WHY ENGINES & CYLINDER HEADS FAIL AND HOW BD SOLVES IT

A catastrophic engine failure often requires a complete long block replacement. Our BD Engine program offers several tiers, from remanufactured Precision Plus stock replacements to robust Heavy Hauler and Street Performance builds. These engines arrive pre-assembled from the oil pan to the valve cover, saving significant time on installation and ensuring all critical clearances and tolerances are met in a clean-room environment.

  • Blown Head Gasket

    Symptoms include coolant loss, white exhaust smoke, and milky oil.

    The BD Difference

    High cylinder pressures, often from performance tuning, can compromise the stock gasket.

  • Dropped Valve Seat

    A catastrophic failure where the valve seat dislodges, causing severe damage to the piston, cylinder walls, and head.

    The BD Difference

    This often necessitates a complete long block replacement.

  • Cracked Cylinder Head

    Can be caused by overheating or casting flaws.

    The BD Difference

    Look for external coolant or oil leaks, or internal leaks causing rough running and smoke.

  • Connecting Rod or Piston Failure

    Results in loud knocking noises or a 'windowed' block.

    The BD Difference

    Often caused by over-speeding or excessive cylinder pressure, requiring a new long block.

What is the difference between a long block and a short block?

A long block is a more complete engine, typically assembled from the oil pan to the cylinder head/valve cover. A short block is just the engine block with the rotating assembly (crank, rods, pistons) installed.

What is a core charge?

A core charge is a deposit refunded to you when you return your old, rebuildable engine or cylinder head. This allows us to remanufacture parts and keep costs down.

Should I get a fire-ringed cylinder head?

Fire rings are recommended for high-horsepower builds to provide a superior seal against very high cylinder pressures and prevent blown head gaskets. For stock or mildly modified trucks, it is not usually necessary.

Do BD long blocks come with fuel injectors or a turbo?

No, our long block assemblies do not include the fuel system, turbocharger, or other external accessories. You will need to transfer your existing components or purchase new ones.

Are these engines and heads legal in my state/province?

Emissions legality varies by part and application. Please check the individual product page for specific CARB EO status or emissions information before purchasing.

Do I need special tools to install a long block?

Engine replacement is a job for an experienced technician with the proper tools, including an engine hoist, specialty sockets, and torque wrenches. It is a complex job that requires a high level of mechanical skill.
