Oil in Cooling System
Hi everyone. I own a '99 996 that has developed an oil leak into the cooling system. At 98k mi. a beige colored sludge appeared in the coolant expansion tank.
At 63k the car had the head gaskets (HG), oil/water cooler, oil separator and several other parts replaced due to a bad HG. My initial reaction to the sludge was the HG, but the engine idles and runs smoothly; no water in the engine oil, it maintains normal operating temperature, even in stop-n-go traffic and the engine does not smoke. I replaced the oil/water cooler thinking it may have developed a leak and flushed the cooling system. The car was driven 1,1k mi. when a radiator vent hose blew just after the car was parked, at the same time I noticed a greater drop in oil level and increased sludge in the coolant expansion tank. Could it be: 1. Another HG 2. Faulty Oil/Water Cooler 3. Possible oil/water mixing at Oil Separator 4. Another possible point of cross contamination? I appreciate your feedback. |
