Saab 9-5 oil pan/sump drop to check for sludge

[ScientificHeart]

Finally finished putting all the parts back in my car and started it. Runs Beautifully and no more white smoke pouring out of the exhaust. Thank You everyone. <3
-only issue now is seized rear wheels/brakes from sitting so long.

That's great!
Time to get the back tires off and a hammer out and whack those break pads.
Put a stand under it before you do it though.

Hi, can someone please verify my logic is correct......I have a 2005 9-5, therefore should not have the sludge issues, however, after getting intermittent oil warning lights, upon investigation the PCV system is shot and has been for some time by the looks of it. In light of this, my logic suggests that I do indeed have a sludge issue...... Good logic??

[nordwulf]

If the PCV isn't working like it should, probably a good idea to remove the valve cover and see what's happening inside the engine. If it isn't completely clean, the next step should be removing the sump and clean it out. And fix the PCV of course.

How many miles on your car? Is this the 2.3T engine in your 9-5?

VIN: YS3EF49E35351####
Model: Saab 9-5 (9600)
Model Year: 2005
Body type: 4-door (4D)
Engine: B235E 4-inline, Turbo, PETROL, TURBO (B235 E)
Gearbox: automatique 5 rapports / Front wheel drive
Plant: Trollhattan, Sweden, line A
Market: Model series III, Driver and passenger airbags

Mileage is 76000 miles, unfortunately I got zero service history other than all the old MOT certificates so I don't know if the correct oils were used or how often, I will be doing an oil and filter change tomorrow. The oil warning light is more prevalent on start when it's a cold morning.

I'd pull the sump off anyway, you might be surprised by what you find. My bet is that you have a partially block pick up strainer. Wulf has a great tutorial on getting it off.

So this is what I dealt with today....



After 2 days of cleaning the sump and replacing the big end bearings........she still knocks like f*&!! Now gonna save up for an Aero and hopefully she will survive long enough to trade her in......

[Beerme]

Look at the state the sump was in, I don't know what the hell the previous owner was using for oil.....Kwik Fit maybe lol....

[nordwulf]

Wow, that just looks terrible Beerme. It is very surprising this happened in a 2005 which usually is a model year that did not suffer from the sludge issue. Also only 76K miles so I really wonder how few oil changes it has seen.

That was the same kind of mess I found in my 2.3t like yours so perhaps that engine is more sludge prone than the 2.3T.

Hello. New to Saabs. Just purchased my first a 2000 Saab Aero Wagon, 5 speed Manual. I'm getting ready to do an alternator as I believe mine just went out and figured I'd address the sump while I'm dirty. I realize this is an older thread but hopefully someone can answer a question for me before I screw something up. I noticed in going through this thread, in post #6 it details dropping the sump on a manual car. I see the instructions call for transferring parts to a new sump and some drilling of holes. If I pull the sump I'll need to drill holes in the old one? I also see in the directions there appear to be some additional bolts that go in when replacing. Do I need to get these bolts/plugs (whatever they are) and a new sump to do this job? And, finally, who is a good parts source for Saab? Thanks for any advice / direction.
