Went for a cruise today with a buddy. He was in his miata behind me the whole time. He said it never gave the slightest hint of coolant smell, in spite of many hard pulls in front of him. But, after about 45 mins, the temps started creeping up and it was low on coolant again.... topped it off and back home, bummer.
I have checked for leaks at least half a dozen times now. I have run the system up to 28 psi (well above the 19psi cap I am running) during the leak check with no signs of external leaks.
So theres no evidence its going into the motor, and the only evidence of it coming out is whatever spits out of the tank. Something is causing 19psi of pressure in the system to be able to overcome that cap (I tested it myself).
I guess it HAS to be compression gasses getting into the coolant pockets. Fingers crossed its just an MLS issue and not a cracked block or cracked head.
Maybe next weekend ill be checking the head.... although it runs so well I am considering taking for a rip at the local drag strip before I tear it down. If I find a problem while its apart, it might be a while before its up and running again. I guess ill have to pay some attention to the auto awd at that point.
