2001 jeep grand cherokee oil in coolant have engine apart no problem with head or gasket
It's possible that the old head gasket has de-laminated and the oil is passing through the inside layers of it. That is sometimes difficult to see.
Too late to check now but you should have checked the oil in the engine for coolant intrusion. Once apart, there always will be some in there so looking now is not valid. (why you always need to change oil after changing a head gasket).
Some '00 4.0L heads develop micro cracks that are difficult to find...it's possible you have an earlier head than the vehicle build year.
Also, have your radiator tested.... there is a transmission oil cooler in it if it's an automatic trans.
If it fails, you will also have oil in the cooling system, but it will be trans oil.
If you originally had coolant loss and steam from the tailpipe or you had a hydrocarbon test done on the cooling system I'd suspect the gasket or the head. If not, put the new gasket in and have the radiator tested. Same as coolant in the engine, if the cooler went bad, change the trans oil.
if it turns out to be micro cracking, either replace the head or use one of the high $ block sealers
to stop the seepage. 'Though I don't like using sealers, on micro cracks they seem to work pretty well if the directions are followed exactly..
