Are there any major issues after repairing a blown head gasket in a car?

[CoraLynn]

Blown head gasket refers to the damage of the cylinder head gasket. Check if the cylinder head is deformed; if normal, replace the cylinder head gasket. This situation has no impact at all. Below is additional information: 1. Causes: The engine working under heavy load for a long time, frequently experiencing detonation combustion, leading to local high temperature and pressure in the cylinder that erodes the head gasket. Excessively advanced ignition timing or injection timing, resulting in excessively high peak pressure and temperature in the cycle. 2. Symptoms: Bubbles appearing in the radiator, boiling over, and white smoke from the exhaust. The engine's power is poor, fuel economy deteriorates, and there is a sharp popping sound from the damaged gasket. Some engine oil may enter the cylinder and burn off, causing blue smoke from the exhaust.
