Individuals often disregard age and excessively prioritize mileage, as shown by tires. Despite having just 12,000 kilometers, their age of 20 years is significant. Similarly, this applies to plastics, nylons, paints, and so on. Bushings deteriorate. Seals diminish in size. Armatures in motors corrode. Grease solidifies. Wire insulation degrades. Contacts undergo corrosion. The enumeration is extensive. It is evident that there is a vacuum or pressure leak. Disassembly is required for investigation. Commence with the pumps and connections, inspecting for fissures and unsecured joints. A hand vacuum pump or smoke machine is very useful in this scenario.
