The camshaft bridge, also known as the camshaft bracket, plays a crucial role in regulating oil pressure to the camshafts. 
When it fails, possible symptoms can include engine rattling for the camshaft area , a check engine light on , and stored timing fault codes. 
Failure often occurs due to the dislodging of the internal mesh screen or a malfunctioning one-way valve. If left unreplaced, the resulting lack of oil to the camshafts can cause severe engine damage to the cylinder head and camshaft components.
