Soooooooooooooo......................what planet do you hail from, space brother?
Here on planet earth tightening old school tapered roller wheel bearings is done in INCH pounds not foot, 30 ft.lbs. and you're walking home in five minutes. I usually use 15-20 in.lbs., but much of it is feel for looseness just disappearing. A torque wrench 6 inches long.
Right on the no need for exact torque thing, I use anywhere from 175-200 ft.lbs. now on all 4 of mine, I like closer to 200 though.
Dunno about the 5 quart in 4.5 statement. Zetecs have a shallow secondary pan, if the addition of the extra half quart filled enough to let some show through the slat holes of the upper pan reinforcement, then one could lose a bit of power there as crank started eating oil, could induce some air injection into oil too. Maybe tear up a motor under hard use? Not like earlier stuff with more distance there. Ford spent a bit of time designing that middle reinforcement to recoup a bit of friction HP loss.
I have not filled up a pan with 4.5 quarts to check level, but I will if motor ever comes apart, I like to know things like that. Problem is, I can't seem to break one of these. Not gonna disassemble a perfectly running motor like I would when I was young and stupid................
Maybe someone else can chime in.
