Help Jeep has bad head gasket?

I have a new jee p I just got a 2000 jeep grand cheorkee limited with a 4.7 all time 4x4. The problem is that the shop I took it to says I have a bad head gasket, they said they tested the antifreeze with ink and Said the ink was in the oil. I did a head gasket once on my old jeep and it had milky oil and coolant. But on this jeep there is no milky oil or coolant just the normal colors, it does have white smoke coming out of the tail pipe. But I can not smell "sweetness" on the fumes. I don't wanna junk the jeep can I get some help please.

Ps I do smell sweetness when I run it for awile by the radiator. There are no leakes, I have no heat as well. And the resavor is full all the time

Another possibility. Open the oil cap. Look inside between #3 & #4 cylinders. Is the head 'clean'. Then it is cracked...Been there....

With a 4.7L V8 if all you have is a bad head gasket you're lucky. The 4.7L V8 is known for cracks in the head (usually if overheated, but not always) and cracks in the block (exceptionally thin block walls are prone to cracking for no apparent reason). Any of these could cause oil/coolant mixing. If the leak/crack is small and slow you may not notice milky oil, but you could still have some mixing going on (if it is happening it will only get worse over time and will eventually trash the bearings).

Due to the high failure rate on this engine even used replacements are expensive (used parts prices are generally based on supply and demand and with a failure-prone engine such as the 4.7L V8 there is high demand and a limited supply of good-running engines).

Ok, I gotta stop posting late in the day!!! Didn't notice the 4.7 engine

If you have oil water crossing over there is some sort off breach. Check your plugs to see if any have been 'steam cleaned'. That would be the area where any breach is.
