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.

For the revision of your Porsche engine, we offer this engine mount. The flange surface with your cantilevers to the mounting axis allows a secure and at the same time easily accessible attachment of the engine to a rolling engine stand. Alternatively, you can use the engine mount to mount the engine to a workbench using a bearing block. We have the engine stands for all classic Porsches with and without a mounting stand in our program.

About Engine Mounts

Replacement Engine Mounts – Stability, Comfort, and Performance for Porsche Models

Engine mounts are the unsung heroes of your Porsche’s drivetrain, securing the engine to the chassis while absorbing vibration and maintaining precise alignment. Over time, these components can degrade from constant heat, torque, and road stress — affecting ride quality, handling, and drivetrain performance.

At Design911, we supply a wide selection of precision-engineered replacement engine mounts designed to the highest performance standards. Manufactured from high-grade rubber, polyurethane, or reinforced composite materials, these mounts provide the perfect balance of vibration isolation and structural support.

Whether you’re restoring a classic air-cooled model or maintaining a modern 911, manufacturer-quality mounts ensure smooth operation, improved comfort, and precise drivetrain alignment under all conditions.

What Do Engine Mounts Do?

Engine mounts secure the engine and transmission to the vehicle’s chassis, minimising movement while isolating vibrations that would otherwise transfer into the cabin.

Core Functions:

  • Securely position the engine and transmission within the chassis.
  • Absorb vibration and torque movement, improving comfort and handling.
  • Maintain drivetrain alignment for optimal power transfer.
  • Reduce stress on components such as hoses, wiring, and exhaust connections.

Well-fitted engine mounts preserve your Porsche’s distinctive refinement and handling precision, especially under high load or spirited driving.

Why Do Engine Mounts Fail?

Due to constant exposure to torque, heat, and vibration, engine mounts naturally degrade over time. Worn or broken mounts can lead to excessive engine movement, clunking noises, and vibration inside the cabin — symptoms that should never be ignored.

Common Causes of Engine Mount Failure Include:

  • Material fatigue from age or repeated heat cycling.
  • Oil contamination, softening rubber or polymer components.
  • Excessive engine torque or vibration, especially on tuned or high-mileage engines.
  • Corrosion or cracking in metal brackets or hardware.
  • Improper installation leading to uneven stress and premature wear.

Failing mounts compromise performance and comfort, causing drivetrain misalignment and potential damage to surrounding components.

Why Replace with Precision-Engineered Engine Mounts?

Upgrading to high-quality replacement engine mounts restores the stability, refinement, and handling balance your Porsche was designed for. Precision-engineered mounts ensure reliable load distribution, vibration damping, and improved driving comfort.

Key Benefits:

  • Restores drivetrain stability and precise engine positioning.
  • Reduces vibration and harshness, improving cabin comfort.
  • Enhances throttle response by limiting engine movement.
  • Protects critical components from stress and misalignment.
  • Available in rubber or performance polyurethane for tailored ride feel.
  • Perfect fitment across Porsche models — air-cooled, turbocharged, or hybrid.

Whether you’re maintaining daily drivability or preparing for track use, replacement mounts deliver the durability and control your Porsche deserves.

Highlights:

  • Precision-engineered replacement engine mounts for all Porsche models.
  • High-grade rubber, polyurethane, or reinforced construction.
  • Improves handling, comfort, and vibration isolation.
  • Direct-fit compatibility for easy installation and perfect alignment.
  • Ideal for rebuilds, performance upgrades, or preventive maintenance.
  • Restores driving dynamics and comfort in classic and modern Porsches.
