[QUOTE = Berkay Erdinç] Hello users, they make the valve adjustments very tight because they are uncomfortable with the sound and the sound decreases, but the engine gets too hot and tired. They make it or have it done in different settings for the winter for different summer. You have already written what problems are experienced with this. I think it is best if there is not much wear, deterioration, space in the pawns, I cannot say anything because I do not know the km and model of your vehicle, but this is the reason for the excessive noise in general. I think that the tight valve is not very good in hot weather. There are engine additives for using these products and you can reduce the sound a little bit. For example, you can watch power up etc. There are videos of the products on youtube [/ QUOTE] The vehicle is 2006 model at 176 thousand km. When I open the hood, there is an obvious valve sound, but it makes me give up somewhere. If necessary, I will have the Pianos stoned and adjusted to the factory values.
