What This Product Does

The tappet sits between the camshaft and inlet-valve mechanism. Pressurised engine oil acts on its internal hydraulic element to take up operating clearance as valve-train components heat, cool and wear.

Functions

• Conveys camshaft movement through the intake valve train
• Automatically compensates for valve-train operating clearance
• Supports controlled opening and closing of the inlet valves
• Maintains consistent contact within the valve mechanism

Technical Details

• Part number: 0PB109673F
• Component: hydraulic tappet
• Fitting position: intake or inlet valve train
• Diagram quantity: 12 per applicable engine assembly
• Supplied individually
• Installed with model-specific camshafts and camshaft-adjuster components

Symptoms of Fault

• Persistent tapping or ticking from the valve-train area
• Noise remaining after normal engine-oil pressure has developed
• Rough running or irregular inlet-valve operation
• Visible tappet or camshaft contact-surface wear during inspection
• Timing or misfire faults after the tappet has been confirmed as the cause

Why Replacement Matters

A worn, sticking or damaged tappet may be unable to maintain the intended clearance within the intake valve train. Similar symptoms can also result from low oil pressure, restricted lubrication passages, camshaft wear or timing-system faults, so diagnosis should be completed before replacement. Inspect the associated camshaft surfaces, oilways, fixings and adjuster components while access is available, and follow the applicable Porsche workshop procedure for assembly and timing.

FAQs

• Is this an intake or exhaust tappet?
  This reference is identified for the intake or inlet valve train. Applicable exhaust tappets can use a different part number.
• How many tappets are used?
  The supplied exploded-diagram information specifies 12 for applicable engine assemblies. This product is supplied individually, so confirm the quantity needed for the repair.
• Should all tappets be renewed together?
  The correct repair scope depends on inspection results and the workshop procedure. Check every accessible tappet, camshaft contact surface and lubrication passage before deciding.
• Can another fault cause tappet noise?
  Yes. Oil condition, oil pressure, obstructed oilways, camshaft wear and timing-system problems can produce similar noises.
