Comp turbo leaking oil in to hotside

[jade]

Hi

Started my car on Friday & it is pissing oil into the hotside housing, I am not using a oil restrictor As it not ball bearing, Anyone know if i should with a comp turbo or why i would be passing so much oil in to the hotside on a brand new turbo ???

I have dismantle the turbo inspected it it all looks fine

The turbo is a ct 458

I must of pumped 1/2 to 3/4 of a litre of oil down the exhaust, I have in inspected the turbo & it seems to be assembled correctly, I will need to tech spec's to check shaft seal. *******s !!! after all this trouble & waiting

Wayne,

Have you fabricated your own oil return pipe?

What size is Your drain line?

Describe Your crankcase ventilation system, pls.

[twoqu]

Difficult to see from the pics but its possible that the angle of the supply/drain is too great a deviation from vertical for the oil to return fast enough as it relies on gravity not pressure. Any restriction in the return i.e. a loop would also be a problem.
Could experiment by realigning the centre section. You would need to tweek the compressor housing as well.

center section is a garrett journal bearing CHRA,isnt it?
from the photos,it is hard to see, but water and oil lines are the same on the garrett as far as angles are concerned.at least you can see that easily

Wayne,

Oil return line was supplied by 034

was that oil return for a bearing turbo though?? and not for a garrett BB turbo?
