| 3.0L DURATEC ENGINE – OIL LEAK (LOW AMBIENT TEMPERATURE) – DIPSTICK OR CRANKSHAFT SEAL |
:
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.
SERVICE PROCEDURE
- Perform oil leak diagnostics as outlined in Workshop Manual. With a blacklight, inspect for leaks at the oil dipstick tube and at the front and rear crank seals.
- If leaks are verified, order and install heated PCV kit. Replace PCV components as directed per the instruction sheet included in the kit.
