Might be a broken sylinder gasket ore onely a need for re-thigthen bolts for cylinder head. Be avare if this still continue after service. Make a mark on the coolant expantion tank after engine is cold ( over night), controll coolant vs. marking every day. PS.: coolant level can be reduced some over time because of local high temperature.
