Ram 2500 oil leaking into coolant reservoir with no coolant in the oil on Ram 2500

Some Ram 2500 owners report experiencing oil leaking into the coolant reservoir, which may be attributed to several potential issues. A blown head gasket is a common cause, allowing oil to mix with the coolant and leading to the leak. Additionally, a faulty oil/coolant heat exchanger can result in oil entering the coolant system. Some owners have also found that a crack in the cylinder head or engine block may be the source of the leak, requiring inspection and possible repairs. Furthermore, issues with a faulty transmission fluid cooler could contribute to the problem. To accurately diagnose and resolve the issue, it is advisable for owners to consult with a qualified mechanic or technician.
