can anyone tell me why my and many models of nissans--will lose the oil film on the cylinder walls and not crank----take the plugs out add some oil--turn it over and it fires and runs fine--my 90 300z has done this twice on me--but after talking to my buddy at nissan specialties --he says he see's it all the time---does anyone know what is causing this???????

I will send you a PM with a contact Gary
