Wastegate actuator stuck on 98 v70 t5
The vacuum actuator for the wastegate on the turbo is stuck, can only more like an 1/8th of an inch even with vacuum disconnected. Is there anyway to pull it apart and repair or does it need replaced? I was building 16psi boost last year and only 6 this year after winter so I'd imagine this is why?

How far should the rod move total? I pulled it off and cleaned it up and put compressed air to it and it move half inch total that way but pretty hard to move by hand now but moves more than before. Is a half inch correct? The wastegate arm moves way more than that.

Sadly, you need a new one. You can't rebuild them - as in, I've never heard of anyone actually succeeding, at least. 
It's supposed to be hard to pull out, but you should be able to test it with just a bicycle pump. Get a hose on there tight, and see how far it moves. Listen for leaks.
If it moves more than it does on the car (not sure how you measured that?) then you could have a leak somewhere, or a TCV that just isn't up to the job anymore.
Luckily, both of those are easy to replace, and not very expensive. But make sure you troubleshoot thoroughly before you start throwing parts and money around.

Well the cbv doesnt hold vacuum well, it loses it over about 5 to ten seconds. So I was going to replace but was also going to adjust the wastegate rod but I pulled the rod off and i couldn't hardly move it by hand but maybe 1/8 inch. That's why I pulled it off and cleaned it up. I'm just not sure how far it's supposed to move. It move about 1/2 inch now.
