Good info and you're right, the URO part is well made.
Here are procedure notes I made after doing the job last Sept:
Replacing the fat PCV hose that runs from the PCV nipple to the intake near the turbo:
1. Elevate front end of the car on ramps or jack and support with jackstands (block the rear wheels)
2. Remove the center plastic shroud that is located under the front end.
3. Put a clean pan under the car large enough to hold 2.5 gallons.
4. Best to do this step with a cold engine. Disconnect the little water hose (about 4" long, 5/16" inside diameter) located near the turbo intake. A lot of coolant will drain out. It will drain faster if you remove the cap from the expansion tank.
5. Disconnect the PCV hose from the PCV nipple. It just pulls off.
6. Disconnect the approx. 10" long hose that runs from the throttle body to the center of the fax PCV hose.
7. Disconnect the fat PCV hose at the intake (near the turbo).
8. Pull the metal pipe out of the old hose. If that's too difficult, then the old hose can be cut away. I used a pair of tin snips.
9. Clean any crud off of the metal pipe.
10. Smear Vaseline on the end of the metal pipe that exits the center of the fat PCV hose and insert into the nipple hole that it exits. The purpose of this step is to lubricate this little section of hose because it is a very tight fit.
11. Insert the narrow end of the pipe through the bottom of the hose and feed it up to the nipple part where it is supposed to exit. You can feel the location of the end of the pipe through the hose, like pressing a shoe to find the end of your big toe. The narrow end of the pipe will want to continue to follow the fat hose. You have to figure out when it is at the entrance of the nipple and force it to go into the nipple. If you see the base of the nipple swell, then the pipe is following the correct path. If it doesn't swell, then back up and try again. When you see the nipple swell, keep the pressure on the pipe so it can't squeeze out, and then force it all the way through.
12. Connect the hose/pipe assembly at the intake near the turbo. Route the other end through the tight spot between the thermostat and throttle body and connect it to the PCV nipple on the valve cover.
13. Attach the two hoses, the little one near the intake and the larger one that goes from the end of the pipe to the throttle body.
14. Pour the coolant back into the expansion tank and install the expansion tank cap.
15. Look for coolant leaks. If none seen, then start the engine and see if it leaks after warming up.
16. Replace the center plastic shroud and lower the front end of the car. You're done. If some coolant is spilled, then remember to top off the expansion tank after driving some to get out all the air bubbles.
