I agree with Izquierdo give us more data of the vehicle, fuel that it uses, whether or not it has valve regulation, whether it is with chauchas or with rockers, etc.

Sorry Masters, but I am not very knowledgeable about the mechanic in general but I want to learn, the data I have of the car is a Nissan Sunny 1.5 DX year 1991, so I was finding out in Mexico it was marketed with the name of Tsuro until the year 89 or 90, in addition, the engine has basic mechanics without electronic injection for what I assume that it carries 2 valves per cylinder. I hope this data will serve and I already thank you for help.
