Replacement crankcases and short blocks are not stamped with an engine number or engine model designation.
To make it possible to identify the engine installed in a vehicle, the workshop performing repairs has to stamp the engine model designation in the crankcase in the engine number block.
Example:
119.974 (engine model designation in model
124.036), see 01-0010 in this connection.
The "closed-deck" design of crankcases are fitted from the start of series production with HELI-COIL inserts for the cylinder head bolts.
Standard up to engine:
