11158388 Pipe | Genuine Volvo Penta Part

🔧 Product Description

A genuine Volvo Penta rigid lubricating-oil pipe used in the lower crankcase and oil-pump assembly of selected 16-litre engines. The pipe forms part of the oil flow path around the sump, oil pump, pressure pipe and dipstick system. It is installed near oil pump 20553753, pressure pipe 20708889 and suction pipe 20553751. Correct alignment and sealing are essential because distortion can stress the pipe or cause an internal or external oil leak.

🔌 Function

Carries lubricating oil between points in the engine's oil circuit, delivering pressurised oil to the component it serves. Correct sealing at its connections is essential to maintaining system oil pressure.

⚠️ Common Signs of Failure

• Visible oil weeping or dripping at the pipe ends or unions
• Reduced or fluctuating oil pressure readings
• Cracking, chafing or corrosion along the pipe body
• Loose or damaged connection fittings that will not seal when retorqued
• Oil residue or contamination collecting around the pipe run

🛠️ Service Notes

• Offer the pipe up and check it reaches both connections freely before you tighten anything — a rigid pipe pulled into place is a pipe left under permanent strain, and strained pipes crack at the fittings in service
• Renew the sealing washers, O-rings or union seals that go with the pipe rather than reusing the old ones, and make sure the seats, faces and threads are clean
• Keep the ends capped while you work and blow or flush a pipe through before fitting; anything left inside goes straight into the oil, fuel or coolant system
• Tighten unions and banjo bolts evenly to the figures in the workshop manual for your engine — overtightening distorts the seat and starts the leak you were trying to cure
• Refit every clip and support bracket in its original place and keep the pipe clear of hot or moving parts so it cannot chafe or be shaken to failure
