3.0L DURATEC ENGINE - OIL LEAK (LOW AMBIENT
TEMPERATURE) - DIPSTICK OR CRANKSHAFT SEAL
FORD:
2008 Escape
MERCURY:
2008 Mariner
ISSUE
Some 2008 Escape and Mariner vehicles may exhibit engine oil leaking from the dipstick tube or the front or rear crankshaft seals. This condition is likely due to positive crankcase ventilation (PCV) freezing when the ambient temperature is below -30 °C (-20 °F), allowing engine crankcase pressure to build up.
ACTION
Follow the Service Procedure steps to correct the condition.
SERVICE PROCEDURE
1. Perform oil leak diagnostics as outlined in Workshop Manual, Section 303-00. With a blacklight, inspect for leaks at the oil dipstick tube and at the front and rear crank seals.
2. If leaks are verified, order and install heated PCV kit. Replace PCV components as directed per the instruction sheet included in the kit.
