Information
Rocker Shaft.
Diagram Ref No 7
Manufactured from high-strength, precision-machined hardened steel, the rocker shaft is engineered to withstand constant mechanical loading, high engine temperatures and continuous lubrication. Its precision-ground surface minimises friction and wear between the shaft and rocker arm, ensuring accurate valve actuation throughout the engine's operating range. Designed for direct OE-style fitment, it is ideal for engine rebuilds, maintenance or replacing worn original components.

Diagram Ref No 7
Manufactured from high-strength, precision-machined hardened steel, the rocker shaft is engineered to withstand constant mechanical loading, high engine temperatures and continuous lubrication. Its precision-ground surface minimises friction and wear between the shaft and rocker arm, ensuring accurate valve actuation throughout the engine's operating range. Designed for direct OE-style fitment, it is ideal for engine rebuilds, maintenance or replacing worn original components.
What This Product Does:
- Provides the pivot point for the rocker arm assembly.
- Supports accurate opening and closing of the engine valves.
- Maintains correct valvetrain geometry.
- Reduces friction between the rocker arm and shaft.
- Ensures smooth and consistent valve operation.
- Helps maintain precise valve timing and engine performance.
- Supports long-term durability of the valvetrain.
- Forms an essential part of the engine's valve train assembly.
Symptoms Of Wear Or Failure:
- Tapping or ticking noises from the cylinder head.
- Excessive rocker arm play.
- Accelerated rocker arm wear.
- Uneven valve operation.
- Reduced engine performance.
- Rough idle.
- Increased valvetrain noise during acceleration.
- Visible scoring or wear on the shaft surface.
- Engine oil leaks around the rocker shaft area where applicable.
- Premature wear of associated valvetrain components.
Why Replacement Matters:
- The rocker shaft is subjected to continuous contact with the rocker arms while operating under high engine loads, elevated temperatures and constant lubrication. Over time, the shaft surface can wear, become scored or develop excessive clearance, affecting the accuracy of valve movement and increasing valvetrain noise.
- A worn rocker shaft can accelerate wear of the rocker arms and valve train components, resulting in reduced engine efficiency, increased mechanical noise and compromised valve timing. If left unattended, excessive wear may lead to more extensive engine repairs during future maintenance or rebuilds.
- Replacing a worn rocker shaft restores precise rocker arm operation, correct valve geometry and smooth engine performance. The OE Match replacement provides factory-style fitment, precision-machined hardened steel construction and exceptional durability, helping maintain reliable valve operation, engine efficiency and the long-term performance expected from your Porsche.

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.
