Renk is still manufacturing them, up to 1500HP, in their AVDS-1790 series.
The current M88A2 HERCULES 70 ton recovery vehicle is using the 1050HP version of the AVDS-1790, and from what little I have read it has a reputation for good reliability.
But the upcoming M88A3 80 ton recovery vehicle (currently being tested by the U.S. Army) will abandon the air cooled diesel for a liquid cooled 1350HP Caterpillar C32 engine.

RENK America Combat Propulsion Systems is the Original Equipment Manufacturer (OEM) of the AVDS-1790 Series Engine, currently used in platforms including the M60, the M88 Recovery Vehicle, and the M48.
For over 60 years, more than 35,000 AVDS-1790 engines have been engineered, manufactured, overhauled and upgraded in Muskegon, Michigan, ensuring the highest quality and reliability to our customers.
AVDS-1790 Series diesel engines are turbocharged, air cooled 12-cylinder, 90 degree Vee configurations. Power ratings range from 750 - 1500 HP. Air cooling for engine cylinders, as well as engine oil, transmission oil, and charge air coolers, are provided by direct drive fans mounted in the center of the Vee.
Extensive use of aluminum components throughout the engine provides a high power-to-weight ratio. The compact design of the AVDS-1790 engine includes individual and easily replaceable cylinders. Overhead valves are used with an overhead camshaft in the top of the engine to facilitate rapid service. Air cooling eliminates the maintenance burden of liquid cooling systems.
