes. This ensures adequate oil splash lubrication to the camshaft lobes and lifter faces. Avoid prolonged idling during this period. After the initial break-in, change the engine oil and filter.

Important: Always use a high-quality engine oil with appropriate ZDDP (Zinc Dialkyldithiophosphate) content, especially during break-in, to protect flat-tappet camshafts and lifters. Consult your engine builder or oil manufacturer for recommendations.

Operating Characteristics

The Edelbrock 2167 Performer-Plus Camshaft and Lifter Kit is engineered to provide a significant improvement in engine performance. Users can expect:

• Optimized Torque and Horsepower: Designed to produce peak performance from off-idle up to 5,500 RPM, making it suitable for street performance applications.
• Improved Throttle Response: The camshaft profile enhances the engine's responsiveness to throttle input.
• Smooth Idle: While offering performance gains, this camshaft is designed to maintain a relatively smooth idle, characteristic of the Performer-Plus series.

These characteristics contribute to a more engaging driving experience without sacrificing streetability.

Maintenance

Beyond the initial break-in procedure, the primary maintenance for the camshaft and lifters involves adhering to a regular engine oil change schedule. Use high-quality engine oil that meets or exceeds your engine manufacturer's specifications. For flat-tappet camshafts, continued use of oils with adequate ZDDP levels is recommended to prevent premature wear.

• Regular Oil Changes: Follow your vehicle manufacturer's recommended oil change intervals.
• Oil Type: Ensure the engine oil used is compatible with flat-tappet camshafts, especially in older engine designs.
• Engine Monitoring: Pay attention to any unusual engine noises, especially from the valve train, which could indicate a potential issue.

Proper engine cooling and fuel system maintenance also contribute to the overall health and longevity of all internal engine components, including the camshaft and lifters.

Troubleshooting

If you experience issues after installing the Edelbrock 2167 Performer-Plus Camshaft and Lifter Kit, consider the following common areas. Professional diagnosis is always recommended for complex engine problems.

• Rough Idle or Poor Performance:

  Verify ignition timing and fuel mixture settings. Incorrect camshaft timing (e.g., timing chain installed incorrectly) can cause significant performance issues. Check for vacuum leaks.

• Valve Train Noise (Tapping/Clattering):

  Ensure hydraulic lifter pre-load is correctly set. Insufficient oil pressure or incorrect oil viscosity can also contribute to lifter noise. Inspect for bent pushrods or worn rocker arms.

• Engine Misfire:

  Check spark plugs, ignition wires, and coil packs. Verify fuel injector operation. Incorrect valve timing can also lead to misfires.

• Oil Pressure Issues:

  Ensure adequate oil supply and proper oil pump function. New cam bearings should be properly lubricated during installation. Low oil pressure can severely damage the camshaft and lifters.

Note: Many performance issues can stem from factors unrelated to the camshaft itself. A comprehensive diagnostic approach is essential.
