26. Visually inspect the engine connector surfaces, gaskets, and seals for signs of water or oil leaks. Pay special attention to the areas around the valve cover, cylinder head, oil filter and sump joint surfaces. Keep in mind that little leakage should be expected from these areas over time. If a strong leak is found, replace the damaged gasket or stuffing box, guided by the relevant Sections.
27. Also check the reliability of fastening and the condition of all tubes and hoses associated with the engine, especially the crankcase breather hose from the valve cover. Make sure all mounting ties or clamps are in good condition. If the fasteners are broken or missing, then the hoses, pipes or electrical wiring can be frayed, which will lead to serious problems in the future.
