i changed the oil on the stang last night, used 10w40 valvoline senthetic blend 5 quarts and a motorcraft filter, so i cranked the damn thing up and let it run for about maybe 5 minutes, when i first cranked it up it had probly 60 psi oil pressure, after a few minuits the oil pressure started to drop, not like it drasticly fell but slowly dropped went all the way down, motor was still running but runing a little rough and it got a lot louder almost like it was knocking but not quite that bad, it was like i could hear the lifters rods pistons and all working in the motor, abnormal (it normally per's) im just wondering what it could be, because i have no ****ing idea, and anny help will be greatly app.

 

Try a new (another) filter.

 

yeah i thought of that but could that realy cause that big of problem, its almost like the oil pump quits once the frickin car warms up.

 

Yes, it can. Car was ok until the oil change right? It's not the oil right? Try a filter. I have come across this before. It's not impossible and it's the cheapest/easiest thing to try. Unless it just by coincidence took a dump on you.

 

i saw that problem yesterday with an s10... swap filters 1st.... then diag from there
