Miriri Posted November 3, 2017 Posted November 3, 2017 Hi I have a Nissan xtrail T30 year 2005 with YD22 diesel engine. the oil is leaking to the coolant but not coolant to the oil. I changed the cylinder head gasket and even bowed the cylinder head to male it even but it is still leaking. The car is running just fine and is not overheating. what could be the problem?
Trevor Posted November 6, 2017 Posted November 6, 2017 It would be worth checking to see if there is an oil cooler that is cooled by water (similar to Volkswagen) in which case this could be perforated and allowing oil into the coolant. Or it could be residue from before the gasket was replaced and is still sitting in the cooling system
