Still putting out blue smoke on startup.

My truck is still putting out blue smoke on startup even in summertime temps. It also puffs a little black too. I had the motor out and replaced the oil pan, front cover etc. Also did the injector o-rings. The injector cups did not look damaged or cracked at all. And i made sure to clear them out before putting the injectors back in. Could a seal in my turbo be leaking oil into the downpipe?
My ccv is routed to the back of the truck into a catch. Could a restriction in the ccv system cause the turbo seals to go out?. Most of the injectors look original and the truck has 305,000 km on the odo. Could the injectors have internal wear or damage that would cause oil/ fuel to leak into the cylinders. Sorry for rambling. Trying to figure this issue out.
