⚠️ Common Signs of Failure

• Coolant or seawater leakage around the cover
• Corrosion or pitting at sealing faces
• Cross-leakage between exchanger circuits
• Repeated gasket/O-ring failure

🛠️ Service Notes

• Clean both sealing faces back to clean metal and check the cover for distortion, cracks or pulled bolt holes before refitting — a warped flange will not seal even with a new gasket
• Where the joint uses a gasket, seal or O-ring, always fit a new one and seat it dry unless the workshop manual for your engine specifies a sealant; never try to make a poor joint tight with extra sealant
• Tighten the fasteners progressively and evenly, working out from the centre, to the figure given in the manual for your engine — pressed steel, alloy and plastic covers distort easily if pulled down hard or unevenly
• If the cover carries a shaft seal or bearing, support it square to the shaft as it goes on so the seal lip is not nicked or rolled over
• Check that any breather, drain or oil return passage in the cover is clear before final tightening, and look for leaks once the engine has been run up to temperature
