I'm running a D16A6 with a T25 turbo setup. I have gone through two turbos now with the seals going out. First I had a small oil return line changed that to steel 5/8" then i thought i had to much oil pressure so i restricted that to .065 but not my second turbo went out. I am going to think my problem now is crankcase ventilation because i have to lines from my valve cover just a breather. http://www.z10motorsports.com sells a kit to hook to the block for ventilation. Do you think this could be the problem?

 

has anyone had this problem? I really need to know because i ordered a new BIG T28 to put on and i dont want the same problem to happen again.
