Once the product has been installed, it is your responsibility to “break in” the product properly. After the break-in period and 600-mile checkup, you must maintain the product to the original manufacturer’s specifications.
It’s important during this period to use a non-synthetic or non-synthetic blend oil in the OE specified weight for the duration of the break-in of your remanufactured engine.
Initial Startup
When applicable, valves must be readjusted to your vehicle’s manufacturer’s specifications. Refer to the factory shop manual or contact Customer Service for the proper procedure for your engine type.
