Why will my 93 mustang engine not pump oil into the heads but in the oil filter?

If the oil pump was not correctly installed it will not pump correctly.The engine will burn up if you do not correct.Check oil return holes in heads to see if they are plugged.who worked on it last?Need more info.Why will my 93 mustang engine not pump oil into the heads but in the oil filter?

Because it's an american car!!
I am no mechanic, I have a little understanding of hydraulics, (applied here) I would go for the blocked port- check the pump, if there are any wear marks (grooves)on or in the gears and housing of the pump it will not work properly, it is a positive displacement system with a pressure relief valve in the circuit. Then you must check the pressure relief valve it may be broken in the sense that it allows oil to return to the sump before going to the head/crank etc.
u have aweak fuel t wonuldnt run it any more to u get apressure test guage
because it needs a ********.
you wil have a blocked oil channel to ur head in ur head gasket or camshaft if ur oil pressure is right
That doesn't make sense.
