not really stressing here, but i noticed my coolant was kind of 'cloudy'. Did a search, and only found people yelling BHG. So, i checked the oil filler cap, looked good, same for the dipstick. Took a sample from the oil drain plug; clean blacked oil, no contamination. Fired the car up, no smoke out of exhaust.
just wondering if it's just the cooling system on my old old car. (150.000 miles)
