I just replaced exhaust manifold to solve the ticking problem the engine had until it warmed up.
Figured the hose from radiator to reserve was kinked and fixed that just recently to maybe solve overheating and coolant not running from reservoir to radiator.
No Coolant is noticably leaking after cool down or running temperature.
I am still having a large amount of white and what looks like condensation emission prior to normal running engine temperature. No matter outside temperature.
I don't know if coolant is in the oil but am about to change the oil to just to check.
I had a Jeep Mechanic tell me it's not the head gasket as I still have great power AND that the moisture is NOT consistant.
Any Random ideas?

Hi. You probably should have posted this in the Grand Cherokee section.
But if you are having to add coolant from time to time, and there is none dripping on the ground or spraying in the engine compartment, then the behavior you described could be a symptom of a blown head gasket, or a cracked head. The overheating problem is another symptom. The overheating may have been the cause of the exhaust manifold cracking.
The white smoke is the engine burning off coolant that is leaking into the cylinders while the engine is off. After fully warmed up, the engine can burn the coolant fast enough if it is still leaking that you won't notice it. Or the crack could be closing back off when warm.
Yes, they can blow or crack at 90K or earlier. And it may still run good for now. You may not see evidence of coolant in the oil. Before changing it, pull the dipstick and look for water droplets or discolored oil, looking like chocolate milk. You need to do this ASAP, as you may be ruining your bearings.
Further testing will be warranted if you are consuming coolant.
