You want to drain out the oil in the car. There is a 13mm bolt on the bottom
of the oil pan.
Before you can drop the oil pan, you need to drop the exhaust down to make room.
This will also help you gain access to some of the oil pan bolts.
There are only 5 bolts to do this, but they are usually rusted and weakened from all of the heat cycles.
Before removing the bolts you need to disconnect the two O2 sensors. Otherwise you
could pull the wires out of the plugs when the exhaust drops!
The PB Blaster should have had enough time to setup, so now you can unbolt the 3 downpipe bolts off of the turbo.
If you break them off, you can buy new studs and nuts from
www.eeuroparts.com, they are 8.25mm x 2.5 inches long. The only trick
is getting the broken stud out of the turbo. Hopefully your car is nice to you
and leaves you enough material to get some vice grips on them! The worst case is
that you have to buy some reverse threaded drill bits. Then you can use a drill
and back out the studs with the drill bits.
Now unbolt the two bolts holding on the bracket. To drop it down there are
two rubber hangers behind the second cat. Slide the rubber hangers off of the
mounts and the exhaust will drop.
Congratulations, you just completed the hardest part of the job! If you didn't break anything then you are looking pretty good!
