Can the IPR valve be removed on 03 models the same as 04 and up (meaning do you have to remove turbo and intake on the 03 to remove the IPR valve)?

OK so I dove in. Great news is that it took me a fraction of the time. Especially since I didn't have to get out the torch or grinder to get any bolts off. I did manage to spill about 8 quarts of oil on my landlords garage floor.
So I notice some oil pooling under the drivers side of the turbo charger. it seemed to come from the pipe that comes from underneath the turbo charger. Could this be the source of my oil leak. I also noticed that when I was loosening the exhaust manifold bolts on the drivers side that there was oil dripping off of the block. Seems like it came from the same place.
I took as many pictures as possible. Any insight?

Fixed the album. Thanks for pointing link issue out. Could the oil drain leak cause a no start. Doesn't seem like it from what I am finding. I suppose I do need to replace it regardless.
There was some oil on top of the tube that feeds oil into the top of the turbo. Could that be an issue?

Here is a new link to the album.
It looks like there was caullk along the back of the HPOP cover?? Why would someone do this. Also the last picture shows (not very clearly) what looks like s6 or more attempts to drill into the inside of the cover.
How do I get the draintube off? Do I need to? The gasket on the drain tube looks fine to me. The seal along the back on the cover looks like it could be the issue.
Thanks for all the help!!

Are you referring to the turbo drain tube that you already have out????? Here's a picture of the 03 HPO system: http://dan.prxy.org/Truck/6L_bible_h.../Page_040.html

Ok I have everything including HPOP out. So far I have not seen any obvious signs of a bad gasket, o ring etc..
I applied air to the hole in the top of the HPOP and heard no leaks, Flipped it over applied air in the bottom hole. Air came out of the top hole. Now when I apply air to the top hole I hear a little air coming out of the bottom hole. No other signs of leaks that I can see.
I took the ICP and IPR out to inspect. I noticed that the IPR had no screen over it. I looked in the hole and the screen is stuck inside. The screen isn't broken. The screen is farther into the hole than the oil inlet hole inside the IPR hole.
Any suggestions on the next step?

IPR valve getting hung from contamination in the valve most likely your problem if you can't find a leak with air. The pump itself WILL have a little air leak from a bleed hole but this is normal. I'd advise you to dig out the screen and replace the valve entirely. Reassemble and air test. You'll have to apply 12V to the IPR valve to command it closed while you retest but don't apply voltage for more than about 30 seconds or you could damage the valve.

Do you have the discharge tube disconnected from the branch tube? If so, insert a rubber tipped air chuck directly into the branch tube to do your air testing. By doing it this way, you remove the high pressure oil pump, IPR valve and discharge tube from the equation. If no air leaks are heard, you won't need to remove valve covers to pinpoint further.
