Updated to Address Known Factory Issues
One of the most important advantages of this engine is that it has been updated to address known factory concerns associated with the original platform.
The remanufacturing process incorporates improvements designed to:
- Enhance long-term durability
- Improve reliability
- Reduce wear-related concerns
- Support proper lubrication
- Extend engine service life
These updates help provide confidence for owners planning to keep their Wrangler for years to come.
Verified Oil Pressure Testing
Unlike many replacement engines that are simply assembled and shipped, this engine undergoes oil pressure verification with the oil pump installed.
This additional testing helps confirm:
- Proper oil pump operation
- Correct oil pressure levels
- Lubrication system performance
- Internal engine integrity
This added level of testing provides additional assurance that the engine is ready for installation and operation.
The Remanufacturing Process
Every engine undergoes a comprehensive remanufacturing process designed to restore performance, reliability, and durability.
Complete Cleaning and Preparation
The process begins with complete engine disassembly.
Cast iron components are hot tank cleaned while aluminum components are thermally cleaned to remove contaminants, carbon buildup, and accumulated residue.
This creates a clean foundation for rebuilding.
Advanced Inspection Procedures
Every major component undergoes extensive inspection before assembly.
Magnaflux testing is used to identify microscopic cracks, hidden structural flaws, and imperfections that may affect long-term reliability.
Visual inspections are also performed throughout the rebuilding process.
Precision Machining and New Components
Critical engine surfaces are CNC machined to restore factory tolerances and sealing surfaces.
New components installed during assembly include:
- New pistons
- New piston rings
- New bearings
- New lifters
- New oil pump
- New gaskets
- New Viton™ valve seals
- New freeze plugs
- New galley plugs
- New timing components where applicable
- New timing-driven water pump where required
These upgrades help restore factory performance while supporting long-term durability.
SIM Testing and Final Validation
Following assembly, every engine undergoes extensive SIM testing.
Testing procedures include:
- Oil system pressurization
- Cooling system pressurization
- Compression verification
- Internal sealing inspection
- Build quality validation
The crankshaft is rotated at high RPM under simulated operating conditions to verify engine integrity before shipment.
