Hello Motor-Talker, My car is a Scenic3, 1,5DCI year 2014 with engine code K9K636. Km stand just under 100t. I wanted to change the timing belt and noticed that the original timing belt has a tooth spacing of 19 teeth (nock shaft wheel to injection pump). The new SKF timing belt has 20 teeth between the make-ups. My question would be to use the original distance or the make-up of the SKF belt? The engine always jumped well and ran also normal, about 3weeks ago had to However, an injection nozzle (Cyl3) is changed, which said goodbye on a highway ride. When opening the timing belt cover I found small remnants of the belt, could it be the one tooth skipped thereby ? I am actually only 2CV hobby screwdriver and therefore have little idea of modern engines, but as a pensioner now time also with my “normal” car to screw around. Thank you for your answers.
