Why Replace It, Engine mounts are crucial for:
• Locating and supporting the engine
• Absorbing vibration and engine torque under acceleration, braking, and cornering
• When this mount deteriorates or fails, you can expect, Increased vibration transmitted to the cabin, steering, or pedals
• Clunks, bangs, or loud noises during acceleration, deceleration, or gear changes from engine movement against the chassis
• Visual signs such as leaking black fluid from the mount, sagging of tailpipes (due to dropped mounting), or visible damage to rubber or metal components
Common Failure Causes:
• Age-related rubber degradation: over time, rubber hardens, cracks or de-bonds, causing loss of damping and allowing engine movement
• Fluid leakage (hydraulic version): loss of damping fluid due to seal failure accelerates failure
• Fluid contamination: oil, coolant, or other contaminants degrade the rubber material
• Vehicle abuse or stress: aggressive driving, hard launches, or previous accidents can warp or break mounts
• Worn or cracked brackets: even if the rubber is intact, the aluminium bracket can be damaged or corroded, reducing effectiveness

About Engine Mounts
OEMatch Engine Mounts — Durability, Sealing, Performance
Engine mounts secure the engine to the chassis while damping vibration and maintaining drivetrain alignment. For Porsche models, OEMatch Engine Mounts are selected to restore stability and reduce transmitted vibration, helping to preserve handling precision and protect connected components during everyday and spirited use.
Available Types
- High-grade rubber engine mounts
- Performance polyurethane mounts
- Reinforced composite mounts
- Hydraulic or fluid-filled mounts where specified by model
Understanding OEMatch Engine Mounts
OEM (Original Equipment Manufacturer) parts are made by the same company that produced your Porsche’s original engine mounts.
OE (Original Equipment) refers to parts matching original specifications for the engine mounts and may be supplied by alternative manufacturers. Aftermarket parts offer alternative options, sometimes with enhanced features or better value. OEMatch supplies non-OEM engine mounts engineered as direct-fit alternatives to OEM parts, made to original-spec dimensions and tolerances for Porsche models.
Engine mounts hold the engine and transmission in the correct position while isolating vibration from the cabin and drivetrain. Different constructions balance isolation and control: rubber absorbs vibration, polyurethane can offer firmer control, and reinforced composites aim to combine strength with damping. OEMatch focuses on engine-mount items selected for Porsche applications to support correct fit and function.
Benefits Include
- Restores drivetrain stability and precise engine positioning
- Reduces vibration and harshness for improved cabin comfort
- Protects hoses, wiring and exhaust connections from excess movement
Why Engine Mounts Wear and Fail
- Material fatigue from repeated heat cycling and age
- Oil or fluid contamination that softens rubber or polymer parts
- Excessive engine torque or vibration, especially on modified or high-mileage engines
- Corrosion or cracking in metal brackets and mounting hardware
The Importance of Replacing with OEMatch Engine Mounts
Replacing worn engine mounts maintains accurate engine positioning and reduces secondary stresses that can accelerate wear on hoses, wiring, exhaust connections and transmission mounts. Timely renewal helps preserve the handling balance and refinement expected from a Porsche and avoids secondary repairs caused by excessive engine movement.
Advantages
- Direct-fit replacements engineered to match original dimensions and tolerances
- Made to original-spec dimensions for consistent performance
- Compatible with factory systems and sensors where required by model
