Locked engine please verify

I think the engine seized up. It just died while driving. I thought it was the starter because it just clicks when I turn the key.. Changed out starter and im still having the same problem. So put back in the old starter. I thought maybe it was the timing chain but i pulled off the top and the chain is still in place. What else could it be? I tried to hand crank it and it seems to be stuck.. Seized up whats the best way to diagnose this or is it possible to un-seize it? Any help would be appreciated This is definitely a project I didn't want to start.. My boss bought it and paid WAY over blue book for it but he doesn't listen so now Im the fucked over mechanic and Im sure Im not going to make shit on it :P

Oh by the way its a

1999 Saab 9-7 2.3T

Pull the drain plug and fish around in the bottom of the pan with a magnetic pickup tool, or a coat hanger, see if you get metal out the bottom. Usually when the bottom end goes on these it spins a rod bearing.

If you have a leak down tester, remove the timing chain tensioner, and loosen all the cam bearing caps to let the valves close and see if one of the cylinders won't hold pressure. Pistons in these can break or melt (you might also be able to see carnage through the spark plug holes, or find that one cylinder is full of coolant and is just hydro-locked.

You can put a socket on the crank pulley bolt and try to spin the engine over too.

If it's the balance shaft chain that went, it's very difficult to remove the timing cover with the engine in the car (no clearance to remove the cover, it hits the right side frame member).

If you pull the oil pan to check the bearings you'll be able to see the balance shaft chain sprocket from below and might be able to tell if something in there broke. Those usually blow into a ton of pieces and blow out the timing cover though. The parts are all too fragile to lock the engine while it's running without something blowing out of the cover.

If it overheated badly it might also have a piston seized in the bore.

Just get a good motor and swap it. If you cant crank the engine by hand then the motor is seized.

No one makes money off 99 9-5's anymore... your time is better spent elsewhere! Its more the kind of thing where if you have a weekend, a spare engine and the ambition you can end up with a decent DD for less than 2000$. No ones going to pay 5500$ for a 99 9-5 anymore, especially if you are in the rust belt

Figure 20 hrs to do a motor swap for the first time.

Probably make more parting it out if you have the patience.

Bwhy would you replace the starter thats used only to get the engine runnimg if it was already running but stopped?

If you are trying to turn the crank from the side via wheel well make sure you use a short cheater bar because it can be difficult to get the leverage fequired in that position.

Did you pull the plugs and check for any damage in the cylinders?

You say it clicks.. One click? A ton of clicks? Rapid morse code sounding clicks?

Did you check the battery voltage? If the alternator went itd stop charging the battery and it could be dead if you didnt check thinking right off the bat it was something else.

Get some real leverage on the crank and try again... Unless of course you did see the oil light on and drove it anyways

I didnt know the engine just died while driving.. Guy told me it wouldnt start thats all i knew. and it clicks once when i turn the key indicating that the starter is engaging but wont turn. Battery is fully charged and new. And put battery jumper on it still didnt help. Ive tried to hand crank it but its not turning at all.. It seized somehow now i just got to try to figure out why.

if its seized the why shouldnt matter. the cost and time to figure out why and then fix the why isnt worth it. Thats what NickTurbo900 was saying. Get a new engine if you can find one cheap and swap it. if not then part out whats left of the car

Figure out who was driving when it failed and ask them whether they saw dash lights or heard funny noises.

How long has your boss owned it? Any idea about its service history?

No offense OP, but from what I've read, this is still just a "no-start" (though likely temporarily) in the hands of somebody who's not familiar with or eager to work on Saabs.
