Mechanic Rates: Independent shops and dealerships have different hourly labor rates. Dealerships usually charge more.
Diagnostic Add-ons: The compression test is often part of a larger diagnostic process. If the mechanic discovers other issues, like faulty spark plugs or damaged wires during the test, those might be added to the bill.

The Diagnostic and Repair Process: Unveiling Engine Secrets

An engine compression test isn’t just about getting a number; it’s about understanding the health of your engine’s cylinders. Here’s how it works:

How are Engine Compression Tests Diagnosed?

The test identifies cylinders with low or insufficient compression. Low compression can stem from issues like:

Damaged piston rings, pistons, or cylinder walls
Bent, worn, or stuck intake and exhaust valves
A deteriorated head gasket
Exhaust problems like a clogged catalytic converter or muffler.

How are Engine Compression Tests Done?

The technician ensures the engine oil level is normal and warms up the engine.
The ignition and fuel systems are disabled to prevent starting.
The spark plug wires are disconnected, and the spark plugs are removed.
A compression tester is installed in each spark plug hole, one at a time.
The engine is cranked over briefly, and the gauge on the tester reveals the pressure.
The readings are recorded for each cylinder.
The technician compares these readings to the manufacturer’s specifications. Significant variations indicate a problem.
