Honda’s largest and most well-liked B-series engine is the B20B. An aluminum cylinder block with steel liners serves as the model for the representatives of this series. The engine features a sixteen-valve twin-shaft head. It makes use of a timing belt that needs to be changed on time to prevent breaking. Because the engine lacks hydraulic lifters, the valves must be adjusted on a regular basis. The VTEC variable valve timing system does not exist.
The first generation of the CR-V crossover is the main product of the 2.0-liter Honda B20B engine, which was manufactured from 1995 to 2002. The only difference between the two generations of the B20B motor is the level of forcing.
Internal combustion engines (B16A, B16B, B18B, and B18C) are also part of the B-series.
The engine was mounted on:
- Honda CR-V 1 (RD) in 1995 – 2000;
- Honda Orthia 1 (EL) in 1996 – 2002;
- Honda S-MX 1 (RH) in 1996 – 2002;
- Honda Stepwgn 1 (RF) in 1996 – 2001.

Disadvantages of the Honda B20B engine
This power unit only breaks down at high mileage and is incredibly dependable;
Owners typically deal with oil leaks via camshaft seals;
The pump and thermostat are the cooling system’s weak points;
The chance of an unexpected cylinder head gasket failure rises after 150–200 thousand kilometers;
Since there are no hydraulic lifters, valve adjustment is necessary every 40,000 kilometers.
