I have a 96 formula and I have good oil pressure at start up but when the car warms up the oil pressure drops to about 20 psi and it starts ticking it sounded like a lifter but i replaced all the lifters and the oil pressure still drops and the ticking is still there and i dont know what eles could be wrong please help.

 

What oil are you using?

 

5 w 30

 

If you are using 5w-30 synthetic, I suggest changing to some good quality dino oil like 10W-30 or maybe 10W-40. My guess is that your pressure will go up and your lifters will quiet down and you will live happly everafter. JMHO
