Only spec given is 2500 RPM when hot- 40-60 psi. It should at least have 6-11 psi at idle. What is the car doing, is the oil light flickering??? If so is the pressure switch leaking???

Re: 2000 Taurus 3.0 V-6 Oil Pressure Low

At idle, light is on. I put a gauge in it and only had 5 psi idling, hot, and 20psi at 1500 RPM.
I drooped the pan today and pulled a few rods and mains. Copper showing, but crank looks good. I have some debri in the pan that , at first I thought was bearing material. All bearings shell are in tack. ???
I can't ID the debri. It sticks to a magnet.
I can see up into the cylinders and there is no scoreing or unusual look to the pistons or pins.
It almost looks like some kind of oil slinger pieces???????
There was no engine noise while running,. although if I let it idle too long the valve started to tap....lack of pressure for the lifters I suppose.
I, at this point am at a loss.

ANY SUGGESTIONS FROM ANYONE?

If you can get a picture of the part, we may be able to know what it is. I'd pull the rest of the rods and see what they look like. Sometimes one will be completely gone, Did you remove all of the Main bearings? One has thrust bearings to keep the crank centered.

Re: 2000 Taurus 3.0 V-6 Oil Pressure Low

The debri did not come from the rods or mains. I checked them all.
There is nothing in this engine that relates to this material EXCEPT possibly a cam bearing.
Since low oil pressure is evident, I have no choice but to pull the engine and tear it down.
The car is in excellent shape and it would be a shame to throw it away.
Since it is a 2000 Taurus it may not be worth more than $2K running, and probably worthless not running!
I guess I know what I'll be doing the next few days.
Thanks for the help anyway!
