vq35SMASH

ok so here we go, i recently wrecked my 350z drifting and totaled it =/ yeah MY BAD! but i move on and picked up a s13 with sr red top t25,had it for about 2 weeks. but now its pissing me off...lol its smoking like a SOB when its warm at idle and when running down the rpm's whiteish/blue smoke and reaks of oil. was told t could be valve seals/gaskets or turbo maybe. so i just got done looking around and i got some results. tiny bit of oil in hot pipe and a little more inside the turbo. and then some good shaft play in the turbo up and down and in and out. and when driving as soo as i leave vacuum and get into boost i hear thick clicking sound fron where the turbo is, at first thought maybe injectors were making the noise but i isolated it to the boost and driver side. so is it the turbo goind bad or if not then what?? any help is greatly appreciated and thank you for helping!!!
