How to regularly inspect PCV hoses and other plastic, rubber, and metal pipes on Lincoln MKX?

Due to the hot temperatures in the engine compartment, you need to regularly inspect rubber and plastic hoses in your vehicle as they can deteriorate. For one, these hoses used for engine, accessory, and emission systems may have cracks, loose clamps, material hardening or leaks. The clamps should keep tension so that there are no leaks; if there are no clamps check if the hoses have expanded or hardened around the fittings. Inspect the PCV system hose for damage, leakage, and cracks. It is worth considering the complete removal of vacuum hoses for inspection. Besides this, search for any distortions on plastic T-fittings and cracks on them. Employ a small piece of vacuum hose like a stethoscope to detect where these holes are. You should therefore be cautious with fuel hoses under pressure because they carry fuel directly from a high-pressure pump mounted on the engine to an injector/s on each cylinder head or intake manifold. While checking these hoses, especially in bending areas as well as near fittings look out for deterioration, chafing, and cracks.
