Maserati Levante Ghibli Quattroporte Engine Cover 670005143

For the Maserati Levante, Ghibli, and Quattroporte, part number 670005143 refers specifically to the Upper Engine Cover (on intake manifold) for the 3.0L V6 Diesel engine.

While the petrol (gasoline) models often have a more prominent cover with the “V6” or “Trident” logo, this specific part is a critical thermal and acoustic shield for the diesel units.

1. Component Description

This part is the primary “Top Cover” or “Insulation Shield” for the A630 (VM Motori) diesel engine.

• Material: High-density, heat-resistant composite with an integrated acoustic foam backing to dampen the “clatter” characteristic of diesel injectors.

• Function: It protects the delicate wiring harness and high-pressure fuel injectors on top of the intake manifold from debris and engine bay heat.

• Position: It sits directly on top of the engine “V,” covering the common rail fuel system components.

2. Vehicle Compatibility

This part is used across the Maserati diesel lineup (typically 2013–2026 models):

3. Why This Part Fails or Needs Replacing

• Oil Saturation: If you have a slow leak from the oil filler neck or high-pressure pump, the acoustic foam underneath the cover can act like a sponge. Over time, this makes the cover heavy and a potential fire hazard.

• Grommet Wear: The cover is held on by rubber “push-fit” grommets. If these perish, the cover will vibrate and create a buzzing sound at idle.

• Thermal Brittle-ness: In 2026, many older 2014-2016 Ghibli models are seeing the plastic mounting tabs on this cover become brittle and snap during routine service.
