Thanks so much for the interesting discussion on the KT series and magnum series engines.

After a closer examination for crankshaft side play, I discovered that both sleeve bearings have excessive play in them. This is most likely where most of the oil pressure is escaping from.

If I had only had a low oil pressure light I most likely would have never have discovered the low oil pressure at idle because the light barely flickers. Thus I'm wondering how many other high time engines keep going, going, and going with low oil pressure.

Here is a couple of pictures of the screw dent on top of the piston and on the head. I thought you all might be interested seeing this
