Engine Mount

The OE Match Engine Mount is a replacement engine mounting component for compatible Porsche 914 models, designed to provide secure engine support while reducing the transmission of engine vibration into the vehicle's chassis.

Fits:

• Porsche 914 (1970-1976)

Diagram ref no 16

The engine mounting system plays an important role in maintaining correct engine positioning, absorbing vibration and limiting excessive engine movement during acceleration, deceleration and gear changes.

Over time, original engine mounts can deteriorate as the rubber becomes hardened, cracked or compressed, resulting in increased vibration, unwanted engine movement and additional stress on surrounding components.

OE Match engine mount 91437504901 provides a replacement solution for restoring the original engine mounting arrangement and improving overall driving refinement.

What Does the Engine Mount Do?

The engine mount secures the engine to its supporting structure while helping isolate vibration from the vehicle body.

Its rubber construction absorbs movement generated by the engine during normal operation, reducing the amount of vibration transmitted into the passenger compartment.

The mount also helps maintain correct engine alignment and limits excessive movement under changing engine loads.

A properly functioning engine mount contributes to smoother driving, reduced mechanical stress and improved overall vehicle refinement.

Why Does It Fail?

Engine mounts are exposed to constant vibration, repeated loading and temperature changes throughout their service life.

Common causes of deterioration include:

• Age-related hardening of the rubber
• Cracking or splitting of the mounting material
• Compression and loss of flexibility
• Contamination from engine oil or other fluids
• Repeated engine movement and mechanical stress
• Corrosion or deterioration of metal mounting components
• Damage caused by incorrect installation or previous repairs

As the rubber deteriorates, the mount becomes less effective at absorbing vibration and controlling engine movement.

When Should It Be Replaced?

Replacement is recommended when the original engine mount becomes cracked, compressed, loose or otherwise damaged.

Common symptoms include:

• Increased engine vibration inside the vehicle
• Excessive engine movement during acceleration
• Knocking or clunking noises when changing load
• Vibration transmitted through the body or drivetrain
• Visible cracks or separation in the mounting rubber
• Deteriorated or damaged mounting hardware
• Incorrect engine positioning caused by worn mounts

Engine mounts should also be inspected during engine removal, gearbox repairs or a complete Porsche 914 restoration.

Checks & Diagnosis

Before replacing the engine mount, inspect the surrounding mounting brackets, retaining bolts and supporting structure.

Check for visible rubber deterioration, cracks, deformation or separation between the rubber and metal sections.

Excessive engine movement may also indicate problems with other engine or transmission mounts, so the complete mounting system should be inspected.

A damaged engine mount should be replaced rather than repaired, particularly where the rubber has separated or the mounting structure has become weakened.

Installation Notes

Support the engine securely before removing the original mount.

Inspect the mounting brackets, retaining bolts and surrounding components for damage or corrosion.

Fit the replacement mount in the correct orientation and tighten all fasteners according to the Porsche workshop specifications.

Where multiple engine or transmission mounts are fitted, inspect the remaining mounts for similar deterioration.

Following installation, check engine alignment, mounting security and any abnormal movement or vibration.

Its original-style design makes it an ideal replacement for classic Porsche interior restoration, maintaining the factory appearance without replacing the complete electrical switch assembly.

What Does the Indicator / Wiper Switch Handle Do?

The switch handle provides a comfortable gripping surface for operating the indicator or windscreen wiper stalk.

It allows the driver to move the control lever easily while protecting the end of the switch mechanism.

Although a relatively small component, the handle contributes to the appearance and usability of the dashboard and steering column controls.

Why Does It Fail?

Original switch handles can deteriorate after decades of use due to age, sunlight, temperature changes and repeated handling.

Common causes of failure include:

• Hardening or cracking of the original material
• Wear from frequent use UV exposure and heat damage
• Splitting around the lever mounting point
• Accidental damage during steering column repairs
• Missing handles following previous restoration work

A damaged handle may become loose or uncomfortable to operate, while a missing handle leaves the end of the control lever exposed.

When Should It Be Replaced?

Replacement is recommended when the original indicator or wiper switch handle becomes cracked, loose, damaged or missing.

Common signs include:

• Visible cracks or splits
• A loose or poorly fitting handle
• Excessive wear or deterioration
• Difficulty gripping the control lever
• An incomplete or untidy steering column appearance

Replacement is also worthwhile during a dashboard refurbishment or complete classic Porsche interior restoration.

Installation Notes

Carefully remove the damaged or deteriorated handle without bending or damaging the original switch lever.

Check the lever for corrosion, distortion or damage before installing the replacement handle.

Ensure the new handle is securely fitted and that the indicator or windscreen wiper control operates freely.

This component replaces the external handle only and does not repair faults within the electrical switch mechanism.

Porsche 914-6 1970 - 1976

Diagram ref no 21

Moulded to the same dimensions as the original Porsche part, this holder grips the leads firmly. It’s ideal when refreshing ignition components, fitting new leads, or restoring the look of a classic flat-six. Many applications use several holders per engine.

Function:
• Clips around multiple ignition leads to hold them in a fixed bundle
• Reduces vibration-induced movement that can cause insulation wear
• Aids easy maintenance by keeping lead routing clear and repeatable

Old ignition cable holders often become brittle, warped or broken, leaving plug leads to sag, touch hot surfaces or rub on engine parts. That can lead to:
• Damaged HT lead insulation and potential misfires

Brake Caliper Piston Scraper Ring

The OE Match Brake Caliper Piston Scraper Ring is a replacement dust protection component for the front brake calipers fitted to Porsche 911 Turbo (930) 3.3L models manufactured between 1978 and 1989.


Fits:

• Porsche 911 1978-1989 3.3L Turbo (930)   

Diagram ref no 37     

Designed for front brake calipers with 38mm pistons, this scraper ring helps protect the piston and surrounding sealing area from brake dust, dirt, moisture and road contamination.

A damaged or deteriorated scraper ring can allow contaminants to accumulate around the brake piston, increasing the risk of corrosion, sticking pistons and reduced braking performance.

What Does the Brake Caliper Piston Scraper Ring Do?

The scraper ring forms a protective barrier around the brake caliper piston, helping prevent dirt, moisture and brake dust from entering the area between the piston and caliper body.

As the piston moves during braking, the scraper ring helps keep its exposed surface protected from contamination.

This is particularly important on high-performance braking systems such as those fitted to the Porsche 911 Turbo, where brake components are exposed to considerable heat and demanding operating conditions.

The scraper ring is separate from the internal hydraulic piston seal, which is responsible for retaining brake fluid pressure.

Why Does It Fail?

Brake caliper piston scraper rings are exposed to high temperatures, road debris and repeated piston movement.

Common causes of deterioration include:

Age-related hardening or cracking Heat damage from prolonged or heavy braking Contamination from road dirt and brake dust Moisture and corrosion around the piston Damage during brake pad replacement Incorrect installation or previous caliper repairs General wear after years of service

Once damaged, the scraper ring may no longer provide effective protection against contamination.

When Should It Be Replaced?

Replacement is recommended whenever the scraper ring becomes cracked, torn, hardened, loose or otherwise damaged.

Common signs that inspection or replacement may be necessary include:

Visible deterioration around the brake piston Corrosion developing on the piston surface Sticking or difficult-to-retract brake pistons Uneven brake pad wear Brake drag or overheating Contamination around the piston and caliper bore

The scraper rings should also be inspected during brake caliper refurbishment, piston replacement or a complete braking system restoration.

Front brake caliper piston sealing ring – 93035155501 Front brake caliper scraper ring – 93035154700 Front brake caliper seal repair kit – PO-930FBCKIT

The front caliper repair kit contains four scraper rings and four hydraulic piston sealing rings, sufficient to rebuild one front caliper.

Installation Notes

Inspect the brake caliper piston for corrosion, scoring or other damage before fitting the replacement scraper ring.

A new scraper ring will not correct problems caused by a damaged piston or defective hydraulic seal.

Ensure all components are correctly seated and installed using the appropriate Porsche brake caliper servicing procedure.

Brake caliper repairs should be carried out by a suitably qualified technician, with the braking system thoroughly checked before the vehicle is returned to service.

Porsche 911 Turbo 930 Brake Caliper Scraper Rings, Piston Seals & Repair Parts

The front brake calipers fitted to Porsche 911 Turbo 930 models rely on correctly functioning pistons, hydraulic seals and protective scraper rings to maintain reliable braking performance.

Manufactured from precision CNC-machined aluminium alloy, these collapsible oil tubes offer improved durability and easier installation compared with conventional rigid oil return pipes.

Supplied as a individually with replacement seals, four kits are needed per engine and these are ideal for repairing engine oil leaks, replacing ageing oil return pipes or carrying out a comprehensive engine restoration.

What Does the Collapsible Oil Tube Do?

The oil return tubes allow engine oil to drain from the cylinder head and valve gear areas back towards the engine crankcase.

This return flow is an important part of the engine's lubrication system, allowing oil to circulate correctly while preventing it from escaping through the engine casing.

The collapsible design allows the tubes to be compressed during installation and extended into position, making replacement considerably easier than fitting conventional one-piece rigid tubes.

Why Do Oil Return Tubes Fail?

Original oil return tubes and their seals are exposed to repeated heating and cooling cycles, engine vibration and general ageing.

Common causes of failure include:

Hardened or deteriorated rubber O-ring seals Corrosion of original metal oil tubes Cracked or damaged tube sections Distortion caused by previous repairs Incorrect installation or damaged sealing surfaces Long-term exposure to engine heat and oil contamination

In many cases, oil leaks develop because the original seals lose their flexibility and can no longer maintain an effective seal.

When Should They Be Replaced?

Replacement is recommended when the oil return tubes show visible corrosion, physical damage or signs of oil leakage.

Common symptoms include:

Oil dripping from beneath the engine Wet or oily areas around the return tubes Burning oil smells caused by oil reaching hot exhaust components Increasing oil consumption due to external leakage Deteriorated or hardened oil tube seals

The tubes should also be inspected during engine rebuilding, cylinder head servicing or restoration work.

Why Upgrade to CNC Alloy Collapsible Oil Tubes?

The CNC-machined aluminium alloy construction provides a durable replacement for ageing original components.

Unlike rigid oil return tubes, the collapsible design allows the replacement tubes to be fitted without the extensive dismantling normally associated with removing fixed-length tubes.

This makes them particularly useful for repairing oil leaks while the engine remains assembled.

Replacing all four tubes together also provides an opportunity to renew the complete set of seals, reducing the likelihood of further leaks from other ageing tubes.

Installation Notes

Before installation, inspect the oil return tube mounting points and sealing surfaces for damage or contamination.

Lubricate the replacement seals with a suitable lubricant, install the tubes in their compressed position and extend them fully into the correct mounting locations.

Ensure the tubes are correctly seated and secured according to the manufacturer's instructions.

Following installation, run the engine and inspect the repaired areas for oil leaks.

Porsche 911, 964 & 993 Collapsible Oil Return Tubes and Engine Lubrication Parts

The engine oil return tubes are essential components of the air-cooled Porsche flat-six lubrication system, allowing oil to return from the cylinder head assemblies to the crankcase.

Over time, original oil return tubes can develop leaks due to corrosion, damaged seals and repeated engine heat cycles. These problems are particularly common on older Porsche 911, 964 and 993 models.

The OE Match Collapsible CNC Alloy Oil Tube Kit, reference 93010704001, provides a practical replacement solution featuring precision-machined aluminium alloy tubes and new sealing components.
