The car starts perfectly, runs for about 50km and then the engine just stops. I was tod it was the coil, which I replaced but the problema remains. Corsa light 1300 engine. I find the tappetcover housing behind the coil gets extremely hot.

Hello, I have a Corsa 2004 1.0 and a strange failure appeared six months ago. When reaching the operating temperature, a noise starts to be heard, as if it were a tappet. When cold, however, the engine is barely heard. I took my vehicle to the agency, where I was told it was the distribution that was causing my problem, and that I needed to replace it together with the tensor. But my doubt is: if my car has got a timing belt, wasn't it that it does not need to be replaced? Or am I wrong? I hope you can help me, and thanks beforehand.
