Y-Pipe removal/Oil leaks
Having spent cosiderable time diagnosing my (substantial) oil leaks, I now think, (almost certainly), I have oil leaks from the turbo oil input pipes. I managed to tighten the rear one from underneath the car, resulting in slowing down the leak, but not entirely eliminating it. I can't find a torque spec for this nut so I am concerned about over-tightening it. Anyone know the spec? I think I may ultimately need to replace the copper washers on one or both of the two inlet pipes. Can these be replaced from under the car without removing the Y-pipe, etc?
I may also have a leak where the main inlet pipe connects from the engine to the turbos, but I cannot yet see that area from above. I assume that I need to remove the Y-pipe but am hesitant to start before I know the full story. I looked at Rob Robinette's "How to install the Infini Y pipe." It appears that he has also removed the air box. Can someone tell me definitively what needs removing to get to the main inlet oil feed connection?
Lastly, it is still not 100% clear to me how to get the Y-pipe off. This is due to my lack of a detailed picture of the whole turbo assembly. (The shop manual doesn't help much). A good photo of the turbos assembled with the Y-pipe and also one showing the Y-pipe disassembed would help a lot. I'm sure there is one posted somewhere, but I've been unable to find it so far. Can anyone save me some time by pointing me in the right direction here?
Thanks
Dave

Dave... I had the parts guy at the local dealer print out that area for me.. it an exploded view and had all the part numbers that I needed. If I remeber right there is no real torque for the lines. I did a search and just gave up.
Luck to you

Thanks.
I'll try the parts list accessible from the forum and see how that looks and, if not, check with my local dealer.
The bolts seem pretty substantial and I expect that a lot of torque may just squash the copper washers without doing any thread damage, but.....

From my notes...may not be complete:
Take off all intake pipes/hoses along with the CRV and BOV hoses connected to the Air Box/Filters.
Remove both 10mm flange nuts that secure secondary Turbo air pipe and then from the top, wiggle air pipe out. You may need to remove the DP if you can't get to the nuts from the top.
Take off both y-pipe flange nuts on the secondary Turbo.
Unplug the 3 vacuum hoses conected to the CCV on the y-pipe. Take off Y-Pipe.

Thanks.
I guess, looking at Rob Robinettes photo some more, I see the air pump has been removed, (maybe it wasn't there in the first place). Is that something you have to remove?
