Cylinder Leakdown Testing in Saint-Léonard, QC
Professional Cylinder Leakdown Testing Services
At Garage MLR, we specialize in cylinder leakdown testing in Saint-Léonard, QC, helping drivers diagnose internal engine issues with precision. A leakdown test is one of the most effective methods to evaluate an engine’s condition, allowing us to detect air leaks that may lead to power loss, misfires, or excessive oil consumption. By performing this test, we can identify worn piston rings, valve seat leaks, or head gasket failures before they escalate into costly repairs.
The Importance of Cylinder Leakdown Testing
A properly functioning engine requires tight cylinder sealing to ensure efficient combustion. Even minor leaks can reduce power output, increase fuel consumption, and lead to long-term engine wear. A leakdown test provides a deeper insight into potential failures, allowing vehicle owners to address small issues before they develop into major mechanical failures.
If your vehicle experiences any of the following symptoms,
it may be time for a cylinder leakdown test:
- Rough idling or engine misfires
- Reduced acceleration or power loss
- White smoke from the exhaust
- Difficulty starting the engine
- Increased oil consumption
How Cylinder Leakdown Testing Works
During the test, our technicians introduce a controlled amount of air pressure into each cylinder while the piston is in a closed position. By monitoring how much air escapes and where it exits, we can determine the specific cause of compression loss.
Common leak sources and what they indicate:
- Intake manifold leak: Valve issues
- Exhaust manifold leak: Exhaust valve wear
- Coolant bubbles: Head gasket failure
- Crankcase air leak: Worn piston rings
