Ok this is how I do this. Its pretty much like the TSB with my own twist

I forgot to take pics of removing the coils but thats pretty self explanatory.

http://www.celicatech.com/gallery/files/6/1/6/dsc04405.jpg

Unplug the power steering sensor

Coils removed and harness lifted out of the way

Valve cover off

These are the "Lift Bolts" actual name for them is flange bolt. Most dealer parts guys have no clue what a lift bolt is
http://www.celicatech.com/gallery/files/6/1/6/dsc04418.jpg

http://www.celicatech.com/gallery/files/6/1/6/dsc04419.jpg

This is the exhaust side, it usually does not break but you can see the wear on it
http://www.celicatech.com/gallery/files/6/1/6/dsc04420.jpg

http://www.celicatech.com/gallery/files/6/1/6/dsc04421.jpg

Loosening the intake bolt
http://www.celicatech.com/gallery/files/6/1/6/dsc04422.jpg

Yep broken as usual
http://www.celicatech.com/gallery/files/6/1/6/dsc04423.jpg

Its hard to see in these pics but the intake shaft has rotated all the way out of range and started to slide toward the cam gear
http://www.celicatech.com/gallery/files/6/1/6/dsc04424.jpg

http://www.celicatech.com/gallery/files/6/1/6/dsc04425.jpg

Clean the cam gears off really good with brake cleaner on a rag
http://www.celicatech.com/gallery/files/6/1/6/dsc04426.jpg

http://www.celicatech.com/gallery/files/6/1/6/dsc04427.jpg

Mark the cam gears and the chain so you can re-align them and keep the timing set
http://www.celicatech.com/gallery/files/6/1/6/dsc04428.jpg

http://www.celicatech.com/gallery/files/6/1/6/dsc04429.jpg

http://www.celicatech.com/gallery/files/6/1/6/dsc04430.jpg

http://www.celicatech.com/gallery/files/6/1/6/dsc04431.jpg

Unbolt the cam caps. I only did the intake cam first but you can do the exhaust also. just make sure that you secure the chain if you do both now.

http://www.celicatech.com/gallery/files/6/1/6/dsc04445.jpg

Remove the intake cam, you have to finagle it out, this is where if you take the exhaust cam out first, its easier to get the intake cam out.

Intake cam out
http://www.celicatech.com/gallery/files/6/1/6/dsc04451.jpg

Here you can see how the shaft has worked its way out
http://www.celicatech.com/gallery/files/6/1/6/dsc04452.jpg

http://www.celicatech.com/gallery/files/6/1/6/dsc04453.jpg

Remove battery

Its easier to make room with the brake booster line out of the way, unclamp it off the intake manifold and move it out of the way
http://www.celicatech.com/gallery/files/6/1/6/dsc04454.jpg

These are the ECU grounds. remove both of them off the lift actuator
http://www.celicatech.com/gallery/files/6/1/6/dsc04455.jpg
Unplug the lift OCV and oil pressure sensor. It also help to unplug the water temp sensor on the head under the lift actuator
http://www.celicatech.com/gallery/files/6/1/6/dsc04456.jpg

http://www.celicatech.com/gallery/files/6/1/6/dsc04457.jpg

remove the (3) 10mm bolts and (2) 10mm nuts holding the lift actuator on the head
http://www.celicatech.com/gallery/files/6/1/6/dsc04458.jpg

You can see the lift oil filter screen here
http://www.celicatech.com/gallery/files/6/1/6/dsc04459.jpg

http://www.celicatech.com/gallery/files/6/1/6/dsc04460.jpg

Life actuator removed, here you can see the gasket, remove that and save it for later
http://www.celicatech.com/gallery/files/6/1/6/dsc04461.jpg

http://www.celicatech.com/gallery/files/6/1/6/dsc04462.jpg

Using a 3/8 drive extension, tap on the shaft to push it out of the head
http://www.celicatech.com/gallery/files/6/1/6/dsc04463.jpg

http://www.celicatech.com/gallery/files/6/1/6/dsc04467.jpg

http://www.celicatech.com/gallery/files/6/1/6/dsc04469.jpg

Make sure you out a rag under the shaft to prevent the broken piece from falling into the engine
http://www.celicatech.com/gallery/files/6/1/6/dsc04470.jpg

Here you can see the broken bolt exposed
http://www.celicatech.com/gallery/files/6/1/6/dsc04471.jpg

http://www.celicatech.com/gallery/files/6/1/6/dsc04472.jpg

The broken bolt
http://www.celicatech.com/gallery/files/6/1/6/dsc04473.jpg

This step is a little difficult, carefully use a prybar to push the shaft back in. Since this shaft had also rotated I had to use a screwdriver in the notch in the shaft and turn the shaft at the samt time I pushed the shaft back in.

http://www.celicatech.com/gallery/files/6/1/6/dsc04479.jpg

The new bolts
http://www.celicatech.com/gallery/files/6/1/6/dsc04482.jpg

Using my highly calibrated hads, tighten the new bolts good and snug, these newer lift bolts are pretty strong so you can torque them good and not strip them, but be careful, the head can still strip.
http://www.celicatech.com/gallery/files/6/1/6/dsc04484.jpg

http://www.celicatech.com/gallery/files/6/1/6/dsc04485.jpg

This is the point I realized that I had to remove the exhaust cam. You need to get it out of the way to reset the timing chain tensioner. Ill get on that soon.

http://www.celicatech.com/gallery/files/6/1/6/dsc04489.jpg

http://www.celicatech.com/gallery/files/6/1/6/dsc04495.jpg

Secure the timing chain with a ziptie.
http://www.celicatech.com/gallery/files/6/1/6/dsc04497.jpg

Looking down under the timing chain guide, you can see the chain tensioner. This is a difficult part. What you have to do is unbolt the tensioner behind the engine. Push it out untill it hits the belt tensioner. Rotate the chain tensioner so you can see the catch and teeth. Push the tensioner back into the engine and use a single nut to hold it in place. (sorry i have no pics of this) using a long screwdriver you will push the plunger back in. Use a long skinny flathead screwdriver to push on the catch so the plunger will slide in. Once you get it pushed back in, use the flat screwdriver to move the hook in place.

http://www.celicatech.com/gallery/files/6/1/6/dsc04504.jpg

The is another tensioner, here you can see the plunger and catch that needs to be pushed in.
http://www.celicatech.com/gallery/files/6/1/6/dsc04505.jpg

http://www.celicatech.com/gallery/files/6/1/6/dsc04506.jpg

Here you can see pushing in on the catch will let you push the plunger back in
http://www.celicatech.com/gallery/files/6/1/6/dsc04507.jpg

http://www.celicatech.com/gallery/files/6/1/6/dsc04508.jpg

Hook latched in, This is what you want to acomplish. Once you get the plunger reset, you have to remove the nut holding the tensioner in place and carefully push it back out of the engine, careful not to make the hook slip or you will have to do it all over again

Note: If you have a 6 sided 17mm wrench you can loosten the belt tensioner, and the 12mm nut on the top of the tensioner and slide it out of the way. This way you can remove the chain tensioner and to it like in the above pics.

http://www.celicatech.com/gallery/files/6/1/6/dsc04511.jpg

Once you push the tensioner back out, re-install the cams and make sure you timing marks are lined up

http://www.celicatech.com/gallery/files/6/1/6/dsc04518.jpg

Start installing the cam caps. they are labeled I2 I3 I4 and E2 E3 E4 etc. with arrows pointing to the front of the engine. make sure you install them in the right order
http://www.celicatech.com/gallery/files/6/1/6/dsc04519.jpg

http://www.celicatech.com/gallery/files/6/1/6/dsc04520.jpg

Use some assembly lube if you want
http://www.celicatech.com/gallery/files/6/1/6/dsc04521.jpg

http://www.celicatech.com/gallery/files/6/1/6/dsc04522.jpg

Tighten the cam caps just hand tight starting from the middle out

http://www.celicatech.com/gallery/files/6/1/6/dsc04534.jpg

Once the cams are tight, push the chain tensioner back in and tighten it back down. put the car in 6th gear and let off the parking brake. rock the car untill you hear the chain tensioner pop out and the chain gets tight.

Install the lift actuator , gasket first and the filter

Nice writeup. Did you use a new valve cover gasket too? (When I do this, I will anyway. Just curious if you did)

thats the TSB. i actually helped write that about 10 years ago. my way is a little easier after doing it a few more times

I never did it and I'll have to in the next weeks. I never even removed a valve cover of my life, but at the price this costs in a dealership, I'm more than motivated to do it myself. I'll have my niece's boyfriend help me, he's a mechanics.

What I like about the TSB is the fact the parts numbers are specified. I went to a toyota dealer with it this morning, $41 + taxes ($48)... when I can have them at $19.95 shipping included, from a Tacoma dealer in Washington, so I told him no thanks. He told me he never typed those parts number before in his system, guess there's not a lot of GT-S around here.

With your write-up and the TSB combined, this should not be too hard. :)
