Known issues and risks

Listed from most frequently reported, each with its source.

PCV system / vapor recirculation fault

Often reported

The crankcase ventilation system (PCV/SFI valve) can clog or fail, causing excessive pressure or vacuum in the circuit, leading to oil consumption, leaks, or rough running.

Engine Bay

Timing Chain Tensioner Wear or Failure

Often reported

Metallic noises and misfires when cold are reported, caused by wear or failure of the timing chain tensioner. If the tensioner fails, the chain can slip, risking serious engine damage (piston/valve collision).
