•Cold-start the engine from fully cold and listen for at least 5 seconds for metallic chain rattle before the oil pressure builds
•Ask specifically whether the tensioner oil check valve retrofit has been carried out
•Request full service history showing oil changes at or below 10,000 km with approved 5W-40 fully synthetic oil
•Ask about or arrange a borescope check of the intake valves for carbon buildup, or confirm a walnut blast has been done
•Run an OBD scan for fuel trim, misfire, and oil pressure fault codes before purchase
•Test cold-start behaviour after the car has sat overnight, checking for hesitation or backfiring that points to fuel pump wear
•Check oil level against the dipstick rather than relying on the dashboard gauge, and ask the seller about consumption between services

Timing chain tensioner and guide rails
Cold-start test for rattle, retrofit oil check valve if not already done, replace guide rails if worn
80,000-150,000 km
High-pressure fuel pump and cam follower
Check fuel pressure trims and fuel filter for metal debris, replace pump if misfires or cold-start backfiring present
100,000-160,000 km
Intake valves
Borescope inspection and walnut blast if significant carbon deposits found
80,000-120,000 km
