- Visual Inspections: We examine the engine block, oil pan, and cylinder head for cracks or stress marks.
- Internal Component Checks: We verify the integrity of the camshaft, crankshaft, and valvetrain assembly.
- Pressure Performance Testing: We run comprehensive hot oil pressure checks and individual cylinder leak-down tests to prove internal sealing.
