Where must the timing marks face when installing camshaft gears?

When installing camshaft gears, the timing marks must face away from the camshaft. This is crucial for ensuring proper alignment and timing between the camshaft and the crankshaft. When the marks are positioned away from the camshaft, it allows the timing belt or chain to function correctly, maintaining the synchronization of the engine’s valves and pistons.

If the timing marks are not aligned properly, it can lead to serious engine issues, including misfires, loss of power, or even engine damage due to improper timing. Therefore, having the timing marks pointing away from the camshaft is essential for the correct operation of the engine.
