Filter bases and/or cans may or may not be drilled/tapped for the fittings.
Even if the cooler is blocked or removed, pressure is not affected because the cooler bypass valve will open.

Ok that's Interesting. So some of the alloy block cars do have oil coolers? Checked the 500sl and it doesn't. I have a couple 380sl I haven't looked at and I do have 2 560sl parts cars I didn't check. So what part of the circuit does the cooled oil return to? Is it feeding back into the pressure side or back to the sump?
