Terms & Conditions for Cores

Many stock replacement parts such as turbos, injectors, injection pumps, and high pressure oil pumps have a core charge that is associated with the new replacement part. You must return the old part to receive a refund on the core charge.

In some cases, the core is not reusable, such as in the event of a cracked case, at which point the core deposit would not be credited as the core component is not reusable.
Cores that have been disassembled and/or have missing and/or damaged major components will not receive full core credit.
Returned cores must be on a "like-for-like" basis, meaning that the returned core has the exact same fitment as the remanufactured component that was purchased. If the core is not "like-for-like," your core may not be eligible for return/credit.

Full CNC blue print machining, (bore, deck, hone and line honed) – The Cylinder bores are blue print bored to a true 90 degrees from the crankshaft center line, prior to being diamond honed to within .0002? for precise piston to cylinder bore clearances. We main bore and line hone the crankshaft which is honed to precisely align the crankshaft in the engine block. We bore the block back to the crankshaft center line and hone the block to RA13 finish. The piston diameter measured to the nearest .0001? matched to cylinder bores. The Cylinder block is surfaced to a finish of RA30 or lower, which meets the factory specification in both flatness and smoothness for the block to head sealing surface. This is mandatory for proper sealing of a MLS Gasket.

Common Issues With The Ford Powerstroke 6.4L (and how we fix them)

Piston Cracking- The 6.4L was plagued with cracking issues due to the design of the combustion bowl. We use a different piston that was originally designed for the commercial
application of the engine.
Crankshaft Runout–Inherent crankshaft runout issues a recommend due to the low-speed-high-load design of the turbo systems (high boost at low RPM). This causes the crankshaft to runout of round, taking up the oil clearances for the mains and causing catastrophic failure. We DO NOT approve the bending of the crankshaft to straighten, (which is common practice with many engine rebuilders) as material has memory and will result in a relapse of the original condition. For this cause we machine the crankshaft to a truly round and concentric state from journal to journal. This allows the hydro-dynamic wedge created by the oil to do its job.
