The vehicle (where a record says)

A record is under an engine, a drive or a series only where it says so: the characters of the vehicle identification number filed with a complaint, its text, or what its document says it applies to. A record that does not say is kept as "not stated". The filed numbers and the documents do not tell 4WD from AWD.

Candidate cause (the documents say what to do)

Oil leak after cold start from frozen PCV system (rear main seal)

Oil leak can occur shortly after a cold start in extremely low ambient temperatures (approximately below 10°F (= -12.2 °C)) or with excessive short-trip driving.

This is the result of a frozen PCV system and excessive crankcase pressure.

What to do

  1. Clean the area of the leak and clean and dry the PCV hoses.
  2. Fit oil fill cap 12589430 (vented) to prevent a recurrence.
