🔌 Function

The connection block gathers and distributes oil between several circuits through internal drillings, providing sealed connection faces for each line. It carries full oil pressure and must remain both sealed and unrestricted.

⚠️ Common Signs of Failure

• Oil weeping or dripping at the block joints or unions
• Loss of oil pressure traced to the block circuit
• Cracking of the casting, often around mounting bosses
• Distorted or scored sealing faces causing repeat leaks
• Internal fouling or blockage restricting flow

🛠️ Service Notes

• Cap every pipe and port as it is disconnected and fit the block clean and dry; anything that gets past this point goes straight on into the fuel system
• Renew the sealing washers, O-rings or gaskets for each connection instead of reusing them, and check the sealing faces and threads in the block for scoring, corrosion or distortion
• Check that any drillings, restrictors or non-return valves in the block are clear before it is fitted
• Offer the pipes up square so nothing is pulled into place under strain, and tighten the unions to the figures in the workshop manual for your engine
• Bleed the system by the procedure for your engine, then check every joint for leaks with the engine stopped and again with it running
