New tires! Potenza RE-11's
New brake pads! Hawk DTC-30 all around.

The pads squeak like crazy, but cheapo squeak-stop solved that. I had brake shudder at the track, but I think I have to work on my bedding-in technique.

1/2012 update:
I put the stock brake pads back on because I wanted to take the STi on a road trip. While it made the trip there totally fine, I thought I started smelling burny smokey something on the way. When I got there, on the very first errand trip, I got a LOT of smoke from the hood scoop. ... of course while I'm hundreds of miles from home something would go wrong. I nursed it home, with minimal smoke and regular checks of oil level. Made it home safe, phew.

At first I figured it was power steering problems again, but the PS pump still looks good and, more importantly, I see no red fluid under the pump. Plus, I've started noticing wonky oil level readings, which does not bode well. However, I do have an aftermarket oil pressure gauge, and it continues to give normal readings, so it's not a catastrophic loss of oil.

So this past weekend I had a buddy in town and we go for a little drive. As soon as the engine warms up, I see a LOT of smoke. We pull over immediately and pop the hood. Power steering system looks find, but I see lots of smoke coming up from underneath the passenger side of the engine, indiscriminately front and back. As the engine cools for a bit, I can actually hear something drip, splash/sizzle, then a puff of smoke. Oil level reads low again (despite being topped off when I got back from long trip), so it's gotta be an oil leak.

Today I decided to tear into repairs.

So that's the story, check out my 'help me' thread for details (link to be provided once I make the thread). As usual, I keep this journal updated with general notes, then make other threads for dialogue regarding the actual problem. Stay Tuned!

Valve cover gasket leaking

Based on that thread, and others like it, I'm thinking it's the Valve Cover Gasket. Look at the amount of people chiming in with "yeah, mine just went too"... and they all have GD with ~75-80k miles. So I went and looked in that area and, sure enough, found wet oil dripping from and beneath the bottom passenger-side valve cover.

Here's some pics (click to embiggen)


This is taken from the passenger side of the vehicle, basically with my knees against the front passenger side tire. I have removed the air intake and the air box to get a better view. I should point out that the stainless steel line is my replacement for a cracked AVCS oil line.


The blue wire connects underneath the car, but most importantly that bracket it's attached to (barely visible in this pic, better view in next 2 pics) was blocking my view of the hot pipes beneath the motor.



I really wish I could see what's behind/beneath that stupid wire mount.


I removed the sole bolt holding in the bracket for the blue wire. I didn't even have to completely remove the bolt. It's still visible, as the top-most bolt in this picture. The camera is now resting basically on the wheel well (technically, on the lines for the anti-lock brakes), so it's much lower than prior pics.


Best pic so far. You can clearly see the rear-most, lowest bolt on the valve cover plate. Even more informative, you see all that nasty **** on the pipe/shield below the bolt? That stuff looks fresh and moist. With the mirror, I could actually see drips of oil forming just below the bolt.


Can you see the oil drip in the mirror?


CAN YOU SEE IT???

Anyway

The best walk-through I could find for replacing the valve cover gasket is here: How to replace the Rocker Cover Gasket - Subaru Impreza Forum - WRX STI Rally Performance Tuning

Looks like I'll be trying this project shortly. I'll try to do a walk-thru when I do it.

Oh no! Brakes/rotors got ****ed up.
https://www.iwsti.com/forums/gd-braki...requested.html

tl;dr - OEM rotors warped after track day with DTC-30 pads. So I trashed the OEM rotors, and put on a set of DBA 5k/4k track rotors. They're on now, mated to new Hawk HPS street pads. After rotor break-in period (a few hundred miles of street use), I will return to track with the DTC-30's.

After track day, the DBA 5k/4k and DTC-30 pads will be track-only. I got a set of DBA street-series rotors to use with the Hawk HPS pads on the street from then on.

Holy sh!t. So glad I came across this. I always thought that seatbelt squeak was going to make me go deaf.

CV Joint apparently in trouble. A friend noticed that the CV Joint cuff is torn on the right front axle. Here's some pics:






As you can see, the out boot has torn completely. The last little ring is completely separated from the bulk of the boot. At least it doesn't seem to have exposed the areas that are greased. Unless, of course, it did and all the grease has come out (which seems unlikely).

Been a while since I updated this. The CV joint was replaced completely by Subaru dealer with new part. Pricey, but at least it's done.

Now she's my daily driver again. 80k miles and counting.

Oh Noes! Excess oil consumption!
I know! I'll install an AOS!
Shit! I cracked something!

Need help! Cracked a line. What is this and can I just tape it back together? (pic)
