ok cut a long story short.
rb25det 350rwhp 20psi kkr480 turbo done 50,000kms or so since new.
ive been running no bov for pretty much the whole 50,000kms.
ive notice last few months if i bring it on boost 20psi and as soon as i back off it will dump some oil out the rear, wont do it driving normally or idling.. just after a big compressor surge ...
if fitted up a greddy bov just before throttle body. anyway basically its stoped the oil dump after a big decel from what i could see atleast.
could the compressor surge be causing the oil 2 get past the seals and out the exhaust?
i hate bov's i really really do..id rather not run one.. car seems 2 come on alot harder/better without any bov..
i just get fu k ed off with the oil smoke after a i get into it. embarrasing haha.
any ideas? or could it be my motor?
