I have a 2016 LML, tuned and deleted, EGR is also deleted and blocked off. It losses a little coolant every time I drive it, it’s not leaking anywhere I can see. it white smokes only on startup. It didn’t show any signs of combustion gases in the reservoir. We did a gas test on the reservoir on a cold start. The main coolant hose does not get hard on start up. Could this be a head gasket problem or something else. Thanks
