Core Charges

The Core Charges are refunded as soon as we determine that your heads are useable for remanufacture.

Factors which eliminate heads for core use include:

  • heads that were machined too thin
  • prior and severe cracks which are not repairable.

Many smaller cracks in the seats are eliminated by replacing the seats and are usually fine.

We can also repair some cracks in the deck surface using Lock N Stitch® pins, but are unable to repair cracks which extend into injector holes, glow plug holes, or deep into a port.

Your core must be returned within 45 days of receiving your heads.

We DO NOT accept Chinese castings for cores.
