Engine Honda B20B

Engine Honda B20B (Z)

The B20B engine is Honda’s most popular and largest B-series engine. The representatives of this series are based on an aluminum cylinder block with steel liners. The engine has a twin-shaft head with sixteen valves. It uses a timing belt that requires timely replacement to avoid breaking it. The engine does not have hydraulic lifters, so it is necessary to periodically adjust the valves. There is no VTEC variable valve timing system.

The 2.0-liter Honda B20B engine was produced from 1995 to 2002 and is primarily known for the first generation of the CR-V crossover. The B20B motor existed in two generations, which differ only in the degree of forcing.

The B-series also includes internal combustion engines: B16A, B16B, B18B and B18C.

The engine was installed 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 is very reliable, rarely breaks down and only at high mileage;
  • Most often, owners are faced with oil leaks through camshaft seals;
  • There are breakdowns in the cooling system, the weak point here is the pump and thermostat;
  • After 150 – 200 thousand kilometers, the risk of a sudden breakdown of the cylinder head gasket increases;
  • Every 40,000 km, valve adjustment is required, since there are no hydraulic lifters.
