Nissan Pathfinder
4.0L V6 naturally aspirated. Robust and powerful, high fuel consumption.
V6 petrol breathes life into the big beast
272 hp V6 gives the Pathfinder unexpected thrust — no sports car, but no longer a slouch.
Engine Weaknesses 2
The timing chain guide rails of the VQ40DE wear at high mileage. Nissan used plastic slide rails on early models that become brittle. A broken chain can cause catastrophic engine damage.
Symptoms: Rattle on cold start, metallic clattering, engine warning light
The rear crankshaft seal of the VQ40DE becomes leaky at higher mileages. Oil loss between engine and gearbox is typical. Repair is labour-intensive as the engine or gearbox must be removed.
Symptoms: Oil patch under engine/gearbox, dropping oil level, oily smell after driving
