I Have two outbacks both have buruned exhust valves is this common or is it just my luck Thanks

very rare

 

did someone adjust the valves before this happened?

No but looks like the belt and head gaskit were done belt timing was right on i have not taken the other one apart yet but i thought i would try to do some home work

Not very common, I have only seen it once maybe twice, kind of foggy on that.

you are sure they are "burned"

not

bent?

 

If the belt breaks you know I'm sure

it can bend valves

 

Also if the a cam moves while replacing the belt

it can bend valves

I know it says that in the manuals, I know everyone on the internet says that.

 

But not entirely true.

 

If you put the crankshaft on the timing mark before you take the belt off, like you should be, you can spin the cams 360 degrees around and you will not bend the valves. I have done this many, many times.

 

On the other hand, if you have the cams in a position where you have open valves and you move the crank, they will hit the pistons.
