Oil leak paccar mx 13

My blowby tube actual has a drip to it and the crankcase ventilation module that it connects to is covered in oil. The big lines that come down from front valve cover and attach to it appear to be leaking somewhere as there is greasy dust buildup all over it in spots. Dont think its the ventilation module. No codes and if i lay oil cap upside down on oil fill hole and rev motor it doesnt blow it off but seems to be consuming a bit of oil lately and making a mess underneath truck. Any ideas?? Thanks in advance
Thanks in advance

 

Should wet oil be coming down through that tube and leaking out making a mess?thinking about removing the ventilation module and seeing if the filter is replaceable and maybe adding some heavy oil to thicken it up

 

Mines epa 10 and dealer said its an electric spinner like u said so maybe the leaking line coming down is my problem. Thanks for the input. I appreciate it very much.

 

I gave him my vin so he mus be a dummy,thanks man

 

Oh have you any experience with a product called AT-205 reseal to recondition engine seals and if so do u recommend or no?
