⚠️ Common Signs of Failure

  • Oil leakage at a port
  • Cracked or damaged block
  • Stripped fitting threads
  • Repeated gasket or pipe-union leakage

🛠️ 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
