What to Expect

Sophisticated DOHC head (uses torsion bar valve springs and eccentrically mounted rockers) can tangle valves if the engine’s used way into the red, but generally tough, only fails when the small-ends go. Look for slick gearbox, smooth mill above 7k, lack of oil leaks around clutch pushrod and no fumes from engine breather.
