## ⚙️ Key Features

-   257 kg
-   Supersedes 23204946, previously catalogued as a crankcase
-   11 TAD series engine applications

## 🔌 Function

Forms the engine's main structure, carrying the cylinders, crankshaft bearings and all mounted assemblies.

## ⚠️ Common Signs of Failure

-   Cracking, often between a bore and a coolant passage
-   Main bearing bores worn, oval or misaligned
-   Liner seats corroded or eroded
-   Coolant leaking externally or into a bore
-   Deck face out of flat, causing repeat head gasket failure

## 🛠️ Service Notes

-   At 257 kg this is a crane lift and the largest single component in this range
-   A replacement block is a full engine rebuild in practice — cost it against an exchange engine before committing
-   Have the block crack-tested and the bores and deck measured before building it up
