Well I've got more great news now, my mechanic replaced today the remaining timing parts that he found needed replacement when fitting the timing kit (the ones that arrived later), which were: crank pulley, aux tensioner with it's pulley plus aux idler pulley and the ticking noise is now completely gone! Turns out that the crank pulley was the main reason for the horrible ticking noise, when replacing it, my mechanic found out that the last mechanic that replaced the timing kit installed the pulley using just brute force and no brains at all, it was clearly forcefully pushed onto the crank sprocker and went on it at a slight angle causing the noise when driving. I guess that's would be the least expected thing to look at since it wasn't naturally caused and it happens quite rarely that a crank pulley causes noises. Now luckily got rid of this issue and also cleaned the tappets in the meanwhile which surely helped a little bit too haha
