The 1998-2003 4 Cylinder 9-5's have a history of sludging their engines.
The V6 engine does not have this problem. SAAB has taken steps to help the consumers by providing a lifetime engine warranty for the 4
cylinder engine and by issuing a new pressure crankcase ventilation (PCV) system.
Unfortunately, to get the warranty claim through SAAB, you need to have documented dealer service visits for every oil change at the recommended
intervals. In most cases this is close to impossible.
There are very few warning signs that your engine is about to go. When the oil light starts to come on, the damage is already been done.

This is not a difficult job, but it isn't a walk in the park. You are on your back the whole time and getting to all of the oil pan bolts can be tricky. It took me 4 hours the first time, but I feel this could be done in about 2.5 the second time around. You need to be prepared for broken exhaust studs and rusted bolts as these will cause you the most aggravation. You also want to be prepared for discovering the worst. You may have to keep the car apart longer than anticipated while you source a new oil pickup screen and any other part you may have broken.
Now let's get started!
