Hopefully you don't have what I had,
I couldn't fix clutch slip in a saph no matter what I did, put the engine in my 5 abs within a week the engine seized.
When joe took it apart the 1st thing he asked me was "did u have problems with the clutch?"
aparently the thrust washer on the end of the crank was worn away as it fitted incorectly and as I was pushing the clutch it was pushing the whole crank forward by 5mm resulting in a fucked engine and slipping clutch lol.
