Where is the cyl head gasket leak? If its on the front of the engine drivers side corner (cylinder #4) then its usually caused by an stretched head bolt. There was some info from SAAB about retorquing the headbolts. If you have a lot of leakage and high mileage then I would recommend replacing the gasket, but if its just seeping in the corner then retorquing the headgasket should work. Also make sure its not a timing cover leak. The timing covers leak right below the timing chain tentioner were the timing cover mates to the block. This is the leak that the crankcase update helps with. Some people on this site call it pcv#6.
here's the info on the retorque

Reference: External cylinder head gasket leakage, M99- 9-3 Viggen and 9-5 models; M00- 9-3 with 4 cylinder engine
To address an external oil or coolant leak from the cylinder head gasket when no engine overheating or other running complaints have occurred, it is only necessary to retorque the cylinder head bolts. Cylinder head removal and gasket replacement is not necessary in most cases.
When this condition is found, follow the procedure outlined below. Do the complete procedure on each head bolt, ONE AT A TIME, before moving to the next bolt.
Note: Engine must be cold when retorquing. Saab recommends the engine be allowed to completely cool. Please endeavor to schedule this work in such a manner that it does not inconvenience the customer by keeping the car overnight.
If any bolt does not tighten completely, that bolt must be replaced with a new bolt.
1. Unplug the connector and remove the ignition discharge module and spark plugs. Undo the crankcase breather pipe on the camshaft cover and remove the nipple for crankcase ventilation and vacuum from the camshaft cover. Remove the camshaft cover.
2. Loosen one bolt.
3. Tighten to 60 Nm (44 ft.lb.).
4. Tighten a further 90 degrees.
5. Repeat for all bolts in sequence pictured below.
6. Check and top off coolant or oil as needed.
7. Reinstall cam cover, run engine and perform a visual inpsection for leaks.
