The results from an abnormal sample from my Dad's 2003 Chevy Venture, that I had long considered lost, came in today. (A little over two months, after sampling) The odd thing, apart from the time it took, was that I had sent the sample to the ALS Tribology lab in Atlanta (Amazon WIX kit), but the results came from their lab in Ohio.
The vehicle had a bad lower intake manifold gasket and coolant was getting into the oil, causing sludge. The LIM was replaced. Sorry for all the "Unknown" entries -- this is my Dad's vehicle and he's not as meticulous as I am about this stuff.

BITOG: [cut-open] AC Delco PF-47E (Sludge in Center)
Better late, than never, I suppose.
