Camshaft Pitting
Critical Severity$40,000-60,000Symptoms
- Rough or uneven idle
- Valve train noise (ticking or tapping)
- Check engine light with misfire codes
- Reduced power or hesitation
- Metal debris in oil
Causes
- Metallurgical defects in original camshafts
- Insufficient lubrication during cold starts
- Extended storage without running
- Aggressive driving before oil is warm
Solution
Full camshaft replacement with improved aftermarket or OEM+ components. Engine-out service required. Our camshaft replacement includes lifetime warranty against pitting.
Prevention
Warm-up properly before spirited driving, annual oil analysis, regular inspection at major service intervals.
Clutch Wear
High Severity$30,000-50,000Symptoms
- Clutch slip under load
- Higher engagement point
- Difficulty finding neutral
- Grinding during shifts
- Burning smell during hard driving
Causes
- Normal wear from use
- Aggressive launches or track use
- Riding the clutch in traffic
- Improper driving technique
Solution
Complete clutch assembly replacement. Engine-out service required. Factory clutch or upgraded options available for improved pedal feel and durability.
Prevention
Proper clutch technique, avoid slipping at launch, don't ride the pedal in traffic, check wear percentage via PIWIS annually.
Cooling System Failures

How do I know if my CGT needs camshaft replacement?
Symptoms include rough idle, valve train noise (ticking or tapping), and misfire codes. Definitive diagnosis requires valve cover removal and visual inspection of camshaft lobes.
Is the Carrera GT reliable?
With proper maintenance from specialists, Carrera GTs are remarkably reliable for exotic supercars. Most issues stem from age, improper storage, or deferred maintenance rather than design flaws.
