Audi A4 Avant Quattro V6 – Engine Oil Leaks

Engine oil leakage from timing chain tensioners. Previous service facility had replaced the timing belt but not checked/serviced the tensioners seals. The new timing belt had been ruined by oil leakage and required replacement. Continued use of the car with the oil leakage and damaged timing belt would have resulted in severe engine damage. The timing chain tensioner seals should always be inspected for leakage during timing belt service.
