2.0 good running motor w/ carbs
I drive 60 miles every day and change the oil every 3k miles. Right now it has 2k since the last oil and filter change. Yesterday I checked the oil and discovered condensation water in the oil neck and some whitish foam. Nothing on the stick. Also found foam residue in the CB oil vent tank (hoses from the heads dumping through the tank back into the filler neck)
Search here didn't find any answers. On Samba several threads all saying not to worry. Consensus was the filler neck and upper vent tank never get hot and moisture accumulates.
Should I change the oil more often in the winter? What is foaming the oil? I've always used VR-1 20-50 oil and Bosch filter.
