would a smaller oil restrictor help this problem?
right now i am running a 0.065" oil restrictor that came with my turbo.
oil feed is a -4AN.
oil return is a -10AN, as short as i can make it and goes only downhill. maybe a small section that is horizontal.
engine oil pressure is 80~90 psi above 3500 rpm.
i was told there was blue smoke coming out from the exhaust when the engine was under load.
after a hard run, i can also see smoke coming from the turbo, and that smoke contains oil. the engine bay area around the turbo has a film of oil from this smoke.
i believe oil was seeping out the exhaust side. i have yet to take out the intake piping to check for oil in the pipe.
the turbo was brand new from Precision when i installed it.
it is a ball bearing turbo.
would using a 0.035" restrictor help?
or should i troubleshoot else where?
would high crank case pressure cause the blue smoke too?
