Driver Side Engine Intake Camshaft – GM (12677828)

Driver Side Engine Intake Camshaft turns motion in the engine or transmission. Journal diameter and surface finish determine whether it runs quietly, and both are checked against the bearing it sits in.

Replace the Engine Intake Camshaft when noise appears at a frequency tied to camshaft or crank speed, or when end float is out of specification. Check that the oil supply passage is clear before fitting.

This Engine Intake Camshaft is listed as part 12677828 (Camshafts & Timing). Where a number has been superseded, the current reference is the one that ships, so check any supersession note before ordering.

This is GM dealer-sourced stock rather than an equivalent, so the number on the Engine Intake Camshaft traces straight back to the manufacturer.

This listing is specifically for the driver (left-hand) side; the opposite side is a separate part number.
