•Pressure-test the entire cooling system and inspect every coolant hose by hand, brittleness or weeping at clamps is a deal-breaker without price reduction
•Check idle behaviour cold and fully warm, idle must settle to around 800 rpm; anything above 1,200 rpm warm indicates vacuum leaks or sensor faults requiring investigation
•Use a smoke machine or carb cleaner to check for vacuum leaks in aged hard plastic vacuum and evap lines throughout the intake system
•Verify the engine code and look for signs of a previous block swap, confirm correct Mk3-compatible block is fitted and engine mounts are secure with no excessive movement
•Scan the ECU for stored and pending fault codes before purchase, paying attention to coolant temp, idle, and ignition-related codes
•Inspect the wiring loom around the engine bay and behind the instrument cluster for amateur repairs, chafed insulation, or non-standard connectors
