BMW Head Gasket Repair in Culver City: Symptoms, Diagnosis, and What It Actually Costs
Head gaskets do not fail at random. They fail when an engine has been subjected to sustained thermal stress that exceeds the gasket’s design tolerance. The gasket seals the combustion chamber from the coolant passages in the cylinder head, and it does this reliably for hundreds of thousands of miles under normal operating temperatures. What it cannot do indefinitely is compensate for a cooling system that is running marginal.
