Turbocharger turbine seals are not like a typical o-ring. The turbine spins in excess of 100,000+ rpm's at times. a simple rubber or perfectly sealing o-ring is not possible, as it would burn up or cause the turbine shaft to get galled up. . They will leak if there is a vacuum ...

I'll check all this in the morning. Turbo bolted straight up to truck. Didn't have to clock anything like my cat turbos I get from bg. Said it was a genuine cummins holset reman. Came outta Memphis tn cummins warehouse. I'll check the mesh and crank case piping again in morning. It's straight piped, no mufflers or any restrictions from turbo to end of stacks. I've never pump a cac on this truck. I've had it about 6 months bought it from a buddy I'll check brand in morning. I got truck at my shop now. I got tired of paying for labor for them to keep throwing parts at it.
