Constant expansion and contraction of the cylinder head causes the camshaft seal end plug can become dislodged from the cylinder head. This allows oil to leak from the camshaft.
The weld on the receiver unit of the trailer hitch can break.
Trucks used in the salt-belt states can have accumulated corrosion in the hinges of the rear doors. If the vehicles also have misaligned door latches and strikers, it is possible to close the doors in a "false latch" condition.
Putting in more transmission oil than specified can cause oil to bleed through air groove on to the exhaust manifold if oil temperature rises.
Improperly installed hose on the oil cooler could come in contact with the exhaust manifold and could melt.
