    turbo is throwin oil on the exhaust side could be seals or my return what do u think of the return setup im gonna change it so itzz on a 45 alll the way 2 the pan but i think thiz iz the reason my crossmember waz in the way so i went down and under then it goes on an upward angle to the fitting on the pan so i think its gettting backed up forcing the oil threw the seal

    That return line is horrible.

    It is straight gravity after the turbo (next to no pressure). You effectively added an upshill path for it.

    Get some real fittings like attached and make it straight in to the pan. no loops.

    Whats the shit all over the waste gate? Hows it gettin there?

    If Im not mistaken, the gate is top mounted and the turbo is hangin. Right?

    my first time installing turbo lol thanks for your opinion on it.. but yea i figured it waznt workin rite because it is gravity that makes it work but that dam crossmember in the older civics is in the way im gonna do some trimming to make it work.... thats oil on the wastegate from the turbo spittting oil on the exhaust side im guessing my seals are bad or my return is gettting clogged from the way i have it ran im gonna fix it so it comes down to the pan then hopefully it stops spitting oil

    you probably blew the seals from having improper flow in the return line.

    if it has no where to go, it spits out the seals.

    why don't you just clock the turbo so that the drain fitting is at a 45* angle pointing toward the pan and it seems like it would miss the crossmember. and like B said, your seals are probably shot bro. hate to tell ya that.

    You don't want to clock the oil fitting of the turbo very much. it should be straight up and down within a few degrees.

    If Im readin that right, youve got bigger problems then a clogged up drain line. You say the oil is comin outa the manifold gasket and waste gate. They are up stream from the turbo. That means the oil would hafta go against the exhaust flow, then force its way out of those spots. Ive never seen that happen, that I can recall.

    Thats why I asked about the waste gate in the first place.
