hi, my vr6 is loosing about 2ltrs of water a day with no obvious leeks, the engine runs but after about 20mins of driving, it over heats way steam cumming out the water bottle, i have flushed the system out and there was no blockages or that, i have spoke to a few people, one has mentioned that my head gasket could be gone, there is no oil mixing with the water but if it has split near the pistons, the water is slowly leaking into the cylinders and evaporating, should i not see a big drop in performance if this happens?? Thanks
