I installed this 2055 SMOH IO320B1A in the AD2 and found this in the filter after 27 hours. I guess mostly carbon? A couple flaks of chrome, I did install some new rings? What has me puzzled is the gray stuff on right? It's somewhat magnetic. I thought it was lead or AL until the magnet picked it up? Maybe it's something with iron in it?
I'm new at this. At least no slivers off my cam...so far.
This engine had been well maintained and stored well after an oil change. I had all 4 cylinders off and looked good inside. I changed all oil rings and a couple others. Been running it hard. Compressions are 78, 78, 74, 74/80 It had used less than 2 qts. in the 27 hours.
