•Perform a cooling system pressure test and use a combustion leak tester to rule out head gasket failure before purchase
•Remove the oil filler cap and inspect for milky emulsified oil, which indicates coolant intrusion via head gasket
•Inspect the PCV valve and intake manifold for heavy oil deposits indicating a long-neglected PCV system
•Start the engine cold and watch for white or blue exhaust smoke during warm-up, indicating head gasket or valve seal issues
•Check the valve cover perimeter and spark plug wells for oil seepage from a deteriorated valve cover gasket
•Test for low-RPM hesitation and chugging under light throttle, and investigate EGR and injector condition if present
•Ask whether the vehicle is a US-market Tacoma/4Runner (higher compression, 150 hp tune) or an export-market Hilux/Prado (lower compression, sub-120 hp tune), since parts and tuning specifics differ slightly

The power gap between the US and export tunes comes down to compression ratio and ECU calibration for local fuel octane, not a reliability difference. Both variants share the same block, head, timing components, and known failure points including the head gasket. Buy based on regional availability, service history, and condition rather than chasing the higher-power US spec.
