Just changed engine oil this morning and discovered a small quantity of metal filings (very thin stands and small) in the oil tray after draining the sump. She's a K2 with 73,000 miles on the clock. Anyone got any ideas or is this normal? Also, there's been a little bit of imulsified oil in the oil filler cap.... just a smidgen.... maybe due to weather turning extremely cold and wet up here in Scotland? Don't think that my opening the cap to keep checking over the past couple of months is helping. No power loss etc.HELP!!!!! Any feedback greatly apprciated.
