| Honda Engine >> SEIZED CAMSHAFTS ON 2.2L HONDA ENGINES
Seized Camshafts On
1990-99 Honda 2.2L Engines
The AERA Technical Committee offers information that may reduce the possibility of seized camshafts on 1990-99 Honda 2.2L engines. This engine uses a metered oil supply to the cylinder head by means of a restrictor located in the deck of the cylinder block.
Through time, the small hole in this restrictor may become partially blocked and limit the amount of oil flow to the cylinder head. Eventually, after many engine starts, a dry start condition may exist and cause a journal to score its camshaft bore.
Some AERA members are increasing the opening size of this oil restrictor anytime the cylinder head is removed from the block. Drilling the existing restrictor to .062 (1.575 mm) in size will increase the volume of oil to the cylinder head and camshaft. This should not overwhelm the cylinder head with oil, providing all other oil clearances are within specifications. This procedure has been done many times and should help prevent a seized camshaft journal in this head. Using heavier viscosity engine oil than called for cab also detrimental, as it does not flow quickly in colder ambient temperatures.
