Riddle me this?

Section 03-01B-41 under the lubrication system the bible lists a relief valve spring as to which its (force @ length) is 34.5 lb./in. Now, I've taken apart a 3l oil pump before (gerotor) and failed to locate a spring, although I wasn't looking for one I'd think it'd be obvious. Can anyone shed any light on this oil pump relief valve spring?

It isnt REAL obvious.

But it is there...

So..my question is, can this spring be replaced with a different (firmer) spring to increase the oil psi threshold?

Yes,

Todd Cook of TCE fame mentioned that it could be done with a washer or two. To really do it right, you should use a tensionometer with a spring compressor adapter to measure spring tension before (stock) and after. Take yours apart and let us know what you find.
