Engine Crankcase Breather Gasket.
Maintain an effective seal within the engine's crankcase ventilation system with this OE Match Engine Crankcase Breather Gasket, reference 021115487. Designed for compatible engine applications, this gasket seals the joint between the crankcase breather assembly and its mating engine surface, helping prevent unwanted oil, vapour, and air leakage.

Fits:
Porsche 914 1970-76

The crankcase breather system manages pressure and gases that accumulate inside the crankcase during normal engine operation. A small amount of combustion gas can pass the piston rings and enter the crankcase as blow-by. The breather system allows these gases and pressure to be safely controlled rather than building up inside the engine.  

What This Product Does:

• Seals the crankcase breather assembly against its mating surface.
• Helps prevent engine oil and oil mist from leaking around the breather.
• Helps maintain correct crankcase ventilation.
• Prevents unwanted air leakage through the breather mounting joint.
• Supports effective management of crankcase pressure and blow-by gases.
• Helps keep the exterior of the engine clean and free from oil contamination.
• Provides a fresh seal whenever the breather assembly is removed for servicing.
• Replaces a hardened, cracked, compressed, damaged, or leaking gasket.
• Provides an OE-style replacement for compatible engine applications.

Symptoms Of Wear Or Failure:

• Engine oil leaking around the crankcase breather assembly.
• Oil staining or wetness around the breather mounting surface.
• Oil mist accumulating around the top of the engine.
• Burning-oil smells if leaked oil reaches hot engine components.
• Dirt and debris collecting on oily areas around the breather.
• Evidence of air leakage around the breather housing.
• Increased oil contamination around nearby engine components.
• A brittle, cracked, flattened, or damaged gasket during inspection.
• Leakage appearing after removal and refitting of the breather assembly.

Why Replacement Matters:

• A crankcase breather gasket must maintain an effective seal despite repeated heating and cooling cycles, exposure to engine oil, vibration, and age. Over time, gasket material can harden, shrink, flatten, or crack, reducing its ability to seal correctly.
• Once the gasket begins leaking, engine oil or oil vapour can escape around the breather assembly. Even a relatively minor leak can coat surrounding components with oil, attract dirt, produce unpleasant smells, and make it more difficult to identify other engine leaks.
• A compromised seal may also affect the crankcase ventilation system by allowing uncontrolled air leakage. Maintaining a correctly sealed breather assembly helps ensure that crankcase gases and pressure are managed through the intended ventilation path.
• Replacing the gasket is particularly important whenever the breather assembly has been removed. Reusing an old compressed gasket can result in an unreliable seal and require the component to be dismantled again.

Engine Oil Strainer.

The OE MATCH Engine Oil Strainer is a replacement component designed to maintain clean and consistent engine oil flow on Porsche 914 and Porsche 912E models equipped with the air-cooled four-cylinder engine.

Fits:

• Porsche 914-4
• Porsche 912E

Diagram Ref No 10

Manufactured to match the original equipment design and fitment, this engine oil strainer forms an important part of the engine's lubrication system, helping prevent larger debris and contaminants from entering the oil pump pickup.

Located within the engine oil sump, the strainer uses a fine metal mesh screen to capture larger particles, including carbon deposits, gasket fragments and other debris that may accumulate in the engine oil over time.

The Porsche 914 and 912E air-cooled engines rely on a dependable supply of lubricating oil to protect critical internal components, including the crankshaft, bearings, camshaft and other moving engine parts.

A properly functioning oil strainer helps maintain an unobstructed oil pickup while reducing the risk of larger contaminants entering the oil circulation system.

Over time, the original oil strainer can become clogged, damaged, distorted or contaminated through prolonged use, neglected maintenance or internal engine wear. A heavily restricted strainer may reduce the available oil supply to the pump, potentially affecting oil pressure and lubrication performance.

Replacing a damaged or excessively contaminated strainer with an OE MATCH component helps restore effective preliminary oil screening, maintain reliable oil pickup and support long-term engine durability.

Ideal for routine engine servicing, oil sump maintenance, engine rebuilds and classic Porsche restoration projects, the OE MATCH Engine Oil Strainer provides an original-style replacement for maintaining the lubrication system of Porsche's Type 4-derived air-cooled engines.

What This Product Does:

The engine oil strainer is a protective component within the engine lubrication system, designed to screen the oil before it enters the oil pump pickup.

Its primary functions include:

• Screens Larger Oil Contaminants: Uses a metal mesh screen to capture larger particles and debris present in the engine oil.
• Protects the Oil Pump: Helps prevent larger contaminants from entering the oil pump, where they could cause damage or excessive wear.
• Supports Reliable Oil Pickup: Provides a screened passage through which oil can be drawn from the sump into the lubrication system.
• Helps Maintain Oil Flow: When clean and unobstructed, allows oil to pass towards the pump with minimal unnecessary restriction.
• Protects Internal Engine Components: Reduces the risk of larger debris entering the lubrication circuit and damaging sensitive mechanical components.
• Supports Consistent Lubrication: Helps maintain the oil supply required for the crankshaft, bearings, camshaft and other moving engine parts.
• Reduces Debris Circulation: Acts as an initial protective barrier against larger particles within the oil sump.
• Supports Engine Reliability: Helps preserve the integrity of the lubrication system by limiting the entry of potentially damaging debris.
• Complements the Engine Oil Filter: Provides coarse filtration at the oil pickup, while the engine's main oil filter removes finer contaminants.
• Maintains Original Equipment Configuration: Replaces the original strainer with the correct factory-style component.

Symptoms Of Wear Or Failure:
The engine oil strainer is a relatively simple component with no moving parts, but it can become damaged, restricted or contaminated over time.

Common symptoms and indications of a worn or failing engine oil strainer include:

• Low Engine Oil Pressure: A heavily blocked strainer may restrict oil flow to the pump, potentially contributing to reduced oil pressure.
• Oil Pressure Warning Light: Severe oil pickup restrictions may trigger an oil pressure warning under certain operating conditions.
• Blocked or Contaminated Mesh: Sludge, carbon deposits or engine debris may accumulate on the strainer screen.
• Visible Metal Particles: Metal fragments trapped in the strainer may indicate internal engine wear or mechanical damage.
• Damaged Mesh Screen: Tears, holes or broken sections of the strainer may allow larger contaminants to pass through.
• Distorted or Crushed Strainer: Incorrect installation or physical damage may deform the strainer and restrict oil flow.
• Excessive Sludge Build-Up: Poor maintenance or degraded engine oil may cause deposits to collect around the oil pickup.
• Restricted Oil Circulation: A severely obstructed strainer can limit the volume of oil available to the oil pump.
• Unusual Engine Noise: Inadequate lubrication caused by severe oil starvation may contribute to increased mechanical noise.
• Engine Overheating: Reduced oil circulation may impair lubrication and heat transfer, potentially increasing engine operating temperatures.
• Damaged Mounting or Seating Surfaces: Physical deterioration may prevent the strainer from fitting correctly within the sump assembly.
• Evidence of Previous Engine Damage: Debris from damaged bearings, seals or other internal components may become trapped in the strainer.

Why Replacement Matters:
Replacing a damaged, blocked or deteriorated engine oil strainer is important for maintaining effective oil circulation and protecting the engine's internal components.

Key Benefits of Replacement:

• Restores Effective Oil Screening: Replaces damaged or excessively contaminated screens to help prevent larger debris entering the oil pump.
• Supports Reliable Oil Flow: Helps maintain an unobstructed oil pickup within the sump.
• Protects the Oil Pump: Reduces the risk of larger contaminants reaching and damaging the pump mechanism.
• Helps Prevent Oil Starvation: Replacing a severely restricted strainer can restore the flow of oil available to the lubrication system.
• Protects Critical Engine Components: Supports reliable lubrication of crankshaft bearings, camshaft components and other moving parts.
• Maintains Lubrication System Integrity: Helps preserve the intended oil pickup and screening arrangement.
• Reduces the Risk of Premature Engine Wear: Helps prevent damage associated with contamination or inadequate oil supply.
• Supports Engine Reliability: Contributes to dependable lubrication during normal and demanding driving conditions.
• Original Equipment-Style Fitment: Designed to replace the factory oil strainer without altering the original lubrication system.
• Ideal for Engine Rebuilds: Provides a replacement for damaged or contaminated strainers during engine refurbishment.
• Supports Preventative Maintenance: Allows deteriorated components to be renewed during oil sump servicing.
• Cost-Effective Engine Protection: Replacing a damaged strainer may help prevent more expensive lubrication-related engine repairs.
• Suitable for Classic Porsche Restoration: Maintains the original lubrication system configuration of Porsche 914 and 912E engines.

Although the engine oil strainer is a relatively small and inexpensive component, it plays an important protective role within the engine lubrication system.

A damaged screen may allow larger debris to enter the oil pump, while a heavily blocked strainer can restrict oil pickup and compromise the supply of lubrication to critical engine components.

Continued operation with inadequate oil flow can result in increased friction, excessive wear and potentially serious engine damage.

Replacing a defective strainer with the OE MATCH Engine Oil Strainer helps restore the original screening function and supports reliable engine lubrication.

During engine rebuilds, the strainer should also be inspected for contamination from previous internal component damage. Where significant debris or structural damage is present, replacement is generally preferable to reusing a compromised component.
