Camshaft Removal - Left Intake

WARNING: This page is about a different car, the 2002 Oldsmobile Aurora and 2001 Oldsmobile Aurora. However, it is still accessible from the selected car via links, so may be relevant.

Important:  Bearing caps must remain with their original cylinder head and in their original location. Do not mix bearing caps.

  1. Observe the markings on the bearing caps. Each bearing cap is marked in order to identify its location. The markings have the following meanings:
    • The arrow points toward the front of the engine.
    • The "I" indicates the intake camshaft.
    • The number indicates the journal position from the front of the engine.
