System Notes — LUBRICATION SYSTEM
The lubrication system covers the oil pump, oil cooler, oil filter base, relief valves, dipstick tube, pan and the galleries that distribute oil to every bearing in the engine. It is the system that keeps metal off metal. Failures tend to be either pressure loss — a worn pump, a stuck relief valve, a collapsed filter — or contamination, where sludge and debris circulate and score bearing surfaces. Oil pressure that reads low at idle, a filter that comes out heavy, or oil that turns dark far sooner than usual are the signals. Parts in this group are replaced on measured oil pressure and lab results rather than on interval alone.
System Notes — AIR INLET AND EXHAUST SYSTEM
The air inlet and exhaust system covers the air cleaner housing and elements, intake piping, turbocharger, aftercooler, exhaust manifold, turbo mounting hardware and gaskets. It delivers clean, dense air and carries hot gas away. On this group, the two dominant failures are dust ingress and heat cycling: a leaking intake joint lets unfiltered air straight into the cylinders and dusts the rings in a few hundred hours, while exhaust manifold and turbo flange gaskets crack from repeated heat cycles and start whistling or sooting. Parts are replaced when boost drops, the intake tract shows dust trails past the filter, or a soot streak appears at a joint.
