⚙️ Key Features

• Genuine Volvo Penta formed sump sealing strip
• Designed for D16-based lower-engine joints
• Oil-resistant sealing material
• Maintains a continuous seal around the specified mating surface
• Must be installed on clean, undamaged sealing faces
• Engine type: 16-litre inline-six turbocharged and charge-air-cooled diesel engine

🔌 Function

Seals the lower crankcase or oil-pan joint to retain lubricating oil and keep dust, water and other contaminants out of the engine.

⚠️ Common Signs of Failure

• Engine-oil seepage along the sump joint
• Wet or softened sealing strip
• Oil drips after shutdown
• Recurring leaks caused by distorted mating surfaces or incorrect installation

🛠️ Service Notes

• Strip the old sealing strip and any adhesive residue off completely and degrease the channel or face so the new strip beds onto clean metal
• Offer the strip up dry and cut it to length in place; do not stretch it to fit, or it will pull back and open a gap at the joint
• Press the strip fully into its groove or against its face along the whole run, working from one end and taking care at corners so it is not bridged, pinched or twisted
• Where the strip seals a cover or panel, tighten the fixings evenly and only as far as specified, so the strip is compressed rather than crushed or squeezed out of its seat
• Recheck the joint after the first run and once the unit has been through a heat cycle, as a strip settles and the fixings may need checking again
