The Shakedown Period

---

Congratulations on your newly modified vehicle! While every effort has been made to ensure a seamless conversion, modified vehicles behave differently than factory-standard cars. The first 800 to 1,500 kilometers are critical for identifying "teething issues"—small adjustments needed as new components settle and heat-cycle together for the first time.  What to Expect  In a custom build, parts from different eras or manufacturers are often working together in ways they weren't originally designed to. You may encounter:  Fluid Seepage: New gaskets, seals, and custom hose fittings may require a "re-torque" after they have reached operating temperature a few times. Small drips are common and often just require a minor tightening of a clamp or fitting.  Vibration & Harmonics: High-performance mounts or altered drivetrain angles can create new NVH (Noise, Vibration, Harshness) profiles. Some are normal characteristics of performance parts; others may indicate a need for alignment shims.  Sensor Calibration: Modern engines in older chassis rely on specialized electronics. You might see an occasional Check Engine Light (CEL) for non-critical items as the ECU "learns" its new environment and fuel maps.  Fastener Settlement: Suspension components and engine mounts can settle under load. It is vital to check the torque on major bolts (especially engine mounts and driveshaft bolts) after the first 150 kilometers.  Best Practices for New Owners  To ensure the longevity of your build, we recommend the following "Break-in" protocol:  The Visual Inspection: For the first month, pop the hood after every drive. Look for signs of rubbing (hoses against pulleys) or heat damage (wires too close to the exhaust).  Monitor Your Gauges: Don’t just look at them; learn what is "normal" for your specific build. Custom cooling systems often cycle differently than OEM ones.  The "Smell Test": Modern conversions shouldn't smell like raw fuel or burning oil. If you smell something acrid, pull over and investigate.  Short-Interval Oil Change: We recommend changing the oil and filter after the first 800 kilometers to flush out any assembly lubes or microscopic debris from the build process.  When to Call Us  If you experience a significant loss of power, a sudden change in oil pressure, or a persistent "mechanical" knocking sound, stop driving immediately. Small leaks can be addressed at your first scheduled inspection, but internal engine noises should never be ignored.  Note: A modified car is a living project. Staying proactive during these first few weeks ensures a reliable, high-performance machine for years to come.
