A Ferrari 250GTE suffered a catastrophic engine failure when its crankshaft snapped on the motorway. Join Emblem's specialists as they tackle this unprecedented Ferrari engine rebuild against the clock.
A Motorway Nightmare: The Snap Heard Across the Motorway
Imagine the sound: a loud, metallic bang from the heart of your priceless Ferrari 250GTE while cruising on the motorway. This was the reality for one owner, who experienced every classic car enthusiast's worst nightmare: a catastrophic engine failure.
The diagnosis? Something even our lead technician, Tim, with his decades of Ferrari engine rebuild experience, had rarely, if ever, seen: a completely snapped crankshaft.
An Unprecedented Challenge for Ferrari Specialists
The 250GTE's Colombo V12 engine is a piece of automotive art, and a failure of this magnitude is exceptionally rare.
The Root Cause: A snapped crank is often the final result of a hidden flaw—perhaps a hairline crack from metal fatigue, a previous overspeed incident, or an oiling issue that led to catastrophic bearing failure. The investigation began to determine the exact trigger.
The Domino Effect: When a component as fundamental as the crankshaft fails, the damage is never isolated. The team had to meticulously inspect for collateral damage to:
Connecting rods and pistons
The engine block and main bearing caps
The cylinder heads and valvetrain
The 7-Month Masterpiece: A Ground-Up Engine Rebuild
With the owner's dream Italy/France road trip looming, the pressure was on. This wasn't just a repair; it was a total engine resurrection.
Full Teardown & Forensic Analysis: Every component was cataloged and inspected to understand the full scope of the failure.
Sourcing Rare Parts: Finding a correct, serviceable crankshaft for a Ferrari 250GTE is a challenge in itself, requiring a global network of classic Ferrari specialists.
Precision Machining & Balancing: The new rotating assembly was balanced to exacting tolerances to ensure flawless, vibration-free operation.
Meticulous Reassembly: Every bearing, seal, and gasket was carefully fitted by hand, following factory procedures refined by decades of hands-on experience.
Professional Dyno Testing: The final and most critical phase. Before the engine could be reinstalled, it had to be run on a dynamometer to break it in, check for leaks, verify oil pressure, and ensure it produced the power and torque expected from a healthy Colombo V12.
A Race Against Time for a European Adventure
The entire project—from receiving the broken engine to the final dyno sign-off—spanned 6-7 months of meticulous work. The stakes were high: a successful rebuild meant the owner's grand tour through the Alps and along the Riviera could go ahead as planned. A delay or issue meant disappointment.
The final moments on the dyno were tense. After hundreds of hours of work, the team’s expertise was put to the ultimate test. Would the engine run as smoothly and powerfully as it did decades ago?
