***engine taking too long to start - Smart key*** in some cases it takes too long the engine to start. Engine starter is working but is like the injectors are not supplying gasoline to the engine. It could be over 7 to 10 seconds starting the engine until the engine is running. After that I opened the hood and I found some oil stains on the valve cover. Also where the pcv ventilation is it looks like there is some oil vapors coming outside. Engine is the 2. 0 gdi (nu engine).
