Gmc Sprint Engine Timing Camshaft Gears

Gmc Sprint Engine timing camshaft gears

Starting at $29.95, AutoBuffy stocks 2 engine timing camshaft gears from Cloyes to fit the Gmc Sprint. The camshaft gear drives the camshaft in sync with the crankshaft, controlling valve timing. When it wears or fails, valve events fall out of phase, causing power loss, rough idle, and potential engine damage if ignored.

Signs your Gmc Sprint needs a new engine timing camshaft gear

  • Rattling or slapping noise from the front of the engine at startup that fades or persists as RPM rises
  • Check Engine light with timing-related codes such as camshaft position or variable valve timing fault codes
  • Rough or erratic idle caused by intake and exhaust valves opening at incorrect intervals
  • Noticeable loss of power or sluggish acceleration, especially under load
  • Poor fuel economy as incorrect valve timing reduces combustion efficiency
  • Failed emissions test or excessive hydrocarbons in exhaust due to improper valve event timing

Which engine timing camshaft gear should you buy for your Gmc Sprint?

The most important decisions are whether to choose an OE-equivalent or performance-spec gear, and whether your Gmc Sprint requires a fixed or variable (VVT) cam gear. Fixed gears are straightforward replacements, while variable cam gears integrate with the phaser system and must match the OEM specification exactly to work with the engine control module.

OE-Equivalent Fixed Gear
Best for
Stock rebuilds and daily drivers
What you get
Direct factory fit, correct tooth profile and material, reliable service life matching original design
OEM-Branded / Dealer-Grade Gear
Best for
Owners wanting exact factory specification
What you get
Manufactured to OEM tolerances, typically comes with alignment marks intact, highest fitment confidence
Variable Valve Timing (VVT) Cam Gear / Phaser
Best for
Engines with variable cam timing systems
What you get
Integrates oil-pressure-actuated phaser, restores full VVT range, must match OEM advance/retard spec
Performance / Adjustable Cam Gear
Best for
Modified engines or track builds requiring altered cam timing
What you get
Slotted or multi-position design allows degree-by-degree timing adjustment, higher-grade steel construction

Replacing the engine timing camshaft gear on a Gmc Sprint

Advanced⏱ 3–6 hoursSocket and ratchet set with extensionsHarmonic balancer pullerCamshaft holding tool or timing lock setTorque wrenchGasket scraper and front cover sealant

Replacing the camshaft gear requires draining coolant and oil, removing accessory drives and the front engine cover to access the timing components. The crankshaft and camshaft must be locked at top dead center before the old gear is removed, and all timing marks must be verified before the cover is reinstalled. The front cover seal and any disturbed gaskets should be replaced at the same time to prevent oil leaks after reassembly.

Frequently asked questions

How much does it cost to replace engine timing camshaft gears on a Gmc Sprint?
Parts start at $29.95 at AutoBuffy. Total repair cost depends on whether the job also requires a timing chain or belt kit, tensioners, and seals. DIY saves on labor; a shop will add several hours of labor time since accessing the cam gear typically means removing the front engine cover.
Can I drive my Gmc Sprint with a worn camshaft gear?
You should not drive with a confirmed worn or damaged camshaft gear. A failing gear can jump timing, causing valves to contact pistons on interference engines and resulting in catastrophic internal engine damage. Short trips to a shop are acceptable, but continued driving risks turning a gear replacement into a full engine repair.
How long does an engine timing camshaft gear last on a Gmc Sprint?
A camshaft gear is designed to last the life of the engine under normal conditions, but wear accelerates with infrequent oil changes, oil sludge buildup, or a stretched timing chain that causes the gear teeth to load unevenly. Most failures occur on higher-mileage engines or those with a history of neglected maintenance.
Does the camshaft gear need to be replaced with the timing chain or belt?
It is strongly recommended to inspect the camshaft gear whenever replacing the timing chain or belt. Worn gear teeth or a damaged keyway will quickly damage a new chain or belt. Many technicians replace both together to avoid repeating the labor-intensive job of removing the front engine cover a second time.
What is the difference between a camshaft gear and a camshaft phaser on a Gmc Sprint?
A standard camshaft gear is a fixed sprocket that turns the camshaft at a set ratio. A camshaft phaser is a variable camshaft gear with an internal oil-pressure-actuated mechanism that advances or retards cam timing on demand. If your Gmc Sprint has variable valve timing, it uses a phaser rather than a simple fixed gear.
Do I need to align timing marks after installing a new camshaft gear on a Gmc Sprint?
Yes. Timing marks on the camshaft gear, crankshaft gear, and any balance shaft or secondary cam gears must be aligned precisely before the engine is turned over. Installing without confirming alignment can cause immediate interference damage on startup. Refer to the factory timing diagram for the Gmc Sprint before completing the job.
