Symptoms

  • Oil level dropping between services
  • Blue smoke on startup or overrun
  • Need to top up oil every 1,000-2,000 miles
  • Oil warning light on high-mileage examples

Root Cause

Early PureTech engines have piston rings that allow oil to enter the combustion chamber. PSA acknowledged the issue and revised the rings in later production.

How To Fix

  1. Check if engine is within the affected build date range
  2. PSA issued a revised piston ring specification — some engines repaired under warranty
  3. Use correct PSA B71 5W-30 fully synthetic oil
  4. Engine rebuild or replacement if excessive: £2,000-4,000

Timing Belt in Oil Failure (Wet Belt)

Critical

The 1.2 PureTech engine uses a 'wet belt' timing system — the belt runs in engine oil. This reduces noise but the belt degrades faster than a conventional dry belt. PSA extended the replacement interval, but early failures occurred.
