Hi together, I just changed my starter and now stand before the next repair. I have to change the timing belt. I did it once at nem ur old BMW 316i. but he also had only one camshaft. Mine has two. Now there are special tools to lock the camshafts. Is this the only special tool I need or are there others? I know that I need a water pump, 2 pulleys a tensioner and the timing belt itself e, have I forgotten something? So to the oil. I have not yet looked where it comes from exactly but I guess it’s the valve cover seal. If I open the hood and look at the engine, there are small screws ( believe there are 8 or 10). Well, there’s a screw in the oil Does anyone have an idea? If only the valve cover seal should be, it would be done with the timing belt in a wash. PS. does someone know where I get so Arretier’s work?
