I did some investigating and reading up on PCV system, Positive Crankcase ventilation.
I looked at a spare LIM and SC housing for a good hour.
I drew a line on the housing to show the metered air coming in from just in front of the tb blade.
These holes I blocked off now and running the metered air from the maf coupler through the front valve cover as pictured in above post.
I also found my vac leak.
It helps to have the coolant red!!
I seen a spot in a location on the ground that seemed strange.
Near cylinder #2 injector I found red coolant and then once core was off I found same in the LIM.
So I ran fluid through the core and couldn't get the core to leak. I don't know exactly where it leaked, maybe from outlet piping, and then it got sucked into the vac leak location in the back there. I am not sure.
I hope, really hope, core is not leaking.
I ran fluid through it, shook it wildly, and couldn't get it to leak.
So I buttoned everything back up and am waiting for it to all dry over nite this time before I try start it in the morning.
Learn somethig everytime I take it all apart.
