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.
You are responsible for core return shipping cost.

If you plan on returning your core you have two options.

Thoroughbred Diesel offers defer the upfront core charge when purchasing via credit card payment.

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 Ra 13 finish. The piston diameter measured to the nearest .0001? matched to cylinder bores. The Cylinder block is surfaced to a finish of 30 Ra 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 Dodge Cummins 5.9L Engine (and how we fix them)

Cylinder Heads- While there aren’t as many issues with the bottom end of the Cummins, there are really BIG problems in the head department.
-Valve seats fallout contacting the piston and cause catastrophic failure. We machine oversize valve seats within creased press fit area to remedy this issue.
-Stamped gallery plugs in the heads blow out causing a mixture of oil and coolant, destroying the bearings. We thread the head and insert threaded plugs to make sure this issue never rears its ugly head.
-Freeze plugs in the block blow out leaving you at best stranded on the side of the road, at worst, with a severely overheated engine in need of remanufacturing. Every new Choate Cummins engine comes standard with billet freeze plugs that are “blow out proof” using a tie bar bolting them into the side of the block.
