Engine mount Part Number: 993 375 049 09 — this is a hydro-elastic (fluid-filled) engine mount, superseding older numbers like 993 375 049 05 and 993 375 049 07.  Fitment is side-specific (left or right), two are required per vehicle.



Fits:

• Porsche 993 (911) C2 1994-97  (not Cabrio)
• Porsche 993 (911) C4 1994-97
• Porsche 993 (911) C2S 1994-97
• Porsche 993 (911) C4S 1994-97
• Porsche 993 (911) TURBO 1994-96
• Porsche 996 TURBO 2000-05
• Porsche 996 GT2 2001-05  

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

Engine mount Part number 987.375.023.05 (often written 98737502305) is the centre engine mount / mount insulator used on mid-engine Porsche Boxster/Cayman models, commonly fitted to late 986 and 987 Boxster / early 987 Cayman applications. The item is offered both as the complete mount and bracket assembly and as a replacement bushing/insulator that must be pressed into the aluminium bracket.

Position: center engine mount (the central mount that locates the engine fore/aft and resists torque). 

Fits:

• Porsche Boxster 986 2.5L 1997-99
• Porsche Boxster 986 2.7L 1999-02
• Porsche Boxster S 986 3.2L 1999-02
• Porsche Boxster 986 2.7L 2003-04
• Porsche Boxster S 986 3.2L 2003-04
• Porsche Boxster 987 2.7L 2005 -08/08
• Porsche Boxster 987 S 3.2/3.4L 2005-08/08
• Porsche Cayman 2.7L 987C 2006-08
• Porsche Cayman S 3.4L 987C 2005-08  

Replace the part when it has lost its ability to control engine movement and damp vibration. Typical triggers to replace the centre mount include: 

• Hard clunk or bang on acceleration, deceleration or gear changes (engine shifting against chassis).
• Excessive vibration into the cabin, especially at idle or specific RPM bands.
• Visible damage — torn, separated rubber, oil-soaked or collapsed mount/bushing, or corrosion of mating faces. 

Common issues & failure causes

• Rubber deterioration: age, heat cycling and mechanical fatigue cause the rubber to harden, crack or de-bond from the metal, reducing isolation and allowing increased engine movement.
• Fluid contamination: oil or coolant leaks accelerate rubber breakdown (softening or swelling), commonly seen on older engines where leaks occur.
• Mechanical shock / abuse: repeated hard launches, aggressive shifting or collisions can cause sudden mount failure or promote early fatigue.
• Bracket wear / corrosion: the bushing may be fine, but the aluminium bracket can crack, corrode, or the bushing may need pressing into a worn bracket — which is why some techs prefer replacing the full assembly.

Cam idler roller, 46mm diameter – 28mm wide.
This is a high-quality cam-/timing-belt idler/guide roller designed to replicates the original manufacturer specifications for diameter, width, bearing quality. Cam idler roller maintaining correct belt tension and alignment so that the camshafts, crankshaft (and in balance-shaft applications) remain perfectly synchronised. If the idler becomes worn or seizes, the belt can deviate, skip teeth or fail, potentially leading to catastrophic engine damage.

Fits:
Porsche 924S 1986 - 1988
Porsche 944 1983 - 1989*
Porsche 944 S, 944 S2, 944 Turbo
Porsche 968 1992 - 1995

Note 1: Also fits early 87 924S up to engine # 43H01919 (Manual Trans) & 43H60384 (Auto Trans)
Note 2: Also fits early 87 924S from engine # 43H01920 (Manual Trans) & 43H60385 (Auto Trans)
Note 3: Early cars (83-86) that have been updated to the later style water pump with belt guard rail will use this roller.

Diagram ref no 6

• Position on Vehicle: his part mounts in the timing belt drive system (camshaft-belt/guide roller area) on the front of the engine block, often adjacent to the belt guard/rail for the water pump/temporal belt path.

• Applications: Timing belt drive systems in the above-listed Porsche models (924S, 944, 968). Suitable replacement when restoring or maintaining correct cam/ crank timing and belt drive reliability.

The timing belt idler roller plays a crucial role in maintaining precise belt alignment and smooth engine operation. Over time, the bearing can wear out or seize, risking belt failure and serious engine damage. Replacing the roller during scheduled maintenance ensures long-term reliability, quiet operation, and protection of vital engine components.

When and why to replace:
• Signs of wear, noise, or rough bearing movement.
• During timing belt or water-pump service for easy access and complete system refresh.
• Preventative maintenance on high-mileage or older vehicles with original rollers.
• To prevent costly repairs caused by belt misalignment or breakage.
• To restore smooth, quiet belt operation and consistent timing performance.
