[DeTomaso] 10 qt oil pans- And Oil Pickup Tubes

[Larry - Ohio Time Corp]

Hi Chris,

That is the time, care and love a motor needs. Most shops can not afford to
do this.

As my Dad told me, "Quality is the sum total of the details."

Guys:

Something to be aware of regarding the oil pickup tubes is that they are 
designed to install within approximately .375 inches of the bottom of the 
oil pan.  I've heard it said that the clearance can range from a quarter 
inch, to a half inch, but the books that I've studied all recommend 3/8" of 
clearance between the oil pan, and the oil pump intake pickup screen.

When I installed my 10 qt pan on my SVT 5.4L SOHC engine, I had to do some 
"tweaking".  And to ensure that the results were correct, I placed a 3/4" 
square block of modeling clay on the inner surface of the pan, directly 
under the pickup tube intake. Then I bolted the oil pan, gasket, windage 
tray, and baffle assembly togther.  Torqued it too.  Then I had lunch, 
returned, and disassembled the oil pan.  When I was finished, I -knew- I had

the correct clearance between my oil pan, and the oil pump pickup tube's 
intake.

One of the reasons I had the problem was that I remodeled the pickup tube, 
rather than use my supplied Armando pickup tube.  The Ford OEM oil pump 
pickup has a much larger, and smoother intake assembly that has been 
specifically engineered to flow as much oil as the oil pump will ever need. 
It also had a large (square inches of screen) screen filter inside the 
intake.

My replacement oil pump pickup was relatively crude.  I mean it was 
certainly serviceable, and I'm sure it would have worked just fine.  But it 
wasn't nearly as well designed or fabricated as the Ford SVT intake.  I 
sectioned the OEM intake and lengthened the tubing such that it equaled my 
after-market intake.  As this is a vital part in my engine lubrication 
system, I probably went a bit overboard in my fabrication.... kinda 
reminiscent of the way that nuclear submarine reactor coolant systems are 
built....

But the end result was a very solid, and precisely located oil pump intake 
assembly that is located exactly at the recommended height above the bottom 
of the oil pan surface.  And that small piece of modeling clay was all it 
took to ensure that I did the job correctly.... and will never have to worry

about the intake being at the wrong height.  It takes some extra time, sure,

but the peace of mind, knowing that the oil pump intake is at the correct 
height, is well worth those extra few moments of assembly time.

But, as usual, your milage may vary... and probably will...
