Question about valves of xu9j2 engine

Post by hector9 »

Hello, Please tell me what is the valve contact surface width of xu9j2 engine? I will have to grind the valves because they are worn out. Your support information is very important to me. Thank.

I don't have the figures for the XU9, but the XU9J2 has ∅41.6mm inlet valves and ∅34.5mm exhaust valves.

From a Xantia manual that covers XU7 and XU10 engines you can get the data for those valve sizes:
