I GOTS A RESPONSE FROM Mahle's Dan Begle, yay. Great company.


Ed,

I would agree with you on debris damage. Considering the length of service, this could have been some contamination on the build. You said it correctly when you noticed the debris coming mainly from the upper oil groove which makes a heavier debris path on the lower main.
