I have a 1991 Chev K1500 with 4.3 V6 (86000 miles). I just purchased the vehicle a couple of weeks ago. It had a coolant leak. The radiator was wet, so I replaced the radiator and upper and lower radiator hoses, as well as replacing radiator cap. The coolant level continues to drop slightly (down a couple of inches inside the radiator). There are no visible signs of leakage under the vehicle, nor inside. There are no signs of coolant in the oil or vice versa.
After the vehicle has sat, there is a puff of white smoke upon startup. Guessing this is the valve stem seals leaking. The vehicle was owned by my current employer and saw short tripping in town, racking up only a 1000 to 1500 miles per year for the past 20 years. I do hear a lot of sloshing going on under the dash, but there are no leaks inside the cab. Could this just be an air bubble? If it were a head gasket issue, what would be the symptoms?
Thanks in advance!
