My husband drives an older Toyota 4Runner. Lately, he has been having a problem with getting oil into his coolant. At the shop, they did a full system flush and found nothing. They put pressure on the radiator and found no leaks. The head gaskets are fine. The leak is in only one direction ---> from the engine to the radiator (which I guess doesn't make any sense, because it should be going both ways). Everyone is baffled by this problem, even the mechanics, and can't figure out how he is getting oil into his coolant without coolant getting into his engine or leaking. Has anyone out there had a similar problem and if so, what was the cause? Or does anyone have any legitimate ideas? He just replaced the head gasket...that is not the problem! Professional mechanics have looked at this every which way and can't figure it out! Only serious answers please!
