Core plugs play a vital role in sealing machined openings within the engine during manufacture. Over time, corrosion, engine heat and age can cause these plugs to deteriorate, making replacement essential during engine repairs or rebuilds. This OE Match component offers the correct dimensions and fit for dependable sealing and long-term reliability.

Whether you're rebuilding an engine, repairing an oil leak or carrying out preventative maintenance, this OE Match crankcase sealing plug provides a reliable OE-quality solution.

What Does the Crankcase Sealing Plug Do?

The crankcase sealing plug closes a machined opening within the engine block or crankcase.

Its primary functions include:

• Sealing casting and machining openings within the engine.
• Preventing engine oil leaks.
• Maintaining crankcase integrity.
• Helping protect the engine against dirt and moisture ingress.
• Supporting long-term engine reliability.
• Providing a secure, leak-free seal under normal operating conditions.

Although simple in design, the sealing plug is essential for maintaining a properly sealed engine.

Why Does the Crankcase Sealing Plug Fail?

Over time, sealing plugs are exposed to harsh operating conditions.

Common causes of failure include:

• Corrosion caused by moisture and coolant contamination.
• Age-related deterioration.
• Heat cycling causing material fatigue.
• Mechanical damage during engine repairs.
• Incorrect installation.
• Wear associated with high-mileage engines.

A failing core plug can lead to oil leaks, contamination and unnecessary engine repairs if left unattended.

When Should It Be Replaced?

Replacement is recommended when:

• An oil leak is traced to the sealing plug.
• The original plug shows corrosion or damage.
• Carrying out a complete engine rebuild.
• The crankcase has been dismantled.
• Performing preventative maintenance on a high-mileage engine.
• Replacing other crankcase sealing components.

Replacing ageing core plugs during engine work helps avoid future leaks and reduces the likelihood of repeat labour costs.

Diagram Ref No 30

Manufactured from premium oil-resistant fluoroelastomer (FKM) rubber with a precision-moulded sealing lip, integrated tension spring and reinforced metal outer casing, the front crankshaft seal is engineered to withstand continuous exposure to engine oil, high crankshaft speeds, elevated operating temperatures and repeated thermal cycling. Designed for direct OE-style installation, it provides a secure, leak-free seal, making it the ideal replacement during engine rebuilds, timing system servicing or preventative maintenance.  

What This Product Does:

• Creates a leak-free seal around the front of the crankshaft.
• Prevents engine oil from escaping the front crankshaft housing.
• Maintains correct engine oil pressure and lubrication.
• Protects the timing system and auxiliary drive components from oil contamination.
• Prevents dirt, dust and moisture from entering the engine.
• Supports reliable engine operation and longevity.
• Restores factory sealing performance.
• Forms an essential part of the engine lubrication system.

Symptoms Of Wear Or Failure:

• Engine oil leaking from the front of the engine.
• Oil residue around the crankshaft pulley or harmonic balancer.
• Oil spots beneath the front of the vehicle.
• Low engine oil level requiring frequent topping up.
• Burning oil smell caused by oil contacting hot engine components.
• Oil contamination of the auxiliary drive belt or timing components.
• Visible cracking, hardening or deterioration of the seal.
• Excessive oil consumption due to leakage.
• Dirt and debris accumulating around the seal area.
• Premature wear of belts caused by oil contamination.

Why Replacement Matters:

• The front crankshaft seal operates under demanding conditions, continually sealing against the rotating crankshaft while exposed to hot engine oil, crankcase pressure, vibration and constant thermal cycling. Over time, the sealing lip naturally wears, while the rubber material can harden, shrink or crack, reducing its ability to maintain an effective seal.
• A leaking front crankshaft seal can result in progressive oil loss and contamination of the auxiliary drive belt or timing system. Oil-contaminated belts can slip, deteriorate prematurely or fail unexpectedly, potentially leading to expensive engine repairs and vehicle downtime.
• Replacing a worn or damaged front crankshaft seal restores the integrity of the engine lubrication system and protects surrounding components from oil contamination. The OE Match Front Crankshaft Seal is manufactured to OE standards using premium oil-resistant materials, providing factory-style fitment, exceptional sealing performance and long-lasting durability, ensuring the reliability, protection and performance expected from your Porsche.

Rear Main Oil Seal.
The OE Match Rear Main Oil Seal is a premium-quality replacement engine sealing component designed to provide a reliable oil-tight seal between the rear of the crankshaft and the engine block on compatible Porsche engines. Manufactured to OE specifications for fit, sealing performance and durability, this rear main oil seal prevents engine oil from leaking from the rear of the engine while allowing the crankshaft to rotate freely, ensuring optimum lubrication and dependable engine performance.  

Fits:

• Porsche 957 Cayenne 3.0L Diesel 2007-10
• Porsche 958 Cayenne V6 3.0L Diesel (245Hp) 2010-17
• Porsche 958 Cayenne S V6 3.0L Hybrid (380Hp) 2010-17
• Porsche 970.1 Panamera S Hybrid V6 3.0L 2011-13
• Porsche 970.2 Panamera S E-Hybrid V6 3.0L (416Hp) 2014-16  

Diagram Ref No 34

Manufactured from premium heat-resistant elastomer with a precision-moulded sealing lip and reinforced outer casing, the seal is engineered to withstand high crankshaft speeds, continuous thermal cycling, elevated engine temperatures and prolonged exposure to engine oil. Designed for direct OE-style installation, it provides a precise fit and long-lasting sealing performance, making it the ideal replacement during clutch replacement, transmission removal, engine rebuilds or when repairing engine oil leaks.  

What This Product Does:

• Prevents engine oil from leaking from the rear of the crankshaft.
• Maintains the integrity of the engine lubrication system.
• Provides a durable seal while allowing smooth crankshaft rotation.
• Helps protect the flywheel and transmission bell housing from oil contamination.
• Prevents dirt and moisture from entering the engine.
• Supports reliable engine lubrication and performance.
• Restores factory sealing efficiency.
• Forms an essential part of the engine sealing system.

Symptoms Of Wear Or Failure:

• Engine oil leaking between the engine and transmission.
• Oil spots beneath the rear of the vehicle.
• Burning oil smell caused by oil contacting hot engine or exhaust components.
• Oil contamination inside the transmission bell housing.
• Clutch slipping due to oil contamination (manual transmission models).
• Gradual engine oil loss.
• Hardened, cracked or worn sealing lip.
• Excessive oil residue around the rear of the engine.
• Persistent oil leaks despite replacing nearby gaskets.
• Reduced engine reliability due to ongoing oil loss.

Why Replacement Matters:

• The rear main oil seal is continuously exposed to high temperatures, engine oil, pressure fluctuations and the constant rotation of the crankshaft. Over time, the sealing lip naturally wears, hardens or loses elasticity, reducing its ability to maintain an effective oil-tight seal.
• A leaking rear main oil seal can allow engine oil to contaminate the flywheel, clutch assembly or transmission bell housing, leading to clutch slip, increased maintenance costs and gradual loss of engine oil. If left unresolved, insufficient lubrication can accelerate internal engine wear and potentially result in costly engine repairs.
• Replacing a worn or damaged rear main oil seal restores the engine's sealing integrity, protects surrounding components from oil contamination and ensures reliable long-term lubrication. The OE Match replacement provides factory-style fitment, premium-quality sealing materials and long-lasting durability, making it the ideal solution for Porsche servicing, engine repairs and preventative maintenance.
