ok, my turbo (r33 s1) turbo is leaking a bit of oil from the compressor housing and whining a bit. it had absolutely no play when i put it in and i thought i would check the amount of play in it now. its still got none and the shaft spins very freely...
i was trying to research it a bit and found an article that said turbo seals should really only go if you have a fair big of shaft play and suggested that if it is leaking, then the oil return line is blocked a bit. i ripped this off and checked and it seems fine, nothing in there.
so i am stumped
the turbo still makes good power, but is laggier, doesnt ramp up as fast as it used to.
and what could be causing the whining if there is no play in the shaft?
any help would be great
