Thanks in advance guys, i have a freshly rebuilt 6.0 LS mated to a T56 in my 71 Cheyenne. Problem is that after driving it for a couple of minutes i start seeing smoke (bluish black) i assume oil, start coming from the exhaust. Im running a 78 mm turbo and noticed today that the turbo was leaking from both sides of the turbines. From what ive read im having excessive blow by or incorrectly set up pcv. What are some ways to set this up correctly or any ideas?
My current setup is : Drivers side valve cover (with pcv) hose to top of Catch can (non vented). Then from catch can to intake manifold close to throttle body.

Passengers side valve cover only has one opening and that is capped off.

My piston rings were gapped 26 top ring and second ring at 28.
Thanks again guys
