Oil problem
I have a 1995 Ford ranger 2.3. I went to add a quart of oil and noticed on the cap some creamy oil. I check the dip stick and it had some creamy oil too. I then check my radiator level and it was ok. No water loss. I changed the oil and oil filter. Three day later I have a little creamy oil again. I check my water level and no loss of water in radiator. How or what is causing the creamy look in my oil?
