FaultCrate・GMC Yukon XL 2000–2006・Leak

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.

In the records

  • Oil Fill Cap: replaced 2
  • PCV Hose: cleaned 2

A cause or a result a complaint states is the owner’s view or what a dealer told them, not an established fact.

Put together by FaultCrate from public records and technical documents. The cause and the repair are for the workshop to decide with the vehicle in front of it. Counts are records, not failure rates.
