Hi, I have about 3 months with a 55 K mile Z4 2.5 i STD transmission, when I bought it I changed termostat, hoses, reservoir and radiator (non-OEM). I had an overheating one time due to low coolant, less than 2 minutes. Recently I had notice a coolant leak throught the cap when I turn off the car, its worse when its hotter, I live in a city where we get 38 celcius, I also noticed an oil leak on the motor from the drivers side and one time I got a white smoke throught the hood for a few seconds. I havent noticed any white smoke from the exhaust, and the oil looks fine. I'm really worried about and a mechanic told me that maybe a blown head gasket, hope you can help me.
