Tools & Supplies You'll Need:
* Repair manual: Absolutely essential for torque specs, diagrams, and specific procedures.
* Engine hoist or stand: The engine will likely need to be partially supported or removed for easier access.
* Socket set and wrenches: Various sizes for bolts, nuts, and other fasteners.
* Torque wrench: Crucial for accurate tightening of bolts and preventing damage.
* Valve spring compressor: Necessary for compressing the valve springs to remove and install lifters.
* Lifter removal tool: Helps remove the lifters without damaging them.
* New lifters: Purchase high-quality replacement lifters.
* New valve cover gasket: Replace this while you have the valve cover off. Consider also replacing the rocker arm gaskets.
* Clean rags: For keeping everything clean.
* Drain pan: For draining oil.
* Jack stands: If lifting the vehicle.
* Safety glasses and gloves: Essential for protecting yourself.
General Steps (Highly Simplified):
1. Disconnect the battery: Always disconnect the negative terminal first.
2. Drain the engine oil: Completely drain the oil before starting.
3. Remove the valve cover: Remove the valve cover bolts and carefully lift off the valve cover.
4. Remove rocker arms: Remove the rocker arm shafts and rocker arms. Keep them organized to ensure correct reinstallation.
5. Compress the valve springs: Using the valve spring compressor, compress the springs on each valve to remove the keepers. Then carefully remove the valves. This step requires precision and patience.
6. Remove lifters: Use a lifter removal tool to carefully extract the worn lifters.
7. Install new lifters: Install the new lifters, ensuring they are seated correctly.
8. Reassemble: Carefully reassemble everything in reverse order, paying close attention to the sequence of steps. Use the repair manual as your guide. This includes reinstalling the valves, springs, keepers, rocker arms, and valve cover.
9. Reinstall valve cover and other components: Don't forget the new valve cover gasket. Tighten all bolts to the specified torque.
10. Fill with oil: Add the correct amount of oil.
11. Start the engine: After ensuring everything is properly reassembled, start the engine and check for leaks and unusual noises.
Important Considerations:
* Timing chain: Be very careful not to disturb the timing chain during this process. Incorrect timing can severely damage the engine.
* Oil pressure: Low oil pressure can damage the lifters. Ensure your oil pump is working correctly before running the engine after the repair.
* Professional help: If you're not comfortable with this type of repair, take your vehicle to a qualified mechanic. The cost of engine repair far outweighs the cost of professional labor.
This process is a significant undertaking. The specifics and complexity vary slightly depending on the exact configuration of your engine. Again, use a repair manual specific to your 1995 S10 2.2L engine. This will provide detailed illustrations, torque specifications, and crucial steps to avoid damage. Failing to do so may result in engine damage.
