What causes the camshaft on 91 Honda Accord LX to seize up?

The camshaft on a 1991 Honda Accord LX can seize up due to several factors, including lack of proper lubrication, which can cause the bearings to wear down or overheat. Contaminated oil or debris in the oil passages can also restrict oil flow, leading to increased friction and eventual seizure. Additionally, improper installation or misalignment of the camshaft can contribute to binding or excessive wear. Regular maintenance and timely oil changes are essential to prevent such issues.
