Thanks to everyone that helped with advice. Im home now.
It was #7 injector lin pitted leaking into crank case. A buddy warrentyed it at the dealer from a truck he was doing injectors on. Balance rates all -1 but one was +1.9, Return rates were 550 ish he says thats the best hes ever seen on any dmax (prob because he ges them all fd up)
Line must have moved a little into the pitted area upon reinstalling it after I did head studs
Thanks to all
