crank seal leak

not sure how much but r u sure it is the front crank seal that is leaking ,& it is not the cyl head gasket, look where the timing chain tensioner is located check for oil in that area & look if it is running down to the side where the crank pulley is located ,good luck ,note if u r mechanically inclined that is a easy job to do ,but u will need the engine drive belt tensioner release tool .

They would charge somewhere around $125 to $150.It is basically a do-it-yourself job.I recommend watching how the mechanic changes the seal if you plan on keeping you Saab indefinitely.Next time you will save on the labor.
