LS6 Oil pressure problem...Confusing me
LS6 Oil pressure problem...Confusing me Ok, I just had heads and cam installed on my 01 Z06... Except for the fact it likes to blow the dipstick out of the tube and gets oil freaking everywhere.( this only happens like above 5k rpms. I've got a catch can and had a breather filter installed. But when I installed the breather... it like to smoke out of it when the car gets warmed up. I thought i blew a head gasket... but all the cylinders are the same pressure and there are no signs of coolant or anything in the oil. So I am stumped any suggestions anyone? Anything else I can try or check?
So what can I do about that? Or is there anything? It's becoming a pain to deal with. And I took the breather off because it was smoking oil through it. So, I have no idea what is causing it.

Here is my catch can routing. My TB doesn't have a tube going into it or anything. I have 3 connections and the one on the valve covers is blocked off by a plug. So what kinda set up do i need?

It appears that you have too much blow by, which begs the question - why wasn't it there before the H/C? First step is to do a leak down test and see where the pressure leak is coming from.

I believe your routing is wrong.
Valley cover line to catch can (top)> catch can to PCV valve > PCV valve to intake. (red lines)
Valve cover nipple to fresh air inlet (either TB or Bellow or tapped into mouth of TB area (custom see green dotted line))
See schematic attached:
