•Check oil dipstick level and note the difference between current mileage and last oil change; any drop over 4,000 km indicates active oil consumption
•Warm up the engine fully and inspect for blue smoke from the exhaust at idle and during rev blips
•Perform a full OBD-II scan including SRS/airbag module and check for any stored or pending fault codes
•Check the VIN against NHTSA's recall database for outstanding Takata airbag inflator work
•Ask for documented coolant service history and inspect coolant reservoir for any oily residue or milky contamination suggesting internal water pump seepage
•Test both front seat belt retractors and check dashboard surface for stickiness or grey discolouration that may cause windshield glare
•Listen for timing chain rattle on cold start; any metallic rattling before oil pressure builds is a red flag requiring immediate chain and guide inspection

Timing Chain & Guides
Inspect for stretch, noise, and guide wear; replace if any rattle on cold start is present

Engine Oil Level
Check at every fuel stop due to documented oil consumption; do not rely solely on service intervals

Takata Front Airbag Inflator
Certain 370Z (Z34) model years were included in the broader Takata airbag inflator recall campaigns affecting the Nissan lineup, where the inflator can rupture and send metal fragments into the cabin during deployment.

All 370Z power variants share the same block, timing chain, and internal water pump, so the known failure points (oil consumption, water pump) apply equally regardless of hp figure. The NISMO's extra oil cooler is a genuine benefit for track driving but does not remove the oil consumption risk. Choose based on documented oil consumption history and maintenance records rather than the advertised power output.
