ok guys long storey short i have coolant in my throttle body, which i just figured out was comming from the valve cover vent tube. i blew the vent hose out onto piece of paper and some greenish brown coolant came out. thus meaning theres coolant under that front valve cover, which means a leaky head gasket right? i have slowly been loseing coolant over time, however the oil dipstick never showed any coolant in the oil. So am i missing something here or do i have hg that just leaking coolant into the oil and not into any of the cylinders?
