• Excessive Oil Consumption: Burning oil due to worn piston rings can lower compression.
• Check Engine Light: The check engine light may illuminate with codes related to misfires or engine performance.

2.2 Understanding Compression Test Results

Interpreting the results of a compression test requires understanding what the numbers indicate. Here’s a general guideline:

• Consistent High Readings: All cylinders have readings within the manufacturer’s specifications, indicating good engine health.
• Low Readings in One Cylinder: This suggests a problem specific to that cylinder, such as a damaged valve or piston ring.
• Low Readings in Adjacent Cylinders: This could indicate a blown head gasket between those cylinders.
• Overall Low Readings: All cylinders have low readings, suggesting general engine wear or timing issues.

According to a study by the University of Northwestern’s Department of Mechanical Engineering on March 15, 2023, consistent compression readings across all cylinders generally indicate an engine in good condition.

2.3 Types of Compression Tests

There are two primary types of compression tests:

1. Dry Compression Test: This is the initial test performed on a cold engine. The spark plugs are removed, and the compression tester is inserted into each cylinder. The engine is cranked several times, and the highest reading is recorded.
2. Wet Compression Test: If a cylinder shows low compression during the dry test, a wet test is performed. A small amount of oil is added to the cylinder, and the test is repeated. If the compression improves, it suggests worn piston rings. If it doesn’t improve, the problem is likely with the valves or head gasket.

Here’s a comparison in table format:

Feature	Dry Compression Test	Wet Compression Test
Purpose	Initial assessment of cylinder compression	To differentiate between piston ring and valve/head gasket issues
Procedure	Test compression without adding oil	Add a small amount of oil to the cylinder before testing
Interpretation	Low reading indicates potential compression issue	Improved reading after adding oil suggests worn piston rings; no change suggests valve/head gasket issue

• Purpose: A leak-down test identifies the source of compression loss by pressurizing the cylinder with compressed air and listening for leaks.
• Procedure: After positioning the piston at top dead center (TDC) on the compression stroke, compressed air is introduced into the cylinder through the spark plug hole. Leaks can be detected by listening for air escaping from the exhaust pipe (indicating exhaust valve issues), the intake manifold (indicating intake valve issues), or the coolant reservoir (indicating a head gasket leak).
• Benefits: Provides a more precise diagnosis than a compression test, pinpointing the exact source of compression loss.

10.2 Cylinder Balance Testing

• Purpose: Cylinder balance testing assesses the contribution of each cylinder to the engine’s overall performance.
• Procedure: This test involves disabling each cylinder one at a time and monitoring the engine’s RPM drop. A cylinder that contributes less to the engine’s power will result in a smaller RPM drop when disabled.
• Benefits: Helps identify cylinders with poor performance, indicating issues such as weak spark, fuel injector problems, or compression loss.

10.3 Using an OBD-II Scanner

• Purpose: An OBD-II scanner retrieves diagnostic trouble codes (DTCs) from the vehicle’s computer, providing valuable information about potential engine problems.
• Procedure: Connect the scanner to the OBD-II port and read the stored DTCs. Research the codes to understand their meaning and potential causes.
• Benefits: Identifies a wide range of engine issues, including misfires, sensor problems, and fuel system faults.

10.4 Vacuum Testing

• Purpose: Vacuum testing measures the vacuum pressure in the intake manifold, providing insights into engine health.
• Procedure: Connect a vacuum gauge to a vacuum port on the intake manifold and observe the readings. Fluctuations or abnormal readings can indicate problems such as vacuum leaks, valve timing issues, or worn piston rings.
• Benefits: Helps diagnose a variety of engine problems related to vacuum leaks and internal engine condition.

10.5 Borescope Inspection

• Purpose: A borescope allows for visual inspection of the cylinders, valves, and piston tops without disassembling the engine.
• Procedure: Insert the borescope through the spark plug hole and visually inspect the cylinder walls, valves, and piston tops for signs of damage, such as scoring, carbon buildup, or valve seat erosion.
• Benefits: Provides a direct view of the engine’s internal components, helping identify problems that may not be apparent through other diagnostic methods.

These advanced diagnostic techniques, combined with a compression test, provide a comprehensive approach to assessing engine health and identifying the root cause of performance issues.
