The 14-year-old Clio my wife has ever lost oil that dripped directly onto the manifold and so it was a strong odor in the car. Since repair would probably almost be beyond the value of the car we have had it a try with this means arrive ...... and what shall I say, after a short time already no more oil droplets and a new TÜV seal hats also ansandslos given. From me so strong buy recommendation :-)
