Question about metal in oil?
Hi,
I've just bought a new to me 67 LeMans project car. It's got a late 60s WZ code 400 with a huge rowdy cam. Upper valvetrain looks stock, bolt-in oil drippers, stock rocker arms, spring shields, etc. Very clean up top, no sludge. Engine runs really well, great oil pressure, no strange noises. I changed the oil for the first time and cut the oil filter open. The oil was black, contaminated with carbon and some fuel. There wasn't any hunks or slivers in the filter pleats. But the oil itself was full of microscopic metal. It all sticks to a magnet, and looks like microscopic arrowheads. What could it be? Pontiac DNA? I have no idea of the engine's history or what's inside it, other than it had a history of carb issues. All I know is it runs like a beast. All 8 cylinders are dead nuts at 150 PSI on a compression test. Should I run some cheap oil through it for a few minutes to see if it clears, or do I need to dig deeper?

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
