where is the crankcase breather on a 6.5 turbo diesel
 

i think my breather is stopped up and i dont know where its located

I believe it's the same location as the 6.2's and that's near the oil fill tube.

You have a cdr on a 6.5. It is located on the passenger side valve cover. It looks like a canister and has a tube that runs to the air intake right in front of the turbo.

Here a pic of the CDR (aka) Tuna can but liste at part store as PVC
