What are the symptoms of a blown head gasket?

[OLaura]

A blown head gasket can exhibit the following symptoms: 1. Insufficient engine power: If the head gasket is damaged between two cylinders, the engine will lack power, resulting in poor vehicle acceleration and performance. When removing the air filter, a 'popping' abnormal noise can be heard from the intake pipe during engine idle. 2. Blue smoke from the exhaust: If the damaged area of the head gasket connects to the oil passage, some engine oil may flow into the cylinder and burn, causing blue smoke to emit from the exhaust pipe. 3. Bubbles and boiling in the radiator: If the damaged area of the head gasket connects to the water jacket, bubbles and boiling may occur in the radiator, accompanied by white smoke from the exhaust pipe. 4. Abnormal noises from the head gasket: If the damaged area of the head gasket connects to the external atmosphere, the engine's performance and fuel efficiency will deteriorate, and a loud 'popping' noise can be heard from the damaged area.
