Hey all,
My 1st post here,I am pulling my hair out over my 5.4 3 valve engine.
Back ground,
New phazers, timing chain& tensioners, New plugs ,New coils,Correct oil and filter (Motor craft parts)
Problem,
engine runs fine for 3 miles(cold) then oil pressure drops to ZERO(Gauge)on dash board. Then goes in to engine save mode.
Codes pulling up,
