about 120,000 miles checked all hoses and visual on engine at running temp no leaks oil and antifreeze look fine loses about a half gallon every weak ran a compression test had 175 psi in c1, 160 in c2, 185 in c3 and 180 in c4. Water pump has no play in pulley and no fluid leaking out of the weep hole any help would be appreciated
 
Probably head gasket failure especially if you cannot smell it or see it leaking anywhere. If you pull your spark plugs out you should be able to read them to determine if it is burning the antifreeze. Just type in reading spark plugs on google you should find some good article and photos. Otherwise it could just be leaking into the oil but I would suspect the oil level to change (too high) and to be a milky color. If it is leaking into your oil get it fixed fast! Antifreeze does not have the lubricating properties of oil and will cause rapid wear within the engine.

Let me know how it turns out.

Good Luck!
