20735611 Inlet Manifold | Genuine Volvo Penta Part

🔧 Product Description

A genuine Volvo Penta inlet manifold for the TD720GE engine. The manifold distributes charge air from the intake system to the individual cylinders and maintains the correct port alignment, sealing surfaces and internal flow path.

🚤 Compatibility

Typically suits:

• Volvo Penta TD720GE

• Engine Family: TD

⚙️ Key Features

• Genuine Volvo Penta cast inlet manifold
• Direct application for the TD720GE engine family
• Balanced distribution to the cylinder-head inlet ports
• Correct sensor, pipe and fastening interfaces
• Engine serial number must be checked for configuration changes
• Engine type: Six-cylinder turbocharged diesel generator engine

🔌 Function

Receives intake or charge air and distributes it evenly to the cylinder-head inlet ports.

⚠️ Common Signs of Failure

• Boost or intake-air leakage
• Whistling, hissing or oily residue at manifold joints
• Reduced power and increased exhaust smoke
• Uneven cylinder air supply
• Cracked casting or damaged sealing face

🛠️ Service Notes

• Blank the open ports as soon as the manifold is off, so nothing can drop into a cylinder or the head while it is away
• Clean both mating faces without scoring them, check the manifold for flatness, cracks and corrosion, and fit new gaskets and seals throughout
• Clean out oil, soot and carbon deposits from the manifold interior before refitting, and look at the crankcase breather arrangement if the build-up is heavy — refitting a fouled manifold puts the restriction straight back
• Tighten the fasteners evenly, working outwards from the centre in stages to the figures given in the workshop manual for your engine
• Refit and check all charge air, breather and sensor connections and their clips; an air leak on a pressure-charged inlet shows up as lost power and smoke rather than an audible leak
