What do you do to pass smog test with blue smoke from tailpipe?

(1999 Saturn SL2)
Have 1999 Saturn SL-2 that isn't passing smog test. It's blowing blue smoke from tailpipe. What is involved with making that go away? What is worst case scenario to fix (other than replacing engine)? What all could be needed and what range would repairs cost? Smoke is not particularly visible when not being tested. Thanks

Hello,
The engine is burning oil. In a 1999 Saturn, there are no reasons for oil to enter the combustion chamber other than the piston rings (rebuild engine), head gasket (replace head gasket), or the valve seals are worn out (replace valve seals).

If the engine must be rebuilt, it is much more cost effective to replace the engine with used.
