hi my car is a 95 cx with a jdm b18b.
after sitting all night, when i wake up the next day i start my car no smoke but when i put it in reverse alittle white smoke comes out of the exhaust when i press the gas. i have a slight cam seal leak that runs down the head. i was wondering if its nomal oil burn off , or from the cam seal when the oil runs down it may seap into the head gasket? i need help? thanks

 

Its condensation in your exhaust system. Works the same way as seeing your breath when its cold out. Its normal.

 

what if its hot outside, i dont drive my car until it warms up also.

 

another ? could the oil that runs down the head cause the head gaskets to go out.
thanks

 

oil smoke is blue.

and i highly doubt that oil will affect a head gasket seal as all the ones that ive seen have metal on the actual sealing surfaces.
