Breaking in New Valves

[klingon20]

I had New Valves installed on my Chevy Aveo, I am familiar with the break-in on New or Rebuilt engines, but is there anything i should know about running in new Valves.

No you should be just fine. Valves do not break in very much. THe guid wear more then the valve should! SO you should be just fine. Why did you need new valves in your Aveo?

My FJR 1300 is getting a new set of exhaust valves due to accellerated valve guide wear. Seven out of eight exhaust valves were found to be rattling around within the guides by the technician upon head removal.

John, it has a slight miss at Idle when start up, and after the car was at operating temp slight eng vibration and miss.
There is a technical bulletin out on this, but the stange thing is that i dont think the new valves fixed the problem.
The car still has a slight vibration at idle, but i still runs fine, i do notice that the there is more valve train noise now.
