Unfortunately, even the highest quality parts break 🤷♂️
This 25,000 mile C6 Z06, fitted with our 660 HP package that we installed in 2013, came in for a general health and maintenance check, along with an updated calibration file, MSD Atomic AirForce intake, and a Nick Williams throttle body. This car is also receiving upgraded 660 SP fuel injectors from Fuel Injector Clinic.
Due to its age and mileage, we recommended replacing the entire valve train. Upon disassembly, we discovered a cracked valve spring. OUCH!
This is why routine maintenance checks are KEY when owning a high performance vehicle . Luckily for this customer, we discovered this before any damage could be done.
