When you visit a mechanic, the diagnosis is often a “blown head gasket,” but the reality is frequently worse: the cylinder head itself is warped or cracked. A simple gasket change won’t fix a warped metal surface. The alternative is to send your old head to a machine shop. But it is expensive, takes weeks, and relies on successful welding to fix corrosion or cracks. Buying a whole new engine is overkill when your pistons and block are fine. You need a middle-ground solution that is faster and cheaper.
