Happy Easter Folks,
Sooooo, I did an oil change last week and found the stuff you see in the photos nestled in the filter media. It is green in color. It feels firm but is a bit mailable (I hammered it out on a pies of steel and it can be pounded flat without shattering). A freind of mine has said it's cam chain guide material, but I never seen that present as green...and it's very green; it looks like finely chopped capers. Oil has 6000miles on it, filter has 12,000miles (got to the hangar and realized I was out of filters for the last change).
Many thanks as always!
