Subaru Diesel Forged Engine Block (EE20Z)

We specialize in the full reconditioning of EE20Z engine blocks affected by broken crankshaft bearing holders - a common design flaw across all generations of this engine (2008-2018).

The Problem:

The EE20Z engine suffers from an inherent weakness that leads to excessive vibrations at the crankshaft bearings. Over time, this results in bearing failure, causing the crankshaft to seize or even snap in half. This failure also bends the connecting rods, leading to escalating repair costs. Simply replacing the engine does not address the root cause, as all Subaru diesel engines of this generation are affected by the same design flaw.

Our Solution:

We fully remanufacture the engine block, machining and installing new, reinforced bearing supports from high-grade steel blocks using CNC machining and precision boring. This process allows for the installation of a standard-size (STD) crankshaft with STD bearings, ensuring durability and reliability beyond the factory design.

Most breakages are repairable, however, it is best to contact us before sending your engine.
