01VG30DE/VG30DET Timing Belt Failure
The VG30 engine family uses a rubber timing belt rather than a chain. At the age and mileage of F31 Leopards now in circulation, the belt is frequently original or has an unknown service history. Belt failure causes complete valve-to-piston contact as the VG30 is an interference engine, resulting in catastrophic cylinder head damage. The belt tensioner and idler pulleys are also age-susceptible and must be replaced concurrently.
