D&J Precision Machine Engine Limited Warranty 

Engine Warranty Coverage

Our engine limited warranty covers defects in workmanship under normal use for a period of 2 years or 100,000 miles, whichever comes first, from the date of purchase. The Street Performance Series Engines, Performance Series Engines, Predator Engines, and Enforcer 6.7 Cummins Engines have a 90-day warranty coverage period.

Registration

Register your engine within 30 days of purchase.  Failure to do so will void your warranty.  

Terms and Conditions

This engine warranty is valid only if:
- The engine is installed by a D&J Precision Machine approved technician.
- Regular maintenance is performed according to our schedule.
- Exclusions apply for misuse, unauthorized modifications, lack of proper maintenance, abuse, neglect, overloading, overheating, fuel system failures, or tuning. D&J Precision Machine can only cover workmanship-style errors.
- Proper break-in procedures must be followed as outlined in our break-in procedure documentation.
- If an engine is misdiagnosed by the shop, D&J Precision Machine will not be responsible for any costs associated with the misdiagnosis. The customer and/or shop will be responsible for D&J Precision Machine's time, materials, and shipping if misdiagnosed.

Engines Covered by the Warranty

Additional Exclusions for Essential Reman Engines:

• We cannot cover oil leaks except for the timing gear housing to block.
• Since there are many factors out of our control that need to be completed by the end user or the shop doing the install, we cannot cover any failures related to oil contamination or failures due to lack of oil pressure on start-up.
