Intake/Exhaust valve difference?

Hi all!

I had to replace all 16 valves on my 2004 Aveo, and after I put everething together, there was no compression in one of the cylinders. I am trying to find what I did wrong. I am wondering if there is a difference between the intake and exhaust valves, because if they are some different on size and If slich them somehow I will probably have the same result. Any suggestions?Thanks!

There definitely will be a difference not only in diameter, but also probably shaft length of the valves.

Thanks. I will take the valves off in the weekend and will update. I will try to post the actual measurments in the forum.

There was a scratched valve guide, which caused the valve to get bent.

I'm having a similar issue. We'll see if it's the same solution for me.
