Oil lines or water lines?
Ok, heres the deal, i got this turbo from a fellow member, and needless to say this is my first turbo project. I need to know what lines are the oil lines and what are the water lines. Im thinking the two lines with the threaded male fittings are the oil lines, and the large tube line is one of the coolant lines. the reason i think this is because coolant doesnt go above 20psi or so, so why would there be a flare style fitting? Oil lines see 50+ psi all the time so im guessing thats the case, but id rather not waste this turbo by mixing them up. Honestly im not even sure wich side is the top, and wich is the bottom. I tried searching for pictures of the factory installment to understand what goes where, but i didnt find anything. I know HMT can help me here. Thanks!

Wow. I was going to respond but I don't want to feed you a BS answer.
Just GUESSING, I would think a smaller threaded hole would be your oil inlet. If there are 2 similar sized holes, I would guess those are the coolant lines. Whatever is left would be your drain.
Can you see any oil or coolant?

Re: Oil lines or water lines?
Not really, sorry for the crap-o-la pics $15 dollar wal-mart special owns. Im going to get some decient pics soon with my g/fs nice digi cam.
The two lines with the fittings are both different sizes. The smaller fitting is in the top picture, but its next to the larger tube. The other side with the single stud has a much smaller outlet hole, but i can spray wd40 into the large tube and it leaks out the small hole. If i spray it in the small hole on the other side it doesnt even seem like it goes into the turbo, it doesnt leak out the large tube. If i spray wd-40 in either side with fittings it almost immediatly flows out the other side.

Re: Oil lines or water lines?
Its a 3k k26 turbo. It seems to be in good condition. Not much shaft play maybe 1/2 mm, but i found some metal shards in what is hopefully the coolant tube from god knows what, thats one reason i want to know. It could be from where the lines were cut hopefully. I dont think the turbo is blown, but i really want to get it on there asap so i can find out if its gonna blow smoke or screw up or anything so i can rebuild it or buy another turbo.

Re: Oil lines or water lines?
oil drain is the fat line in the top pic (which is obviously the bottom of the turbo) the oil feed is directly on the other side of the drain (threaded small hole). The water lates are at 90' to each of them, looks like they are the thinner diamter stainless lines which have been cut.

You can't see the bearings by looking in the oil feed or drain holes. At least you can't in any turbo I've ever seen.
There should be oil residue in the oil drain, and then the feed would be exactly on the other side of that. The oil is fed over the bearings and then gravity drains it through the drain line.
The other two are coolant lines and there is no in/out, just hook those up however you want.
