Okay, so it's not Kool-Aid. For whatever reason it's drinking coolant. In the last two weeks it's drank about 1/3 of the reserve. I did check the plugs, to me they look like they have a green tinge. It's not leaking anywhere from what I can tell. I assume it's the head gasket. It's not blowing any white smoke. I ran a compression test on it it ran 180 psi in 3 of the 4 cylinders, cylinder number 3 is at 190 psi. It's a 95 B18B, It's not overheating, it's not doing anything abnormal. I just realized after Solo II that it drank some coolant since I did the swap. Anyone have any ideas as to what it is?
