smg is on a distinguished road

i recently did both heads and 3 timing chains on my 4.7 also. ran fine for 250 miles then at idle oil gauge would go to zero and come back to normal and check gauge would come on and it stalled. i pulled the oil pressure switch sender and put a psi gauge in its place and had 60-70 psi at idle. i changed the pressure switch and it didnt help. had foamy water mixed oil when i did the heads. one was cracked between the in and exh valves. i thought maybe the oil/water mix effected the gauge. now im thinking about the oil pump components but first im going to put the psi gauge back on and let it idle longer to see if it goes to zero.
