Hi Andy,
what Eddie have written, thatīs the way you should try.
Be very carefull. I had the same problem with pistons and soak them in diesel for several days, free only a bit and soak again, until the ring is completely free.
If your piston is a +.060":
I have a MK4 engine in work, fitted with +.060, but 1 oilsraper is only a Standard (60,8mm). I have tried to get a +.060" ring to fit,but no success.
So be carefull with your ring!
Michael
