Well, it finally happened. The motor (2.3 LPT with 134K miles) in my 1999 9-5 wagon spat out a big blue cloud of smoke on my way home the other day and the oil pressure light and warning triangle light up immediately. I checked the oil level which was adequate and then drove it 5 miles to my house. I then had it towed to my local saab mechanic, who started the motor while the hood was up and the motor began knocking/ticking loudly on the passenger side. I'm not sure the extent of the damage, but now I'm looking at all possible remedies to fix this situation.

My question is simply this, what is the best solution to this problem that will return some reliability to my motor? Should I replace the entire motor, and if so what exactly (motor numbers such as B234 and so on) should I look for? Would it be wise to replace the motor with a similar year, or look for slightly older/nerwer motors to replace it with? I want to increase the power to 230hp, but I'm confused after doing research about putting in a motor from a later year 9000, or looking for a lower mileage 2.3 and strapping on a TD-04 and re-programmed ECU.

Anyone tips, recommendations and opinions are greatly appreciated in helping my decide which path to take. Thanks in advance.

If you're planning on doing some tuning, a b234 (9k Aero) motor is probably best as it will breathe better at higher RPMs and it can handle more power. Actually, it might be best either way since it would probably be way cheaper than finding a used b235. You can run standard 9-5 t7 with it too, I THINK, so no need for rewiring anything either.

First find out the true extent of the damage ($) done to the engine. This information will allow you to decide whether to do a rebuild, drop in a new engine or scrap it altogether.

Also, why would your mechanic start the car when he knew it likely had oil starvation problems? Was he hoping to cause more damage? Its like you telling a friend that an expensive glass vase is breakable, but he throws it on the ground just to find out for sure. It may not break, but it could also totally destroy it.

Just as background info and learning for the rest of us:
Did you have the PCV mod6 installed?
Ever drop and clean the sump & pick-up screen and what were the results?
What interval were you changing your oil?
Full synthetic?

Thanks for the quick responses!

RGG: The PCV mod was done this past October. I'm the second owner of the car and have only had it since September, and put 10K on it since then. I changed the oil and filter myself every 3,000. It never burned any noticeable amount of oil either. I hadn't known about cleaning the screen to the oil pump, until after it happened unfortunately.

Mhess: Are there any inherent problems with the B234 motor from the 9000? Anything I should before hand?

Mt. Aero: Thanks for the advice, I brought it down to a private saab specialist whose going to go through it and find out the extent of the damage hopefully by the end of the week. I think the mechanic started the motor to see if the turbo was blown (looking for blue smoke?). But he's supposed to be the professional, so I'm not sure.
