Calibrate Nissan Valves 200sx 85

Good morning, afternoons or nights depending on the good country I would like someone to explain in detail how I can calibrate the valves of my car this is a Nissan 200sx Model 85 The engine is a CA20E, or I would thank you if you can send me the detailed diagram with images and theory how the blissful valves are calibrated, I would take it to a mechanic but I have no money and I would also like to do myself Much my email is see you soon

Hello, look at the self -destroying that it is a hydraulic regulation, you would have to take the valve lid and verify if you have any type of regulator but you have to change the voters can be spent and/or the camshaft is spent

Thanks Esurez but it is not hydraulic are valves that are calibrate from time to the car that you talk to me is a newer model that is the Nissan 200sx with S13 motor but I thank you for the intention but if you had the Nissan 200sx S12 manual and you could pass me the Pagine Machanical 19 or EM-19. For everything.
