OBR Remanufacturing Process
OBR's remanufacturing process begins with a used engine core that is completely disassembled, cleaned, and inspected. Components are checked for condition and specifications, and parts that do not meet requirements are replaced during the remanufacturing process. OBR long blocks are assembled with the cylinder heads installed and timed on the short block and are built to meet OE specifications.
Core Return Refund
There is no additional core charge added to your purchase.
Core return paperwork will be included with applicable long blocks. If your original long block is returned and passes inspection as an acceptable rebuildable core, you may qualify for the refund amount associated with the long block you purchased:
- 1999-2000 / YA-P4F-15L-R: No core refund
- 2001-2004 / YA-P4F-16L-R: Up to $75 core refund
- 2005-2017 / YA-P4F-17L-R: Up to $225 core refund
