Blown head gasket

A blown head gasket is a severe engine problem that can lead to overheating, loss of power, and costly repairs. Symptoms include white smoke from the exhaust, indicating coolant entering the combustion chamber, overheating due to coolant loss, and milky or frothy oil on the dipstick, which suggests coolant mixing with oil. Drivers may also notice bubbling in the radiator, a persistent sweet smell from coolant leaks, and poor engine performance. In some cases, the vehicle may struggle to start, and the check engine light may illuminate due to misfiring or compression loss. A blown head gasket can be caused by prolonged engine overheating, manufacturing defects, or excessive engine pressure from turbocharged applications. Ignoring a blown head gasket can lead to severe engine damage, including warped cylinder heads or a complete engine failure. Immediate action is required to prevent further damage, and in many cases, the repair process involves removing and resurfacing the cylinder head before installing a new gasket. Regular coolant checks, maintaining proper engine temperature, and addressing overheating issues early can help prevent head gasket failure.
