Hi

I had my car on the hoist on saturday(bugeye) and i was just having a look around and i noticed a stain the size of half a 5 dollar note where the turbo and dump pipe meet. I know this is caused by burning coolant, so its either turbo seal is gone due to the fact it has a coolant feed or its the head gasket(s).
If you have experienced this just tell me what was the cause.
