How to Test for Blown Head Gasket
To test for a blown head gasket, perform a compression test or a cooling system pressure test. These tests will help diagnose the issue with your vehicle’s head gasket.
A blown head gasket can lead to serious engine problems if not addressed promptly. Symptoms such as overheating, white smoke from the exhaust, or coolant mixing with engine oil could indicate a blown head gasket. By conducting these tests, you can confirm the issue and take the necessary steps to repair it.
It’s crucial to address a blown head gasket promptly to prevent further damage to your engine and ensure the longevity of your vehicle.

Visual Inspection
When it comes to diagnosing a blown head gasket, a visual inspection is a crucial step in the process. By examining three key systems – the coolant system, oil system, and exhaust system – you can identify telltale signs of a potential head gasket issue.
Coolant System
Inspect the coolant system for any signs of a blown head gasket. Look for leaks, especially around the engine block and exhaust manifold. Check the coolant reservoir for signs of oil contamination or a milky appearance, which could indicate a head gasket problem.
Oil System
Examine the oil system for potential head gasket issues. Observe the engine oil for signs of coolant contamination. Look for a milky or foamy appearance on the dipstick or under the oil cap, as this could indicate a compromised head gasket.
Exhaust System
Check the exhaust system for indications of a blown head gasket. Look for excessive white smoke coming from the tailpipe during engine startup or acceleration. Additionally, a sweet smell in the exhaust fumes can be a sign of coolant entering the combustion chamber, pointing to a potential head gasket issue.
