Scrolling around on the disinformation pages....FB....i stumbled upon info that i feel was poorly presented. Here is what was presented.
"PUBLIC SERVICE ANNOUNCEMENT:
Someone is spreading bad information regarding 3v pumps sucking the oil pan dry. Well, they do not. All 2005-2010 3v engines and the 2007-2014 GT500 use this pump and do not experience their oil pans being sucked dry."
Lets analize this.
The question here.....is it possible for the oil pan to be ran dry by a 3v oil pump?...or any type of oil pump? Absolutely!
Yes its possible! Maybe not "ran dry" but starving, yes.
Ford made different styles of oil pick up tubes and oil pans for the same engine in many different platforms. The wrong combination of parts can provide a considerable gap between the pick up tubes opening and the pans bottom and vise versa, not enough gap. Some models came with a pickup screen cover that aided with oil suction.
Ideally you want the pick up tube opening to scavenge the pans bottom, like in any engine. Any bigger gap opens up the opportunity for cavitation from oil splash and slosh.
Lets think about this. The oil needed to feed the engine running,.... high rpm windage from the crankshaft, under the valve covers from the cams, timing components and drain back....You can start to see a few quarts of that oil is in suspension.
Look at it like this. Lets go racing. Roll through the burn out box, do your burn out. Pull up to the line and do the 7000rpm launch. Inertia causes the oil to slosh to the back of the pan, the high rev windage has alot oil in suspension, and now cavitation at the pickup opening is created. This also goes along with circuit track racing,...oil sloshing side to side at high revs.
And if the pickup tube and oil pan are not matched, the problem is compounded.
So yes, a 3v pump can "suck the oil pan dry"....if thats how we want to say it. Any pump can "suck the oil pan dry".
Under normal driving?...no, not really. Drag racing, track racing....absolutely.
Why would the author of such comment not offer an analytical approach being a guru of said engine platform. Im sure someone challenged him and he couldn't delete them, so instead he snickers a comment and like minded people followed.
