Engine will smoke when you first start it. Ford says that this is normal and refuses to fix it. I have a 2008 F-150 under lease that does the same thing. If this was my '65 Ford doing this, I would replace the valve seals in it. Ford said the dame thing, but says it's normal on my 2006 & 2008. They are getting ready to lose a 3rd generation Ford man because they will not stand behind their products!!!
