your bearings may be bad try switching to a thicker oil and see what happens oil pumps only create flow not pressure bearings create pressure by restricting the flow

In 2007 I talked to a tech rep at Clevite and he told me the rod bearings for my sons 302 maverick were available in sizes from STD to .010 in .001 steps and then .020, .030 and .040. I don't know if 200 rod and main bearing are the same but it’s worth a try.....
