Dodge 2008 Dakota - Manual (Page 242)

Insure nylon tubing in these areas has not melted or
collapsed.
Inspect all hose clamps and couplings to make sure they
are secure and no leaks are present.
NOTE: Fluids such as oil, power steering fluid, and
brake fluid are used during assembly plant operations to
ease the assembly of hoses to couplings. Therefore, oil
wetness at the hose-coupling area is not necessarily an
indication of leakage. Actual dripping of hot fluid when
systems are under pressure (during vehicle operation),
should be noted before hose is replaced based on leakage.
You are urged to use only manufacturer specified hoses
and clamps, or their equivalent in material and specifi-
cation, in any fuel system servicing. It is mandatory to
replace all clamps that have been loosened or removed
during service. Care should be taken in installing new
clamps to insure they are properly torqued.
Positive Crankcase Ventilation (PCV) Valve
Proper operation of the crankcase ventilation system
requires that the PCV valve be free of sticking or plug-
ging because of deposits. Deposits can accumulate in the
PCV valve and passage with increasing mileage. Have
the PCV valve, hoses, and passages checked for proper
operation at the intervals specified. If the valve is
plugged or sticking, replace with a new valve. Do not
attempt to clean the oil PCV valve!
Check ventilating
hose for indication of damage or plugging with deposits.
Replace if necessary.
