My engine is making a ticking noise on cold start. Should I be worried?
For your 911 GT3 with a flat-six engine, a brief ticking on cold start is often normal — it's typically hydraulic valve lifters pressurizing.

However, if it persists beyond 30 seconds or gets louder, it could indicate:
1. Low oil level — check dipstick
2. IMS bearing wear (less likely on GT3)
3. Exhaust manifold leak
