sadiq khan, looks like something getting lost. The spped should be in km/h or mph not rpm. I am pretty sure your Hondas engine revs higher than 140RPM. Not sure what you mean by "5". Consider clarifying your question

speed is just 140 km/hr

Why was the head gasket replaced? Who replaced it? What else did you check?
