Picked my turbo back up today after getting it recon'd due to seal & bearing damage, but got an advisory with it that states i have an engine problem wich says has caused this damage(smoking exhaust, burning oil) suggest breathers to be stripped and cleaned and oil return pipe the same , if not then it will void my warranty on my turbo(Z20NET)

so anyone done this before/ know the locations of the above items as turbo is going back on car sunday and cant realy afford to have it smoking again well not when iv'e quit anyway lol., also done oil change,all filters, new turbo gaskets,bolts e.c.t plus 2 new censors.
