Top 10 Questions for Engine Setter Interview

1. Describe the process of setting the valve timing on an overhead cam engine?

• Remove the valve cover and timing belt or chain.
• Align the crankshaft at top dead center (TDC) on the compression stroke.
• Install the camshaft(s) with the timing marks aligned with the crankshaft.
• Install the timing belt or chain and tension it according to specifications.
• Double-check the valve timing using a dial indicator or other method.

2. How would you troubleshoot an engine that is misfiring at high RPMs?

Check the ignition system

• Inspect the spark plugs and wires.
• Test the ignition coil and module.

Check the fuel system

• Inspect the fuel filter and fuel pump.
• Test the fuel pressure and flow.

Check the mechanical components

• Inspect the valve clearances.
• Check the timing belt or chain for wear or damage.

3. What are the key specifications that you must follow when setting the timing on a diesel engine?

• Injection timing
• Valve timing
• Turbocharger boost pressure
• Exhaust gas temperature
• Fuel pressure

4. How do you adjust the backlash in a gear train?

• Loosen the mounting bolts for the gear that is being adjusted.
• Insert a feeler gauge between the gears and adjust the backlash to the specified tolerance.
• Tighten the mounting bolts and re-check the backlash.

5. What is the difference between a hot and cold engine set?

• A hot engine set is performed when the engine is at operating temperature.
• A cold engine set is performed when the engine is cold.

6. What are the different types of engine timing tools?

• Timing lights
• Dial indicators
• Compression gauges
• Stroboscopes
• Scan tools

7. How do you use a timing light to set the ignition timing?

• Connect the timing light to the engine’s number one spark plug wire.
• Start the engine and point the timing light at the timing marks on the engine.
• Adjust the distributor or ignition module until the timing marks align with the specified timing.

8. What is the importance of using the correct torque specifications when tightening engine components?

• To ensure that the components are properly tightened and will not come loose.
• To prevent damage to the components or the engine itself.
• To ensure that the engine operates properly and efficiently.

9. What are the most common causes of engine timing problems?

• Worn or damaged timing belt or chain
• Slipped timing belt or chain
• Faulty timing sensor
• Faulty ignition system
• Faulty fuel system

10. What are the benefits of using a scan tool to diagnose engine timing problems?

• Scan tools can provide real-time data on engine timing and other engine parameters.
• Scan tools can help to identify the root cause of engine timing problems.
• Scan tools can be used to reset engine timing after repairs have been made.
