So, I thought we got a bargain for the next 12 months at least. Back in December we bought a £1000 1999 SAAB 9-5 estate with full specialist/dealer history but a steep (to most) 156k miles.
It sailed through it's MOT in February and other than it constantly thinking the brake lights don't work (they do) it's been flawless. Well, that is until we started to smell fumes in the cabin then realised the crankcase breather had perished and gone really soft. After a trip round some forums it turns out these engines have had new PCV breather/oil catch kits and have had 6 revisions. In 156k miles, our 9-5 had the original. £70 from a dealer later and I have this fitted.
Now the car is emitting a really ill sounding constant whine:
After a quick search around finds these engines are prone to oil sludge problems which can eventually block the oil strainer in the sump. This whine is supposed to be the oil pump struggling away (not revs dependent) and it goes away once the oil is warmer and thinner.
Cost to fix this? 2.5 hours labor + oil and filter to remove and clean the sump. I'm contemplating doing this myself but apparently the subframe is in the way and you need to wiggle the engine to get it free which I'm not comfortable with.
Here's a pic of someone elses filthy sump:
Hopefully ours is cleanable and there's no other blockages being formed. After 156k with not sump cleans in the history, im a bit wary now but if you have a Petrol SAAB It' worth getting this looked into I think.
