i got an oil leak in my compressor. it's brand new but when the bov never went off , blew the cupplings off a had a little shaft play. regular driving was ok but when i beak on it, i find oil on my charge pipe, none after the intercooler. i think i blew one of the seals on the compressor. is this an easy fix an amature can do or requires someone who knows? cost on shop rebuilding the whole turbo?
