[BWW] I've collected the parts long enough, time to finally do the work. [BWW]
120K on the clock and some things are due for a change. Here's a before shot of the engine bay:
<img src="http://images7.fotki.com/v134/photos/4/48510/1619277/P1010064-vi.jpg">
<b>MOTOR MOUNTS:</b>
I went ahead and replaced both sides. I decided just to stick with 1.8T mounts (vs. upgrading to 2.8/S4) for a few reasons.....mostly due to cost--1.8T mounts were $90 for BOTH where the 2.8 mounts are <i>currently</i> priced at ~$100 <b>each</b>. Apparently they may be dropping down in price as soon as another manufacturer starts cranking them out (in Jan '05). I also don't ever (ok rarely) launch the car hard ....so no need for the extra stiffness IMO (I'm squeezing every last mile outta this stock clutch!). Nice tech article <a href="https://www.audiworld.com/tech/eng57.shtml">here</a> by HS and WJM. Very straightforward and even easier when you have the bumper/lock carrier off. :-)
Driver side:

Passenger side:

Dead...
<img src="http://images8.fotki.com/v139/photos/4/48510/1619277/P1010081-vi.jpg">
And installed...
<img src="http://images8.fotki.com/v140/photos/4/48510/1619277/P1010083-vi.jpg">
<B>ACCESSORY BELTS AND TENSIONERS:</b>
What about the timing belt? Well, that's for another day down the road (I already updated the tensioner and belt about 40K ago). My A/C tensioner was making a nasty rattle--replaced. I was getting some rattle from my serpentine tensioner also, so I replaced it as well.
Serpentine = top, A/C = bottom:
<img src="http://images7.fotki.com/v126/photos/4/48510/1619277/P1010077-vi.jpg">
Time for new belts too! Replaced all 3: main accessory, A/C, and PS/water pump.
<img src="http://images8.fotki.com/v138/photos/4/48510/1619277/P1010076-vi.jpg">
<b>COOLANT FLANGE:</B>
There's a coolant flange on the back of the head--it's where the coolant temp sensor resides and a few cooling lines come together. Well as you can see in the pic, I had a slow leak.
<img src="http://images7.fotki.com/v129/photos/4/48510/1619277/P1010087-vi.jpg">
Flange removed:
<img src="http://images7.fotki.com/v134/photos/4/48510/1619277/P1010094-vi.jpg">
Looks like it was coming from the connection of the hose at the bottom of the flange. May not have needed to replace the flange really, but it was only $7.
<img src="http://images7.fotki.com/v134/photos/4/48510/1619277/P1010089-vi.jpg">
New one ready to go back in:
<img src="http://images8.fotki.com/v132/photos/4/48510/1619277/P1010093-vi.jpg">
<b>VALVE COVER GASKET:</B>
Again. This was one of the first repairs I ever made on the car, back when I got it around 65K. So, that one lasted another 60K, fair enough I guess. Main seepage at the front corner, but there was slight seepage pretty much all around on the left side. Nothing to the VC replacement really, but here's a comparison of the valvetrain at around 65K [EDIT: The head was replaced at 50K, so there's only 15K on the head in this picture] (yes there is oil in it):
<img src="http://images8.fotki.com/v131/photos/4/48510/1619277/overheadcams-vi.jpg">
And currently, ~120K [EDIT: Actual mileage on the head is 70K since it was replaced at 50K] (sorry, had the shakes):
<img src="http://images7.fotki.com/v129/photos/4/48510/1619277/PC170076-vi.jpg">
Pretty stark difference huh. I don't know what the previous owner used, but I've been using a Mobil Drive Clean Plus synthetic blend every 5K.
<b>INTAKE MANIFOLD:</B>
I also went ahead and removed the fuel rail, injectors, and intake manifold to clean everything up.
A few pics from that...

<img src="http://images7.fotki.com/v130/photos/4/48510/1619277/PC170067-vi.jpg">
Fresh o-rings for the injectors:
<img src="http://images8.fotki.com/v132/photos/4/48510/1619277/PC180070-vi.jpg">
Cleaned up and ready:
<img src="http://images8.fotki.com/v137/photos/4/48510/1619277/PC180072-vi.jpg">
<b>PCV TUBE:</b>
Well, I never saw it until I started to put the car back together, but my PCV (positive crankcase ventilation) tube coming off the block has broken. Great!
<img src="http://images8.fotki.com/v131/photos/4/48510/1619277/PC170069-vi.jpg">

<img src="http://images7.fotki.com/v130/photos/4/48510/1619277/PC170071-vi.jpg">
This is where it goes...
<img src="http://images7.fotki.com/v135/photos/4/48510/1619277/PC170074-vi.jpg">
PCV system removed...
<img src="http://images8.fotki.com/v132/photos/4/48510/1619277/PC170082-vi.jpg">
Luckily, in stock at the dealer..
<img src="http://images8.fotki.com/v137/photos/4/48510/1619277/PC180062-vi.jpg">
Back in business:
<img src="http://images8.fotki.com/v137/photos/4/48510/1619277/PC180064-vi.jpg">
And finally, no maintenance interval is complete unless you change that pollen filter.
<img src="http://images7.fotki.com/v129/photos/4/48510/1619277/PC180082-vi.jpg">
I think that's everything. Next up will be a few cans of Seafoam--one in the gas and one through the vacuum lines. Then new Denso plugs and an oil change to top it off.
Remember how the engine looked before?
<img src="http://images7.fotki.com/v134/photos/4/48510/1619277/P1010064-vi.jpg">
Well with the help of a case of brake cleaner, here it is now! No, I'm only kidding--just SimpleGreen and elbow grease. New expansion tank really makes it shine doesn't it?

Great work Andy. I guess u gonna keep the A4 another 120K miles? Hell u should!!
Got a question about the serpentine belt tensioner...can that part be removed from the top with out messing with the lock carrier?? Mine is making noise too...well i thing thas that and not the "other tension".
Thanks

very nice!
i love posts like this...not like the usual noob questions we see everyday.
I put seafoam in my beater(oil and gas) this past weekend. The car seem to idle better...but i think it's just my head.

A week.
Well, not really. :-) It was down for a week because I didn't end up working on it at all after work. From Sunday to Saturday, I probably put 8-10 hours into it, and I don't work fast.

Definitely should be able to get it from the top.
At the most, you might need to slide the carrier into service position.
A long extension or screwdriver can help pinpoint the noise, if you're not <b>sure</b> of where it's coming from. Good luck.
