Can anyone tell me why Nissan used a timing belt instead of a chain for our Pathy engines (the VG30 and 33s)?
Chains are more durable and much less likely to snap and cause a piston to eat a valve.
Belts must be replaced every 60,000 miles (an expense I'd rather not pay).
Since the VGs (in the trucks anyway) don't need to rev that high, the chain seems much more practical. At least Nissan's reliability and durability somewhat offsets the fact that they can be a PITA to work on.
