I have had to add small amounts of water to the reservoir at least twice now in the past 2 months whenever the dash light came on with no discernible/visible leakage. When I first start the car, it runs rough as I depress the accelerator 3 or 4 times with white/blue smoke coming from the exhaust. After that, it levels out and runs smooth. There is no appreciable oil consumption. I'm due for an oil change now in 3K mile intervals and it's barely down a 1/2 quart. I went through a month or so this summer running hot (about 105-110C) until I had the replacement radiator replaced. I would say that the engine never technically overheated, i.e., never redlined during that period. I detect no water in the oil on the dipstick. The right front corner of the engine is wet with oil well below the valve cover but not at the valve cover. Could this be small amounts of water seeping into the first cylinder because of a warped head? Am I headed for hydraulic lock and a bent rod?
