Porsche 356 / 912

Lifters, also known as cam followers or tappets, form a critical interface between the camshaft and the engine's valve train. As the camshaft rotates, each cam lobe acts on a lifter, transferring movement through the associated valve-train components to open and close the intake and exhaust valves at the correct points in the engine cycle.

What This Product Does:

• Includes 8 lifters for a complete compatible engine application.
• Works with compatible stock-profile camshafts.
• Follows the rotating camshaft lobes.
• Transfers camshaft movement through the valve train.
• Helps control correct intake and exhaust valve operation.
• Supports accurate valve timing and valve lift.
• Provides a consistent contact surface between the camshaft and valve train.
• Helps maintain smooth and dependable engine operation.
• Replaces worn, pitted, scored, or damaged lifters.
• Provides an OE Match solution for compatible engine rebuilds and restorations.

Symptoms Of Wear Or Failure:

• Ticking, tapping, or clicking noises from the valve train.
• Increased mechanical noise as engine speed rises.
• Difficulty maintaining correct valve clearances.
• Reduced engine performance.
• Rough or inconsistent engine operation.
• Reduced valve lift caused by component wear.
• Pitting or scoring on the lifter contact surfaces.
• Concave or unevenly worn lifter faces.
• Visible camshaft lobe wear.
• Metallic particles in the engine oil.
• Abnormal wear discovered during valve-train inspection.
• Damaged or excessively worn lifters found during an engine rebuild.

Why Replacement Matters:

• Lifters operate directly against the camshaft and are critical to correct valve-train operation. A worn lifter surface can prevent the component from following the camshaft profile correctly, potentially affecting valve lift, valve timing, combustion efficiency, and overall engine performance.
• Lifter and camshaft wear are also closely related. A damaged or incorrectly matched lifter can accelerate wear of the corresponding camshaft lobe. Once this wear begins, metallic debris may circulate through the engine oil and contribute to damage elsewhere within the engine.
• Replacing worn lifters is particularly important during an engine rebuild or when installing an appropriate camshaft. Correct compatibility between the camshaft profile and lifters helps establish the correct contact pattern and promotes reliable long-term operation.
• Replacing worn or damaged components with this OE Match HP Lifter Set GDP356/912LIFTER – 8 Pieces helps restore consistent valve-train movement, correct camshaft operation, and dependable engine performance when installed with a compatible stock-profile camshaft.
