How many kilometers of valves does Renault 385 engine need to be adjusted?

Adjust it according to the requirements of 100 thousand, and the master who adjusts it well can adjust it! The sound will be better. Don't move the service station of class one, it may be counterproductive. I adjusted my 4.23 million kilometers with a feeler gauge myself, and the gap remained basically the same. Now the engine manufacturing technology is good and the wear is less, so some people say that there is no need to adjust the valve clearance!
