This kit is comprised of the following items:
- Porsche 914 (1970-1976)
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.
