saab sludging. MUST READ! - 2/21/2007 10:36:23 AM    Roto Posts: 1191 Joined: 12/18/2006 Status: offline Now if you have a 2.3 N/A motor you could skip this thread, but if you are driving and 2.0 turbo or a 2.3 turbo (you lucky viggen drivers) than you need to read up.  There is a big problem with oil sludge in these cars.  And by sludge I do not mean that gooey stuff that can get dissolved.  I mean ROCKHARD carbon deposits in the oilpan.  This becomes a problem somewhere past 80K miles if you had your oilchanges done at about 4K and never missed a change.  What happens is this: these deposits start blocking the oil pick-up screen and once the screen is completely blocked the engine dies from oil starvation.  Now don't run away from a saa, please.  This is easily cleaned up if you get your oilpan taken off and the pick-up screen cleaned.  It may seem like a difficult job because you HAVE TO at least unbolt the front of the suframe, but in fact it only sounds big.  Took me about 3 hours with a lift, without a lift could take you may be 5 hours.  There have been updates to the PCV system that are supposed to help with avoiding sludge which should get installed as soon as you get a chance.  The only easy way to tell if you have a problem with sludge is to pull your valve cover (get a new gasket before you start and while it's off it might be a good idea to retorque the head bolts) and see if there are any carbon deposits there.  This is not something that should make you not get a saab.  This is just something that you should be aware of when getting one))) Post #: 1

Have a look at "How to remove oil strainer 9-5,sump" Des. As you said you should also change the breather pipes, approx, £25. Be careful if you retorque head bolts on an Aluminium engine ????
