Smoking Rb25Det

[DirtyDA]

hay,

I have a recently rebuilt rb25det motor (block) and due to a buggered injector and o ring it pretty much hydo locked the motor after a drain and refill of fresh oil due to it making its way to the sump ,it seems to be smoking quite a bit after re checking the oil it seems to still smell of petrol but i have rectified the injector issue ,

I am using a t70 (china) and a cheapish oil feed and i dont think it has a restrictor.I have bein told that these turbos need restricters or the bushes stuff out real quick but i thought that maybe there is still some fuel left in the oil and it has diluted it enough to pass the bushes into the turbo exhaust ? im a bit lost'd any ideas ??

If your turbo is bush bearing as you say then you should not use an oil feed restrictor. If it is ball bearing then you need the restrictor.

Ah ok ,Iwas lead to belive that all cheapish chinese turbos need atleast a 2mm restrictor in the line ...Thanks for clearing that up

That seems a little low, what head gasket, comp ratio pistons and ring gaps??

all factory just a whole bunch of bolt ons

you might have to change the oil again to get rid of the petrol completely, the breathers might be putting petrol fumes back in to the intake
