Was reading another posting of someone with a JD and a Kohler 321 engine asking what the white stuff was on his dip stick, It seems we had something in common other than the 321's, we did not run the engines much. My BMP (1983 Ford LGT-145) sits in the shop most of the time, and is only run long enough to move to the driveway to free up room in the shop to work on other projects. Well, after reading that post I decided to pull out BMP's dip stick, I was shocked as to what I found. This is clean oil that I changed around Sept last year. The white crud was about 3-1/2 inches above the full mark.
