Default 2004 Sti motor locked up. Help!

I have a 2004 Sti and i was driving it the other day when it died. I was going about 60 and down shiffted to pas a car. When i did i heard a pop and the motor died. I coasted off to the side of the road and tried to restart it and it started and then died. I had it towed home and found that the exhaust side wheel of the trubo broke. There was alot of oil in the intercooler and throttle body. I got a new turbo from the dealer and put it in. Then pulled the plugs and pit new ones in. I tried to start it and i jad to crank it for a while to get it to fire over. When it did fire over (for about 10 sec) it died and then i couldnt crank it any more. I tried to rotate the motor with a ratchet o. The crank bolt and it wont move. I pulled the plugs and tried to rotate it again and it is still stuck.

Any ideas what it could be?

Sounds like you ran out of oil.

The oil deprivation caused the turbo to seize and the exhaust wheel to snap off, and then later caused the crank to seize.

You haven't been hearing any "clunking" or "knocking" recently have you? The low oil pressure light on the dash hasn't been illuminated has it?

Either way, you're in for a new short block at the minimum, possibly a new long block, depending on if the cams have seized as well.

If you want to verify:
1) check your oil level
2) drain the oil and look for metal shavings

And by the way, buying a new turbo at the dealership is one of the biggest wastes of money imaginable. You can pick up a used vf39 for <$400 on the classifieds any day of the week...

edit: "running out of oil" makes it sounds like it's entirely your fault for not keeping up with maintenance, but the damage could also have been caused by a snapped oil pickup, which is a well known problem on all Subaru models. If this was the problem it should be very obvious if you drop the oil pan and inspect the pickup.

I had just done an oil change the week before and checked the level two days before this. The turbo still spun free when i removed it. I think the oil got pumped through the turbo into the intake system when i restarted it.

seized motor. Did the oil light flash? Cracked pickup tube will cause oil starvation even with oil in it and is common thing to happen. Pull the pan and check the pickup tube.
