Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

At 63k the car had the head gaskets (HG), oil/water cooler, oil separator and several other parts replaced due to a bad HG.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

2 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1 / ORIGINAL POSTEROriginal post

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.
