detailed description of oil feed and return please.. pics are a bonus..

could be 1 of 3 things...

1. Seals took a crap
2. Oil pressure/volume is too much from large feed line
3. Oil drain is bottlenecking it all

or.. all or any combination of the above are possible.

3an braided steel oil feed, with a 10mm rubber return to the sump 6" long.

no idea of the pressures.

The turbo was rebuilt in 2001, could it of "gone" this fast?

WebGeek

yes, it can, especially if the oil feed and return isnt done right.

just put a bleed valve on your feed, this is cheap,easy, and if it doesn't work, and you're positive that your return is good, then yes, the turbo prolly needs new seals.

ok, heres the good news!

compression test results

195 200 200 195

so i know its not the head gasket,

i also started up the car from cold and no smoke!, im guessing that when the oil warms up then it thins out and goes passed the seals?

i pulled the return hose off from the turbo and oil came out from the sump! so i'm guessing that the return is no good (not falling freely into the sump!)The return is welded as high as it can on the sump so what can be done? an extra smaller tank perhaps?

also gonna get a oil pressure gauge and test the pressure in the oil feed line.

How do i find out the correct oil pressure that is needed for my turbo?

And! is my turbo now any good or shall i just get a reconditioned one? have i ruined the seals by pushing the oil through them?

WebGeek

Is there a nice downware slope or angle on the return line?

civicvtecb16a

YES

WebGeek

is that 10mm return 10mm OD or ID?

dunno what to tell ya... -10an is reccomended for return. I dunno what ID that is in mm. If its close, then i would venture to guess its the seals in teh turbo.
