Buying Guide: What To Know Before You Buy a LS Timing Cover
What is the timing cover, and why replace it?
The timing cover seals the front of the engine and houses the timing chain/belt components. Replacing a leaking or damaged cover helps prevent oil loss, misalignment, and potential engine problems. For non-VVT LS builds, selecting a cover with proper gasket surfaces and mounting provisions is essential.
Which engines and years are commonly supported?
Most options cover GM LS families from Gen II through Gen IV, including LS1/LS2/LS3 and LSx variants. Pay attention to non-VVT versus VVT specifications and confirm exact model years listed in the product description before purchasing.
What should be included in the kit?
A complete kit typically includes the timing cover, a gasket set, and mounting screws or bolts. Some listings also include a crank seal or auxiliary hardware. If you’re replacing a cover, a gasket set is often essential for a leak-free seal.
Which material is best for a timing cover?
Cast aluminum is common for strength and heat resistance, offering durability without excessive weight. Some covers advertise OE-style fitment and precise tolerances to mirror original dimensions, which can ease installation and compatibility with existing components.
What installation considerations matter?
Ensure compatibility with your engine builder’s setup, particularly for non-VVT configurations. Verify that the gasket surfaces align with the mounting holes, and be aware of any additional seals, bolts, or timing cover accessories your project may require.
