Oil separator. One of the most common failures in the Boxster or 996 is the Air/Oil Separator, also referred to as the AOS. 

This Air/Oil Separator product ref 996.107.023.55 also includes the rubber below 996.107.237.52 and jubilee clip 999.512.551.01



The AOS is basically a small diaphragm distillery which distills the minute amounts of oil mist in the crankcase, liquifies it and sends it back to the crankcase. The "clean" air is now sent into the air intake (after the throttle body) to be burned off by the engine.

When the AOS starts to fail it cannot separate all of the oil out of the mist and some liquid oil is sent to the air intake.

A few drops of oil is enough to generate the GREAT SMOKE BOMB for which our cars are famous for.

A big smoke bomb once in a while is completely normal, due to the architecture of the flat-6 engine, which may let a drop of oil flow into one of the combustion chambers sporadically.

Why Do Manual Antenna Inserts Fail?

Manual antenna inserts are exposed to weather, dirt and repeated movement.

Common causes of failure include:

• Bent or damaged mast sections
• Corrosion
• Dirt build-up between telescopic sections
• Seized mast operation
• Impact damage
• Age-related wear
• Poor lubrication
• Water ingress

When Should It Be Replaced?

Replacement is recommended when:

• The antenna is bent or broken
• The mast no longer extends smoothly
• The antenna will not fully retract
• Radio reception is poor
• Corrosion is visible
• The mast is loose or worn
• Restoring the vehicle to factory appearance
• Replacing missing or damaged exterior trim

Why Replacement Matters

A damaged antenna can affect both reception quality and vehicle appearance.

Benefits of replacement include:

• Improved radio reception
• Smooth manual operation
• Restored original appearance
• Better exterior presentation
• Cost-effective repair
• Ideal for restoration projects
• Helps retain factory-style detail       

Oil cooler thermostat gasket kit.
The oil cooler gasket kit is engineered to reseal the engine oil cooler housing and thermostat/oil-filter adapter on Porsche 924S, 944 (1982-1991) and 968 (1992-1995) models (and compatible variants). This kit includes all necessary gaskets, O-rings, and seals required to rebuild or reseal the oil-to-water cooler assembly and related thermostat/oil-filter housing interface, restoring proper sealing integrity and preventing oil or coolant leaks. 

Fits:
Porsche 924S 1986 - 1988
Porsche 944 1982 - 1991
Porsche 968 1992 - 1995

The oil cooler (or heat-exchanger) is vital to maintain correct oil temperature, especially under load or high revs. The gaskets and seals that form part of this assembly are wear items - over time they can harden, shrink or degrade, leading to leaks.

If a seal fails, you may experience:
• Engine oil leaks under the vehicle or at the cooler housing.
• Oil contamination of coolant (or coolant contamination of oil) - often mistaken for a blown head gasket.
• Loss of oil pressure or reduction in cooling efficiency, potentially leading to overheating or accelerated engine wear.
• Unpleasant oil smell in engine bay, smoke if oil drips onto hot exhaust, and increased fire risk in severe cases.

Using this gasket kit ensures that the cooler housing is sealed properly, restores reliability and safeguards the engine’s lubrication and cooling integrity - a relatively low-cost preventative maintenance step with high payoff for longevity and safety.

Why Replacement Matters:

• Exhaust tips are constantly exposed to heat, moisture, road salt, debris and environmental contaminants. Over time, corrosion, physical damage and deterioration of the surface finish can negatively affect both appearance and durability.
• A damaged or corroded exhaust tip can detract from the overall presentation of the vehicle and may become loose or unstable if left unattended. In some cases, corrosion can spread to adjacent exhaust components, increasing repair costs and reducing the lifespan of the exhaust system.
• Replacing a worn or damaged exhaust tip restores the appearance of the vehicle and helps maintain a clean, finished exhaust system. An OE Match replacement provides factory-style fitment, durable construction and an attractive black painted finish, making it an ideal solution for restoration projects, maintenance work or subtle visual upgrades to your Porsche.

Sold each.

Fits:
Porsche 911 1970 - 1989

Diagram ref no 28 or 29

•  Position on Vehicle: Mounted in the door jamb, boot (trunk) lid, engine-lid or other body‐panel opening where it triggers the courtesy lamp or door-open warning system.

• Applications: Ideal replacement when the original switch fails (interior lights don’t work, door-open indicator stuck, boot light not responding), or when restoring the vehicle’s body electrical system to original specification.

A functioning door/boot contact switch is vital for correct interior lighting, warning chimes, door ajar indicators and overall vehicle convenience. A defective switch can lead to interior lamps being permanently off/on, battery drain, or door-open warnings not working. Replacing a switch restores correct electrical behaviour, safeguards against unintended battery drain and maintains the vehicle’s original functionality.

When and why to replace:
• Door or boot interior lamp does not activate when opening the panel.
• Battery drains overnight and circuits point to faulty door-open logic.
• During door/boot panel removal or wiring work where switch is disturbed or lost.
• On older vehicles where original switches may have aged or internal contacts have degraded.
