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?

 

Hmm, you sure there's no visual signs of a leak? If not, then it's in your oil (as you suspected). Or are you mixing the correct amounts of water to coolant ratio?

 

not sure what the mixture would matter in this case, but you are correct, need to check the oil for brownish watery film, it's either burning it, leaking it internaly via head gasket or externally somewhere, the cyl. with the 10psi diff. stands out to me, it could mean it's leaking there and causing high comp on that cyl. the same as it would when doing a wet comp. check, which would increase psi on that cyl.

 

i agree with checking your oil... just to be sure.

also, place a few sheets of white paper under your car at night and check it in the morning to see if there's coolant leaking.

 

I just changed the oil recently, still looks and smells new. I checked the dipstick yesterday, and it still looks fine. I guess I'll change the oil again just to see if it looks like a milkshake yet.
