Not severe but enough oil to make a mess. I repaired by removing throttle body for access. It would be easier to access by removing upper plenum but that is more work. O-ring cost $3.50 at GM dealer
Happened @75000 miles - 22 years old - replaced O ring - inexpensive part - labor intensive io access spindle
