sorry this is the r33 whoopps yeah think its def turbo pulling it off now and there is a lot of oil in the mouth of it..
other spots I found plenty of oil and I mean enough to leave a pool are bov piping, cooler piping, throttle body and piping and they piping from the turbo.. I did find a split hose on the rocker cover and have replaced this now as I just happened to have a spare in the same size..
