1. Overheating: A blown head gasket can lead to loss of coolant, which can cause the engine to overheat. Keep an eye on the temperature gauge and look for any signs of overheating, such as boiling or bubbling coolant, steam coming from the engine, or a burning smell.
2. Coolant Leak: A blown head gasket can also cause coolant to leak from the engine. Check for any leaks around the head gasket area or coolant hoses.
3. Oil Leak: A blown head gasket can also cause oil to leak from the engine. Check the oil level and look for any signs of oil leaks around the head gasket area.
4. White Smoke: A blown head gasket can lead to combustion gases entering the coolant system, which can create white smoke coming from the exhaust. This smoke may have a sweet or acrid smell.
5. Rough Engine Idle: A blown head gasket can affect the engine's combustion and cause rough or uneven idling.
6. Compression Loss: A blown head gasket can lead to loss of compression in the engine, which can result in reduced power and performance.
If you suspect a blown head gasket, it's important to have the engine inspected by a qualified technician as soon as possible.
