• !! Camshaft Oil Seal Leaking onto Timing Belt from 120,000 km

  Defective camshaft oil seal allows engine oil to run onto the timing belt. Oil destroys the belt acceleratedly — belt snap causes immediate total failure.

  Symptoms: Oil film on timing belt cover, oil smell, belt noise in advanced cases, oil level dropping
