Minor Body and Structure

Fibreglass Nose Section Cracking

Symptoms

Hairline cracks in the fibreglass nose section, particularly around stress points (headlight surrounds, bonnet latch area, mounting flanges).

Cause

Fibreglass becomes brittle with age and UV exposure. Vibration from driving and thermal cycling create stress cracks. Poor previous repairs using incorrect resin or fibre can also cause cracking.

Fix

Professional fibreglass repair using the correct resin system and fibre layup.

Cosmetic cracks can be filled, but structural cracks require backing reinforcement.

A skilled fibreglass specialist can make invisible repairs.

Cost: $500-3,000 AUD depending on extent.

Cost mentioned in fix

Cost: $500-3,000

Other known issues

Common Body and Structure

Galvanic Corrosion at Mixed-Metal Joints

White powdery corrosion on aluminium panels, particularly where they attach to the steel chassis or steel substructure. Panels may become loose or develop cracks at attachment points.

Minor Body and Structure

Steel Chassis Corrosion

Surface rust progressing to pitting and eventually perforation of the steel backbone chassis, floor sections, and structural members.

Common Engine, 3M 2.0L DOHC Inline-6 (Yamaha-Built)

Carburettor Deterioration and Synchronisation Drift

Rough idle, uneven power delivery, flat spots during acceleration, poor fuel economy, and difficulty starting. The engine may run rich on some cylinders and lean on others.

Critical Engine, 3M 2.0L DOHC Inline-6 (Yamaha-Built)

Timing Chain Stretch

Rattling or slapping noise from the front of the engine, particularly on cold startup. In advanced cases, the cam timing shifts, reducing power and causing rough running.

Critical Engine, 3M 2.0L DOHC Inline-6 (Yamaha-Built)

Oil System Leaks (Dry Sump)

Oil puddles under the car, oil residue on the engine and chassis, dropping oil level in the external oil tank. Potential oil starvation if leaks are severe.

Common Engine, 3M 2.0L DOHC Inline-6 (Yamaha-Built)

Valve Clearance Drift

Ticking noise from the valve train at operating temperature, gradual loss of power, uneven cylinder performance.
