Weird Radiator problem.... Please check this out

[89FHPLX]

My radiator is a 2 core, and its always been working great. the temp stays between 130 and the next line. Recently i had to change my timing chain and I also change my cam. When everything was back on the car, it ran great with the same temperture.

The weird this is now that every morning when I check the water, its half way down. Now I always check if there was any leaks. Anywhere on the engine and on the floor. I could be stuck in traffic and the car don't leak water. When I'm all done driving still no water to be found. I check the oil and it looks normal. I did not see any milky stuff in the oil. Its all fine and dandy!

Now where is all my radiator water going??
This is very weird.
remember NO LEAKS
NO MILKY STUFF IN OIL
NO SIGN OF NOTHING.
Its just goes away..
