What is the purpose of a compression test?
—A compression test helps diagnose engine issues by measuring the pressure created during the compression stroke.
What are the types of compression tests?
—The types of compression tests include static, running, and snap tests.
How can compression test results help identify valve train problems?
—If compression test results are consistently low on a specific cylinder, it may indicate a valve train problem on that cylinder.
What is a leak down test?
—A leak down test is a follow-up test that identifies the location and severity of compression loss in an engine.
How does engine vacuum testing contribute to diagnostics?
—Engine vacuum testing helps assess the mechanical integrity of an engine and can identify issues such as piston ring leaks or valve problems.
