I was doing a coolant flush on my '90 3FE. I used a chemical cleaner and let it soak and then drive it to thoroughly get into all aspects of the cooling system, over a week. When I started I wasn’t getting a lot of heat out of the heaters, front or rear heater, but now they are super hot. I couldn't believe the junk that came out. I thought I was good, but now I’m not so sure. I put in clean water but I always get a little bit of oil (I believe) out into the bucket. I water flushed it for a few hours but it is not oil free. I flushed it with out the running the rear heater, then the front heater but always the same result. I recently changed a lot of gaskets on the engine, side cover, oil pan, oil cooler, basically any gaskets that include oil in the engine and all the coolant hoses where changed, except the ones going into the firewall. When I drained the oil I didn't notice any water in the oil. Do the heater systems use oil? Oil cooler bad? Any thought?
