turbo water lines?

[clutch-burner]

Ok so here is the story, got my wifes 1990 eagle talon all back together, ran great on the test drive except for a small drip of water coming from the rear turbo water line. What a pain because there is no way on earth I can get a wrench on that 17 mm flow bolt that secures the water line to the housing. so I just took the entire thing back off (header, 02 housing and turbo as 1 unit) now my question is there a certain tightening procedure I should be following when I tighten these things down? I got some new crush washers so am ready to give it another go. I would really like it sealed up this time as I really really really really do not want to have to remove this again. These things go on dry correct? no sealant?
I looked at converting to AN lines but I don't think I have enough room in the back for the pipe adapter then the fitting. is there any tricks to making this seal better or easier?
Thanks for the help

They go on dry with no sealant. I'm not sure what the torque spec is off hand, but if you follow that with the correct size crush washers, that should fix the leak.

Thanks ...I was pretty sure they went on dry, just not sure why the back one was dripping. I can't find any specific torque for em...I just snugged it down then tightened it a bit more....maybe I stuck a used crush washer in by accident

Dam I really wish there was a way to test this before I reinstall it? Can I maybe possibly plug the other side and apply vacuum? watch the leakdown if any? That work? I just don't wanna put it all back and have it drip again

I just got finished strapping my Evo16G on and know what you mean, it is a pain. With exhaust mani and turbo installed, these are the steps I followed with no leaks afterwards.

First took my lower water pipe and attached it to the main pipe itself. Tighten that hard to rech fitting enough so there isnt a ton of slop but not completely cinched down. This way you can see how parallel the free end is to the bottom of turbo, sealing surface. Now judge how straight the sealing surfaces are compared to eachother, and you might have the bend the pipe a tad if they are out of whack. If everything looks good, put your one crush washer in place (between pipe and turbo surface) then stick another washer on the bolt itself. Now tighten as best you can, preferably with a torquewrench to torque specs. At this point you will be thankfull that you already started the fitting which goes into main water pipe itself. Cramped for sure but try your best with whatever sized wrench just to thread it in. When that gets tight, of course get the right size and snug it up good. I found things were much easier after taking a wire wheel to the threads.

I hope that helps ya! During my whole process, it felt very solid when I made sure those surfaces were parallel and so far I'm only worried about my TB coolant hoses leaking, that lower pipe certainly isn't giving me trouble yet

I don't run coolant lines on any of my turbos, thats what turbo timers are for. Never had an issue and many,many other members deleted theirs also. But if you want to install them, a new set of proper size crush washers would just do you fine. You could have accidently re-used an old washer. You shouldn't have to be the hulk to torque the banjo bolts down. Just snug them down tight and then another 1/4 turn. Should be good to go.

I re used copper washers, hulked them down, no leaks! It's a bit of luck I tell ya!

Poor advice, never reused crush washers, it might have worked in this guys case, but its highly its not recommended.

Thanks for the info. being my wifes car I would really like to put everything back like I found it. I tell you what though if this thing leaks again I can definately see some coolant plugs in my future
