  • Where do I find My Engine Serial Number?

    Depending on the manufacturer and application of your engine, The engine serial numbers or vehicle identification numbers may be in different locations. Please refer to our Identifying Your Engine page for specific directions in identifying your engine.

  • What Gaskets are Included in the Gasket Set?

    Gaskets sets are specific to the type of long block You are ordering and your application. Please see our What's In The Gasket Kit page for specifics as to your engine.

  • Do I Need to Get New Injectors for My Gas or Diesel Long Block?

    You are required to have your injectors rebuilt with new injector nozzles installed by a Bosch, Delphi, or OE fuel injection repair facility.  You can also replace your injectors with new or remanufactured stock injectors, preferably from the equipment manufacturer.  

  • Do I Need to Get a New Oil Cooler For My Gas or Diesel Long Block?

    Yes, you are required to install a new oil cooler with your new long block for the warranty to be valid.  We will happy to include an oil cooler with your diesel long block if you wish.  View our sales page or ask your salesperson for pricing. 

  • Are your upgraded pistons ceramic coated?

    The pistons that have a coating are covered with an industrial graphite, anti-wear, thermal barrier coating produced by DuPont.  This helps with the durability of your pistons.

  • I already have head studs, can I install them myself & will it affect my warranty?

    It is not recommended to re-use head studs in most all cases.  The heat cycles that the stud encounters can change the physical properties of the stud and alter the torque and clamping force applied to the head gasket.  We believe that its not worth the risk of an engine failure when used head studs are installed.

  • Does the 6.0L or 6.4L Powerstroke come standard with ARP head studs?

    The standard long block engine will come with the new head bolts, but we do offer long block engines that include head studs.  We also offer the 5.9L & 6.7L Cummins, all 6.6L Duramax, and the 7.3L, 6.4L, and 6.7L Powerstroke engines for sale with head studs as well.

  • Do you offer an upgraded piston on the 6.4L Powerstroke long block?

    We offer the HD Piston upgrade for the 6.4L Powerstroke.  This is a Mahle piston that is cast without the re-entrant bowl or the “lip” in the top of the dish.   This makes the piston much more durable and considerably less likely to break, crack, or melt. 

  • Are your Engines Dyno Tested?

    We do test the long block on industry leading testing equipment to insure equal compression, resistance, vacuum, and pressure on all cylinders, oil, and coolant systems.  We offer dyno testing on diesel complete drop-in engines. 

  • Is There a Core Charge Associated with Your Engines?

    There is normally no core charge billed at the time of placing the order for a diesel long block. This is providing you have a good core to return. Up front core charges will be applied if paying by ACH or check or if you know of damage to your existing core. Core charges will be billed when the core has not been returned within our advertised core return policy or if a damaged core is returned to us. Blackwater Engines has up to 90 days to complete the core inspection and complete billing. For more information please see our Core Policy page. 

    The core charge is billed at the time of purchase for the diesel complete running engine. The policy on the core return is that it must be assembled and in the original crate with all of the components included on the core. There is a no hassle policy on broken components.
