Cam chain tensioners 1990–2000
What to check: Ask whether the original tensioners were replaced with the later manually adjusted ones, and listen for a rattle off the throttle.
Goodwood says the early 5.7's hydraulic tensioners can in time let the chain snap, and that the later manual ones are often fitted instead. Seven owners in three FerrariChat threads raise the tensioners too.

What to check: In a high gear, accelerate from low revs and feel for slip, and make sure it shifts cleanly when warm. Ask when the clutch was last done.
Six owners in four FerrariChat threads call the clutch the main worry, and five say a clutch job means taking the engine out.

Sought after: Early rear-drive cars 1990–1993
