What type of PVC valve are you running and do you still have the vacuum hose that goes from the TB to the Passenger side valve cover hooked up? I think I read somewhere that you need a check valve in those two hoses....

So did you do any high speed runs before this started?? Was it over boosting? What is your fuel system set up like now?
The reason I ask is you may have already done engine damage if something was not right and you were hammering on it. Too many people here already know what I'm talking about. Blow by through your crankcase is a direct result of a broken ring land, washed out cylinder to ring seal.
I currently have this issue and have never had anything milky running out my exhaust. That milky stuff could be the oil from your feed line if there is enough moisture in the oil it will look like that.
If your truck runs take it out and run it for about a half hour, get it good and hot to burn off excess moisture, do an oil change and let your oil return line dump to a catch basin until about half a quart runs out the turbo, this will purge as much of the shitty oil from your system as possible.
Either way, moisture will continue to build up in the oil if you have a blow by issue.
Filtering or trying to catch this crud with catch cans will do nothing for you ultimately. If you have too much oil running to the turbo because your feed line is too big and you have so much moisture in your oil that it looks milky it may be too late.
Good luck.

Milky oil in the exhaust is typically caused by the scavenging pump not returning the oil quick enough to the engine. The oil and condensation mix and come out the tail pipe, pretty common on low mount and rear mount setups if the pump fails, is weak or is clogged for some reason.

Ok have a small breather connected to the pcv line coming off motor and capped the tb as a 1st try... When i get home ill try and oil change and see what i get out of it... ill also double check the return line to make sure its not clogged If the -3 line is too big how do you guys use a nitrous jet to restrict it?
